December in preprints

Posted by , on 4 January 2018

Our latest monthly trawl for developmental biology (and other cool) preprints. Let us know if we missed anything.


 

In their end of year round up, Science magazine picked ‘Biology preprints take off’ as a runner up 2018 Breakthrough of the Year, and ran a quote from Ron Vale –

 

“It’s a major cultural change in communication.”

 

In compiling this list over 2017 (which month by month gets longer and longer), it’s been exciting to witness the buzz around preprints grow and watch this cultural change take place. 

As for December, two organs seem to predominate – brains and kidneys! Also plenty of beautiful evo-devo and cell biology work, a good chunk of modelling, and the Drosophilists dream – a machine that collects your virgins for you!

The preprints were hosted on bioRxivPeerJ, and arXiv. Use these links to get to the section you want:

The BSDB’s advocacy strategy

Posted by , on 26 December 2017

BSDBlogoThe BSDB will soon publish its next newsletter. An important topic in that issue will be communication within our community and advocacy of Developmental Biology. See here a preview of the contribution by our communications officer Andreas Prokop describing the BSDB’s advocacy strategy.

The BSDB’s advocacy strategy

As argued in a recent PLoS Blog, there are alarming indications of communication fatigue in our community which weakens our ability to coordinate our activities and promote the importance of our science. But why do we turn off in this way at the worst possible time when conditions for fundamental research are worsening? As my colleague Sam Illingworth and I have argued in an editorial for a recent special issue about science communication, the likely reasons include (1) lack of awareness about the means and power of communication, (2) lack of incentives and external rewards for participation in science communication, and (3) lack of time: as academics we usually have more than 5 professions rolled into one, and the time demand in each of these professional spheres is steadily increasing, suffocating our productivity as scientists, let alone as communicators.

 

Notwithstanding, I argued in the above mentioned PLoS Blog that current circumstances cry out for communication and we MUST find feasible and effective ways to do so. As I argued, this is possible through the formation of collaborative networks of science communication. To achieve this, we need to communicate within our own communities to be able to coordinate our action. We need to make our individual contributions to science communication; if we are prepared to share the fruits of our activities, for example via The Node, this can then lead to the cumulative build-up of high quality and freely available resources and strategies. Finally, we need to make active use of and further improve existing resources and strategies; by reaching out jointly we will have a higher chance of gaining momentum and impact – all with the common goal of promoting dialogue about the science we love.

 

To lead the way in this direction, the BSDB has started an advocacy campaign together with The Node. The first step is simple and consists in putting together the best arguments for Developmental Biology and powerful examples illustrating these statements. The first draft of this document has been published on the BSDB site and on The Node. This resource can now be capitalised on by us all, but it also requires further community input to refine and complement the arguments – in particular also in the areas of Plant Biology and Evo-Devo which are not well represented. To catalyse this process, the editorial team of Development has complementary plans that will be announced in due term, and the BSDB has initiated a writing competition for PhD students and postdocs focussing on advocacy.

 

The gradually improving advocacy resource is intended to provide us with effective elevator pitches that can be used in dialogue with the public, students, other scientists, clinicians and politicians – and many of the arguments may fly well also on grant applications or in scientific publications. The overarching goal is to achieve wider recognition of fundamental Developmental Biology research as an important science branch that deserves public funding support.

 

But we should not stop there, and hopefully more members of our community will join in and help to develop creative science communication initiatives that carry dialogue proactively into the relevant target groups. Ideally, this is done through collaboration and long-term objective setting which has a higher chance of achieving sustainability, momentum and impact. To illustrate this point, a recent special issue on science communication describes examples of existing initiatives, explaining their origins and gradual developments. To facilitate the task, the BSDB and The Node have collaborated to put together a link collection (originally published on the BSDB site) which provides ideas, advice and resources that can be used and followed. We hope that these actions taken by the BSDB will help to raise the awareness of and participation in science communication and advocacy within our community for the benefit of all.

Spindle asymmetry drives non-Mendelian chromosome segregation

Posted by , on 20 December 2017

I studied molecular mechanisms of faithful chromosome segregation in mitosis and meiosis during my PhD and wanted to continue studying chromosome segregation but from a different angle. While looking for a postdoc lab, I learned about a phenomenon called meiotic drive where the selfish genetic element preferentially segregates into the egg during female meiosis in violation of Mendel’s Law of Segregation. I became quickly fascinated by meiotic drive and decided to join Dr. Michael Lampson’s lab at the University of Pennsylvania where they study the cell biological basis of meiotic drive in mammals.

Female meiosis is inherently asymmetric, producing only one gamete, and only chromosomes that segregate into the egg will be inherited to the next generation, while the rest will be degraded in the polar bodies. This asymmetric fate of the chromosomes creates an opportunity for them to compete during the meiotic cell division to remain in the egg, providing the framework to drive the evolution of genetic elements that regulate the segregation such as centromeres. Indeed, centromeric DNA is the most rapidly evolving DNA sequence in eukaryotic genomes despite its conserved function in chromosome segregation. Although examples of meiotic drive are widespread across eukaryotic species (plants, insects, and mammals including humans) with significant impacts on chromosome evolution, the underlying cell biological mechanisms are largely unknown.

The meiotic drive project was a perfect fit for me, where I could use my expertise in chromosome segregation to tackle an exciting evolutionary biology question. When I joined the Lampson lab, I overlapped for several months with a former PhD student, Lukáš Chmátal, who established the system to study meiotic drive in mouse oocytes. This was a great opportunity for me to learn about meiotic drive and the mouse oocyte system, both of which were new to me. My long-term goal is to understand how a selfish centromere interacts with the microtubule spindle to preferentially remain in the egg. In theory, a selfish centromere needs to find out which side of the spindle will take it to the egg. This implies some kind of asymmetry within the spindle, but the mechanisms were mysterious. So, my first goal was to understand the molecular basis of the spindle asymmetry, which is the main topic of this post. This spindle asymmetry project was originally started by Lukáš who established the basis before I joined the lab. It was also strongly supported by the collaboration with Dr. Carsten Janke at Curie Institut, who is one of the leaders in post-translational modifications (PTMs) on tubulin, which composes microtubules. Carsten suggested that we test the possibility that a tubulin PTM is asymmetric within the spindle, and indeed this was the case! Tyrosinated (Tyr) α-tubulin was enriched on the cortical side of the spindle, which will end up in polar body, whereas detyrosinated (dTyr) α-tubulin was enriched on the interior side of the spindle, which will remain in the egg. Subsequently, I found that CDC42 GTPase that localizes to the polarized cortex (green in the figure below) is required for the asymmetry in Tyr α-tubulin (white in the figure). Therefore, we proposed a model where CDC42 is the master regulator of the spindle asymmetry, increasing Tyr α-tubulin specifically on the cortical side of the spindle.

 

 

To support this model, I aimed to induce an artificial spindle asymmetry by targeting CDC42 to one of the spindle poles. I decided to take an optogenetic approach, which was previously developed in our lab using culture cells. So, I thought, “Okay, I just need to apply it to mouse oocytes”. But it turns out, it was not that simple. Science is not that easy… But thankfully, I had great colleagues Huaiying Zhang (Lampson lab) and Chanat Aonbangkhen (David Chenoweth lab at Penn Chemistry), who were working on this optogenetic tool in cell culture and helped me a lot to optimize the light-induced targeting in mouse oocytes. After multiple rounds of trial and error, optimizing the laser intensity and the constructs for the targeting, I successfully targeted CDC42 specifically to one spindle pole and found that it is sufficient to induce asymmetry in Tyr α-tubulin consistent with our model. (I personally think this optogenetic tool will be useful to study female meiosis in general because it allows us to control protein localizations spatially and temporally, which is of course important in mouse oocytes as well as in other systems)

Then, the obvious question coming next is how this tyrosination asymmetry helps a selfish centromere orient towards the egg side of the spindle. By carefully analyzing the attachments between selfish centromeres and the asymmetric spindle, I noticed that attachments were unstable when the selfish centromere faces the cortical side enriched in Tyr α-tubulin, which is the wrong direction for the selfish behavior going to the polar body. Also, I found that tyrosination destabilize microtubules. Therefore, a selfish centromere is more likely to detach from the spindle when facing the wrong side because of the high tyrosination levels, providing an opportunity to re-orient to the right side, where it can stably attach because of low tyrosination levels (see the movie below by AAAS, which nicely summarize this work).

 

Now we know a little bit more about meiotic drive at least in our system, but there are many big questions remaining. For example, we still don’t know how CDC42 regulates tubulin tyrosination. The link between CDC42 and the tyrosination is new, and the underlying mechanisms are completely unknown not just in mouse oocytes but also in other systems. It would be interesting in future to examine whether CDC42 regulates the enzyme that catalyzes tyrosination. Also, it is mysterious why the spindle is asymmetric in the first place. There should be some function in female meiosis in general, and the selfish centromere is just exploiting that asymmetry. Furthermore, we don’t know what activity at the centromere confers selfishness. Previously, our lab in collaboration with Ben Black’s lab (Penn Medicine) showed that a selfish centromere has expanded satellite repeat sequences and recruits more centromere proteins compared to the centromere of the homologous chromosome. I am very curious which protein(s) at the centromere is actually important for their selfish behavior. The above projects would help answer my long-term question − how does a selfish centromere interacts with the spindle to win the competition in female meiosis.

Biased chromosome segregation is not restricted to meiotic drive, but also present in some asymmetric stem cell divisions (e.g. muscle stem cell), where the old DNA strand preferentially remains in the stem cell and the newly synthesized strand segregates to the differentiated cell. Since the mechanisms of biased segregation in these systems are unclear, it would be interesting to examine whether we can extend the concept of biased segregation that we learned from meiotic drive to other systems.

 

Spindle asymmetry drives non-Mendelian chromosome segregation.

The people behind the papers – Alok Javali, Aritra Misra & Ramkumar Sambasivan

Posted by , on 20 December 2017

Neuromesoderm progenitors are a population of stem cells that contribute to the neural tube and somite-forming paraxial mesoderm, and promote axial growth of the vertebrate embryo. In the latest issue of Development, a new paper addresses the transcriptional control of fate determination in this fascinating cell lineage. We caught up with co-first authors Alok Javali and Aritra Misra and their supervisor Ramkumar Sambasivan of the Institute for Stem Cell Biology and Regenerative Medicine in Bengaluru, India, to hear the story behind the work.

 

Alok, Ramkumar and Aritra

 

Ramkumar, can you give us your scientific biography and the main questions your lab is trying to answer?

RS It all started with the question how do skeletal muscle stem cells stay mitotically dormant and then wake up to proliferate and differentiate in order to repair damaged muscle. I had worked on this question for my Ph.D. thesis research and identified genes that play a role in return of dormant cells into active mitotic cycling. From addressing the cell biology of muscle stem cells, my interest broadened and I studied skeletal muscle development as well as regeneration in mice as a postdoctoral researcher.  Currently, in my laboratory, we study the how the myogenic mesoderm develops and diversifies in vertebrates. Another major interest is on neural crest development, a new addition to my long-standing interest in muscle.

 

What is the current standing and future prospects for developmental biology research in India?

RS Developmental biologists make a small community in India and there is a need for expansion to derive the benefits of a strong community. However, things appear to move in the right direction. The number of developmental biologists in India has seen a significant spurt in the recent past, which I could gauge from the fantastic biennial meetings of the Indian Society of Developmental Biology. This augurs well.

 

Alok and Aritra – how did you come to join Ramkumar’s lab?

AJ I joined the graduate program of NCBS and InStem in 2013. Having prior interest in developmental biology, I did my lab rotation in Ramkumar’s lab. Being the first grad student in the lab, I had unique opportunity to be a part of multiple projects, which were still at their inception, ranging from studies on mesoderm patterning to mechanisms of fate choice in neural crest cells. This really excited me to join the lab for pursuing my PhD.

AM Prior to joining NCBS-inStem graduate program, I had trained in evolutionary biology and comparative morphology while studying zoology at bachelors and Masters level. This drove me to pursue PhD in either Evo-Devo or cell communication. Since Ramkumar’s work overlapped with my interest, I chose to join his lab.

What’s so intriguing about neuromesodermal progenitors, and what were the questions you were hoping to answer in your study?

RS Neuromesodermal progenitors (NMPs) are key for axial growth in amniotes. I wonder about snakes and whales and the changes in the regulation of these progenitors that enabled such axially extended forms of life. Two different observations by Alok and Aritra took us in the direction of NMP biology and emphasized previous findings that Tbx6 is a key regulator of NMPs. The broad question is Tbx6 function in these progenitors. In this work we laid the foundation to tackle this question by addressing the timing of Tbx6 induction in NMP lineage.

 

Can you give us key results of the paper in a paragraph?

RS, AJ & AM We show that Tbx6 is expressed in a subset of neuromesoderm progenitors based on spatiotemporal expression pattern in the NMP niche in early mouse embryos. Co-expression of Tbx6 with Sox2, a neurogenic factor in this subset, as well as genetic tracing of Tbx6-expressing cells corroborated our findings of Tbx6 in NMPs. Expression of Tbx6 in NMPs provides a key missing link in favour of the current model in the field, which invokes Tbx6 as mesoderm switch in NMP lineage. In addition, we show that Tbx6 mutant mouse embryos have five developing spinal cords in the tail. This novel aspect of Tbx6 mutant phenotype in the tail further supports the model. Thus, our results strongly support the role of Tbx6 in promoting mesoderm fate choice of NMPs.

Your work supports the notion that Tbx6 as a bistable fate switch – how exactly do you think it plays this role?

AJ & RS Tbx6, being a transcription factor, functions by activating or repressing its transcriptional targets. Published literature already suggests that Tbx6 indirectly supresses the expression of Sox2, a key neurogenic factor, to promote mesodermal fate. An interesting aspect revealed by our study is the existence of a regulatory cell state, wherein Tbx6 and Sox2 are co-expressed. This indicates a biphasic function of Tbx6 in NMP lineage; early role in braking neural fate and subsequent function in mesoderm differentiation. We are currently trying to identify the spectrum of Tbx6 transcriptional targets to elucidate the mechanistic details of its function in NMP fate choice.

 

When doing the research, did you have any particular result or eureka moment that has stuck with you?

AJ: Looking at five distinct neural tubes arranged beautifully in a transverse section of mutant mouse embryo was special. Not everyday one gets to see such dramatic unreported phenotype. This was not really a Eureka moment as we were not anticipating this phenotype. This observation was accidental. We were trying to get transverse sections of a mutant embryo post in situ hybridization as the staining that we had performed was not very clear. We were not particularly looking into the tail region. Since the embryo is ‘C’ shaped, along with the transverse section of the interlimb region, we got the section of truncated tail of the mutant. And there we saw five distinct neural tubes.

AM: Tbx6 is viewed uniquely as paraxial mesoderm factor, but while analysing the confocal images of immunostaining in E8.5 mouse embryo tail regions, I observed specific subset co-expressing Tbx6 and Sox2, a neural marker, within NMP niche. This was indeed a eureka moment for me, because in mouse gastrulation, this expression precedes paraxial mesoderm formation in NMP lineage. This implied that there is more to Tbx6 function than had been appreciated.

 

And what about the flipside: any moments of frustration or despair?

AM: The most frustrating moment was trying to obtain serial transverse sections of a very specific anatomy of tiny E8.5 mouse embryos for control experiments to demonstrate that our novel  Tbx6Cre transgenic line reports for Tbx6 faithfully. I had to ensure that I do not lose any section in the series. This experiment also provided crucial support to our observation of Tbx6 expression in the NMP niche.

AJ The most frustrating time was when I was trying to get non-oblique transverse section of primitive streak and node regions of e8.5 mouse embryos and saggital section of tailbud of e9.5 mouse embryos. The region of interest in both these cases is extremely small. Getting the ideal sections with all the necessary anatomical information to identify the region of interest took multiple attempts.

What are your career plans following this work?

AM: I want to continue in academia. My interest is to work on the evolution of bilateral symmetry and I want to start by looking into reptiles. But I will also be excited to explore opportunities in facilities such as mouse genome engineering facilities or Jackson Laboratories.

AJ: I am currently working on my PhD project where I am trying to understand the role of micro-RNAs in the development of another interesting cell type called neural crest. As much as I am attracted to academic research, along with it, I would also like to explore a career path in science education, which I believe is a need of the hour in India.

 

And what next for the Sambasivan lab?

I will address what next for my lab in the context of NMPs.  We are curious about the evolutionary origin of NMPs and tracing this in the chordate lineage.

 

Finally, what do you like to do when you are not in the lab?

AM: I always wanted to be a historian and study the evolution of human civilization. I have not had the opportunity before joining for Ph.D., however, now I use my time out of lab to fulfil this dream. In the past 2 years I have researched on how evolution of Indian civilization can be traced to have more connections to the development of agrarian systems rather than changes in ruling dynasties. Recently I started to work on socio-economic changes in pre-British era driving changes in Indian demography. This began with an amazing book: Rise of Islam and the Bengal Frontiers by Richard Eaton. Currently I have started probing into the concept of Sacred Feminine and evolution of Egyptian society.

AJ: There are few things that I usually do. Swimming or running is my stress buster. I love to play Cricket (famous sport in India), though I don’t get much time for it anymore. I also love to read popular science books

RS: This used to be an easier question to answer.
