As a first line of defense, intestinal barriers could be utilized against OTA in order to prevent disorders. Natural product supplementation is one of the most popular strategies to alleviate toxicity induced by mycotoxins, but there is a lack of knowledge about how it functions in the teleost intestine.

Previous research has found that AFB1 inhibited zebrafish muscle development. However, the potential mechanism of AFB1 on fish muscle development is unknown, so it is necessary to conduct further investigation.
View Article and Find Full Text PDFOchratoxin A (OTA) is a common mycotoxin in food and feed that seriously harms human and animal health. This study investigated the effect of OTA on the muscle growth of juvenile grass carp () and its possible mechanism in vitro. Our results have the following innovative findings: (1) Dietary OTA increased the expression of increasing phase I metabolic enzymes and absorbing transporters while reducing the expression of efflux transporters, thereby increasing their residue in muscles; (2) OTA inhibited the expressions of cell cycle and myogenic regulatory factors (MyoD, MyoG, and MyHC) and induced ferroptosis by decreasing the mRNA and protein expressions of FTH, TFR1, GPX4, and Nrf2 both in vivo and in vitro; and (3) the addition of DFO improved OTA-induced ferroptosis of grass carp primary myoblasts and promoted cell proliferation, while the addition of AKT improved OTA-inhibited myoblast differentiation and fusion, thus inhibiting muscle growth.

Vitamin D (VD) prevents bacterial infections and strengthens immune system function via vitamin D receptor (VDR). However, the correlation between VD/VDR and the structural integrity of functional organs remains unclarified.

In this study, we found LSD1 expression in metastatic gastric cancer tissues was significantly higher than that in normal tissues. Furthermore, LSD1 deletion was found to suppress gastric cancer migration by decreasing intracellular miR-142-5p, which further led to the upregulation of migration suppressor CD9, a newly identified target of miR-142-5p.
