We're thrilled to share our collaborative work with @Jothi_Lab on the human embryo atlas for human blastoid assessment (biorxiv.org/content/10.1101/…). This much-needed work by @hani_jieun provides insights into popular human blastoid models.
What role does the bivalent chromatin play in differentiating stem cells? Dr Dhirendra Kumar from @Jothi_Lab will join us next Monday to present his latest research on the regulatory role of bivalency in maintaining epigenetic plasticity. Joins via zoom. No registration required.
My Department at Thomas Jefferson Univ is hiring a new Assistant Prof. (ad coming soon) in any area of Molecular Biology and Biochemistry! It’s a great Department full of nice people with a lot of collaboration opportunities. DM if you have any question and please RT!
The Banaszynski lab is hiring a postdoc! We are a chromatin lab studying histone variant biology in the context of both development and disease. Help me spread the word and message me if you are interested. 1/
Decoding the function of Bivalent Chromatin in development and cancer. Bivalency does NOT poise genes for rapid activation BUT protects promoters from de novo DNA methylation. Bivalent domains have a function after all!

New insights on the function of bivalent chromatin. Bivalency does NOT poise genes for rapid activation BUT protects reversibly repressed genes from irreversible silencing. ‘Poised’ RNA Pol II incompatible with transcription; H3K4me3 not instructive
disq.us/t/3t9kpqt
Fun fact 3: Activation of bivalent genes is no more rapid than that of other transcriptionally silent genes, challenging the premise that H3K4me3 is instructive for transcription
Fun Fact 2: Loss of H3K4me3 at bivalent promoters is strongly associated with aberrant hypermethylation and irreversible silencing in adult human cancers.
Fun fact 1: H3K4me3 at bivalent gene promoters is a product of the underlying DNA sequence, persists in nearly all cell types irrespective of gene expression, and confers protection from de novo DNA methylation.
This figure is insane.
The extreme underrepresentation of z-values between -2 and 2 (which is just around the commonly used p-value threshold of 0.05) demonstrates publication bias/p-hacking/etc. Sharp edge near the threshold.
