Antihypertensive and antioxidant effects of food-derived bioactive peptides in spontaneously hypertensive rats.

Hypertension significantly impacts the survival and quality of life of animals, often leading to chronic kidney failure. Current clinical drugs used to manage hypertension carry the risk of causing adverse reactions. In contrast, certain natural peptides have demonstrated the ability to safely reduce blood pressure by inhibiting the production of angiotensin.

FBXO38 mediates FGL1 ubiquitination and degradation to enhance cancer immunity and suppress inflammation.

Upregulation of FGL1 helps tumors escape from immune surveillance, and therapeutic antibodies targeting FGL1 have potential as another immune checkpoint inhibitor. However, the underlying mechanism of high FGL1 protein level in cancers is not well defined. Here, we report that FBXO38 interacts with and ubiquitylates FGL1 to negatively regulate its stability and to mediate cancer immune response.

TET2 is required to suppress mTORC1 signaling through urea cycle with therapeutic potential.

Tumor development, involving both cell growth (mass accumulation) and cell proliferation, is a complex process governed by the interplay of multiple signaling pathways. TET2 mainly functions as a DNA dioxygenase, which modulates gene expression and biological functions via oxidation of 5mC in DNA, yet whether it plays a role in regulating cell growth remains unknown. Here we show that TET2 suppresses mTORC1 signaling, a major growth controller, to inhibit cell growth and promote autophagy.

Intestinal microbial 16S sequencing and LC-MS metabonomic analysis revealed differences between young and old cats.

With the progress of society, the health problems of pets have attracted more and more attention. Recent studies have shown that intestinal microflora and related fecal metabolites play a crucial role in the healthy growth of cats. However, the potential role and related metabolic characteristics of gut microbiota in different age groups of pet cats need to be further clarified.

TET2 Suppresses VHL Deficiency-Driven Clear Cell Renal Cell Carcinoma by Inhibiting HIF Signaling.

Unlabelled: Inactivating mutations of von Hippel-Lindau (VHL) are highly prevalent in clear cell renal cell carcinoma (ccRCC). Improved understanding of the vulnerabilities of VHL-deficient ccRCC could lead to improved treatment strategies. The activity of DNA dioxygenase ten-eleven translocation (TET)2 is significantly reduced in multiple cancers by different mechanisms, but its role in ccRCC progression remains unclear.

Acetylation of BmAtg8 inhibits starvation-induced autophagy initiation.

Silkworm (Bombyx mori) is not only a model organism for scientific studies, but also a commercial insect for agricultural production. BmAtg8 (a B. mori homolog of yeast Atg8) plays crucial roles in macroautophagy (hereafter referred to autophagy), which is helpful for silkworm metamorphosis.
