DHODH Drives Sunitinib Resistance Via a Non‐Enzymatic Mechanism by Inhibiting TRIM28 Ubiquitination and Consequent VEGFA Activation in RCC

Advanced Science, EarlyView.
This non‑enzymatic function of DHODH drives sunitinib resistance by competing with TRIM37 to block TRIM28 ubiquitination, thereby stabilizing TRIM28 and activating VEGFA transcription. Disrupting the DHODH–TRIM28 interaction with lisaftoclax restores drug sensitivity.

The YETI gene: from Drosophila melanogaster heterochromatin to human craniofacial development. [PDF]

, 2011
In the present work, we have performed a functional analysis of CG40218, a heterochromatin gene encoding the YETI protein. YETI is a member of the evolutionarily conserved family of BCNT proteins whose function is still unclear.

Navigating heterochromatin [PDF]

, 2003
The condensed structure of heterochromatin differs significantly from euchromatin and DNA bound in heterochromatin is generally not transcriptionally active. Transcriptional silencing allows the control of gene expression and affords a novel mechanism of

Early-replicating heterochromatin [PDF]

Genes & Development, 2003
Euchromatin, which has an open structure and is frequently transcribed, tends to replicate in early S phase. Heterochromatin, which is more condensed and rarely transcribed, usually replicates in late S phase. Here, we report significant deviation from this correlation in the fission yeast,Schizosaccharomyces pombe.

Molecular and Cellular Hallmarks of Age‐Related Vestibular Hair Cell Degeneration

Advanced Science, EarlyView.
This study utilizes single‐cell RNA‐seq transcriptomes, advanced imaging, and electrophysiology to examine universal and cell‐type‐specific aging signatures of vestibular hair cells. The study shows that impaired hair bundle function is a key driver of age‐related vestibular dysfunction.

H3K56me3 is a novel, conserved heterochromatic mark that largely but not completely overlaps with H3K9me3 in both regulation and localization. [PDF]

, 2013
Histone lysine (K) methylation has been shown to play a fundamental role in modulating chromatin architecture and regulation of gene expression. Here we report on the identification of histone H3K56, located at the pivotal, nucleosome DNA entry/exit ...

Psychological Stress Associated Bile Acid Reprogramming Promotes Hepatocellular Carcinoma Progression

Advanced Science, EarlyView.
Depression is increasingly recognized as a risk factor for chronic diseases, yet its biological impact on cancer remains unclear. Using data from more than 490 000 participants across three international cohorts, we show that depression significantly increases the risk of liver cancer.

Histone variant H2A.W7 represses meiotic crossover formation in Arabidopsis heterochromatin [PDF]

In eukaryotic genomes, DNA is packaged into nucleosomes to form chromatin. The incorporation of canonical or variant histones into nucleosomes confers different properties and influences chromatin structure to regulate cellular processes, including ...
