Low-Fat, High-Fiber Diet Reduces Markers of Inflammation and Dysbiosis and Improves Quality of Life in Patients With Ulcerative Colitis.

Background & Aims: A high-fat diet has been associated with an increased risk of ulcerative colitis (UC). We studied the effects of a low-fat, high-fiber diet (LFD) vs an improved standard American diet (iSAD, included higher quantities of fruits, vegetables, and fiber than a typical SAD). We collected data on quality of life, markers of inflammation, and fecal markers of intestinal dysbiosis in patients with UC.

HDAC7 regulates histone 3 lysine 27 acetylation and transcriptional activity at super-enhancer-associated genes in breast cancer stem cells.

Chromatin regulation through histone modifications plays an essential role in coordinated expression of multiple genes. Alterations in chromatin induced by histone modifiers and readers regulate critical transcriptional programs involved in both normal development and tumor differentiation. Recently, we identified that histone deacetylases HDAC1 and HDAC7 are necessary to maintain cancer stem cells (CSCs) in both breast and ovarian tumors.
