Our miRNA story is now in @science.org ! We found a microRNA, not a protein, that finally solved a long-standing evolutionary mystery of wing coloration in butterflies and moths. (1/n)

A microRNA is the effector gene of a classic evolutionary hotspot locus
In Lepidoptera (butterflies and moths), the genomic region around the gene cortex is a “hotspot” locus, repeatedly implicated in generating intraspecific melanic wing color polymorphisms across 100 mi...

📢 Preprint! How does the environment of a father before conception influence offspring?

Even more, how do paternal genetics & ages interact with exposures to affect F1 outcome?

We tested this systematically, with intriguing findings & some cautionary tales🧵...

Embryonic Signatures of Intergenerational Inheritance across Paternal Environments and Genetic Backgrounds
The paternal preconception environment has been implicated as a modulator of phenotypic traits and disease risk in F1 offspring. However, the prevalence and mechanisms of such intergenerational epigen...

And another new preprint from the lab, led by S. Paul, K. Ilkhani, and N. Strozewski, in collaboration with Shvartsman lab: we identify ERK-dependent phosphosites in Capicua (Cic), and show in vivo that mutating these sites turns Cic into a “super-repressor”.

New preprint from the lab, led by Melissa Brown: we uncover a function for #Drosophila Minibrain/DYRK1A in the neuroepithelium, and show that Mnb engages the Reps/Rlip/Rala signaling network to control brain development.

It's finally out! Our second single cell "atlas", this time of the mouse seminal vesicle -- probably the last major tissue in mammals to be subject to single cell RNA-seq. 1/n (let's see if I can figure out threading on bsky)

Mutations in Argonaute proteins can significantly disrupt the miRNA biogenesis and functionality in target repression, and cause neurodevelopmental diseases. But how? Check out our new paper about modeling Argonaute Syndrome in C. elegans.👇👇👇👇

Sometimes I come across a paper that reinforces all over again why I found/find biology so fascinating. This answers a question my son asked me once when he was young. Had no answer for him then but will forward him this!

Cell biology is .... truly awesome.

My take on what cell biology means to me in the latest issue of Cell celebrating their 50 years. I really enjoyed reading the pieces from everyone. authors.elsevier.com/c/1iS4aL7PXm...

Big day for the Ogden Lab! Today is my 15th anniversary of having a lab at St. Jude Children's Research Hospital - AND - Our latest paper led by @erichall.bsky.social just dropped! Interested in cell communication and tissue development? If so, ✔️ it out! 🧪 👩‍🔬

A great bunch of folks did this, but I have to mostly highlight the incomparable Qiangzong Yin. Also kudos and thanks to JM Peters, with a very complementary MS on sperm 3D structure...we cosubmitted with them and had nothing but a wonderful and open experience with them. Happy Holidays y'all!!

Hey hey! It's finally out, almost a year to the day after we posted the preprint! I've already done a short Skytorial on this, but the upshot is that we think most, if not all, measures of mouse sperm chromatin are artifacts of cell-free DNA. 1/n

over a decade ago, Hong Duan and Josh Kavaler figured out that KO of Drosophila mir-279/996, encoding related seed members with overlapping function, selectively obliterates development of "Johnston's Organ" (JO), the insect auditory center (i.e. "ear"). 2/5
