Interestingly, recessive VSX2 variants are known to cause severe eye disorders (microophthlamia/anopthalmia).

We discovered that heterozygous variation can predispose to adult-onset retinal detachment, expanding the phenotypic spectrum of this gene

My lab at MSKCC in New York is hiring for two positions. Join us at the frontier of functional genomics, studying fibroblast state transitions, combinatorial genetics, and ECM in disease. Please share with anyone who might be a good fit! (Mustache not required.)

These 22 genes could put people at risk of long-term health conditions following common viral infection. Differences in these genes help explain why Epstein-Barr Virus can have lasting health effects in some people but not others.

#GeneticVariation influences how #EBV is controlled, and poorer viral control is linked with several long-term illnesses. @ryandhindsa.bsky.social @bcmhouston.bsky.social @caleblareau.bsky.social @mskcancercenter.bsky.social @astra-zeneca.bsky.social @nature.com blogs.bcm.edu/2026/02/03/f...

Our latest story is now on bioRxiv. We present PETRA, a new method for deciphering how sequence variants impact gene regulation at scale.

This work was led by Magdalena Armas Reyes, a @crick.ac.uk PhD student until very recently. Congrats, Dr. Armas!

New preprint on technologies to scale up CRISPR screens.

We use them to map 665,856 pairwise genetic perturbations and outline a path to comprehensive interaction mapping in human cells.

We also introduce an approach for cloning lentiviral libraries with billions of elements.

Varicella-zoster virus reactivation and the risk of dementia - Nature Medicine Large-scale longitudinal health records reveal consistent association of varicella-zoster virus reactivation with dementia.

A new Nature Medicine study analyzing health records from >100 million people in the US offers compelling evidence that reactivation of varicella-zoster virus (VZV) ,the same virus that causes chickenpox and shingles may contribute to dementia risk.

On the left - western blot of B16F10 cells wt and KO for CDK8. Our in house produced antibodies give a lot of unspecific bands. On the right same probes with antibodies preincubated with fixed CDK8 KO cells - there is a specific band and faint unspecific bands, which can be probably eliminated with increase of amount of KO cells.

Neat trick if you polycolonal ab's suck. Incubate them with fixed cells with a KO of your protein of interest, then spin. Protocol here: www.med.upenn.edu/markslab/ass...
I was amazed how well it worked on first try (I'm sure that I can completely eliminate unspecific bands)
