The histone demethylase KDM5C enhances the sensitivity of acute myeloid leukemia cells to lenalidomide by stabilizing cereblon.

Background: The protein cereblon (CRBN) mediates the antileukemia effect of lenalidomide (Len). Len binds to CRBN, recruits IKZF1/IKZF3, and promotes their ubiquitination and degradation, through which Len exhibits its antileukemia and antimyeloma activity. Therefore, the protein level of CRBN might affect the antiproliferative effect of Len.

In mammalian oocytes, large-scale chromatin organization regulates transcription, nuclear architecture, and maintenance of chromosome stability in preparation for meiosis onset. Pre-ovulatory oocytes with distinct chromatin configurations exhibit profound differences in metabolic and transcriptional profiles that ultimately determine meiotic competence and developmental potential. Here, we developed a deep learning pipeline for the non-invasive prediction of chromatin structure and developmental potential in live mouse oocytes.

Marek's disease (MD), a T cell lymphoma disease in chickens, is caused by the Marek's disease virus (MDV) found ubiquitously in the poultry industry. Genetically resistant Line 6 (L6) and susceptible Line 7 (L7) chickens have been instrumental to research on avian immune system response to MDV infection. In this study we characterized molecular signatures unique to splenic immune cell types across different genetic backgrounds 6 days after infection.

Difficult-to-heal wounds management accounts for about 4% of healthcare costs, highlighting the need for innovative solutions. Extracellular signals drive cell proliferation during tissue regeneration, while epigenetic mechanisms regulate stem cell homeostasis, differentiation, and skin repair. Exploring epigenetic regulation in adipose-derived stem cells (ADSCs) holds promise for improving skin injury treatments.

In Arabidopsis (Arabidopsis thaliana), light and circadian clock signaling converge on PHYTOCHROME-INTERACTING FACTORS (PIFs) 4 and 5 to produce a daily rhythm of hypocotyl elongation. PIF4 and PIF5 expression is repressed at dusk by the evening complex (EC), consisting of EARLY FLOWERING3 (ELF3), ELF4, and LUX ARRHYTHMO (LUX). Here, we report that ELF3 recruits the JUMONJI (JMJ) H3K4me3 demethylases JMJ17 and JMJ18 to the PIF4 and PIF5 loci in the evening to remove their H3K4me3 marks.
