ARE-mRNAs are actively degraded with tristetraprolin (TTP) in resting cells while they turn into stable messengers in activated cells. P38 plays a crucial role in stabilizing ARE-mRNA. Here we reveal that P38 activation represses the interaction between TTP and Ago2, thus restraining TTP from being targeted into processing bodies and stabilizing ARE-mRNA.

Proliferating animal cells maintain a stable size distribution over generations despite fluctuations in cell growth and division size. Previously, we showed that cell size control involves both cell size checkpoints, which delay cell cycle progression in small cells, and size-dependent regulation of mass accumulation rates (Ginzberg et al., 2018).

Ethnopharmacological Relevance: Huanglian Ganjiang decoction (HGD), which is composed of Chinese medicines with cold, warm, and astringent properties, has demonstrated significant therapeutic efficacy in ulcerative colitis (UC). However, the underlying mechanisms remain unclear, highlighting the need for a multi-faceted investigation. Disassembling prescriptions is a crucial approach for investigating compatibility mechanisms.

Organisms allocate energetic resources between essential cellular processes to maintain homeostasis and, in turn, maximize fitness. The nutritional regulators of energy homeostasis have been studied in detail; however, how developmental signals might impinge on these pathways to govern metabolism is poorly understood. Here, we identify a non-canonical role for Hedgehog (Hh), a classic regulator of development, in maintaining intestinal lipid homeostasis in Caenorhabditis elegans.

Background: Cerebral small vessel disease (CSVD) is one of the most common nervous system diseases. Hypertension and neuroinflammation are considered important risk factors for the development of CSVD and white matter (WM) lesions.

Method: We used the spontaneously hypertensive rat (SHR) as a model of early-onset CSVD and administered epimedium flavonoids (EF) for three months.
