First evidence of cohesin folding occurring in vivo and during cohesion together with a detailed description of the structural aspects of cohesin's elbow folding through a series of novel structures.
Yeast bromodomain-containing factors Bdf1/2 offer insights into the biological role of the BET family of transcriptional regulators, which is a promising target in cancer therapy.
For poly(A)-tail length to influence mRNA translational efficiency, poly(A)-binding protein (PABPC) must be limiting, mRNAs lacking PABPC must be stable, and translation initiation must be sensitive to PABPC levels.
Micromanipulation experiments demonstrate that HP1α strengthens interphase and mitotic chromosome mechanics and maintains nuclear shape by chromatin crosslinking, separate from histone methylation.

The TPL corepressor binds to the core mediator complex through MED21 to inhibit transcription while simultaneously priming repressed genes for rapid reactivation.
ARID1A deficiency in SWI/SNF complex promotes pancreatic tumor development by upregulating ALDH protein levels to effectively reduce cellular reactive oxygen species levels, leading to the significant attenuation of oncogenic KRAS-induced senescence.
