Exposure to alcohol can induce different degrees of damage to various tissues and organs, and brain is the most vulnerable part affected by alcohol. However, there is no detailed report on whether intermittent alcohol exposure can result in pathological changes in the hypothalamus of adolescent rats and the detailed mechanism. This study investigated pathological changes in the hypothalamus, probed the levels of inflammatory factors, and detected the expression of proteins related to endoplasmic reticulum stress (ERS) to determine whether ERS is involved in the injury process of the hypothalamus and the protective mechanism of L-3-n-butylphthalide (L-NBP).

Cellular stress conditions, such as oxidative and endoplasmic reticulum (ER) stresses, contribute to the development of various kidney diseases. Oxidative stress is prompted by reactive oxygen species accumulation and delicately mitigated by glutathione and thioredoxin (Trx) antioxidant systems. Initially identified as a Trx-binding partner, Trx-interacting protein (TXNIP) is significantly up-regulated and activated by oxidative and ER stresses.

This study aims to investigate the effect and potential mechanism of Polygonati Rhizoma aqueous extract in protecting mice from gastric mucosal injury(stomach Yin deficiency). ICR mice were administrated with the mixture of pungent substance extract and alcohol by gavage once a day for 6 weeks to establish the mouse model of gastric mucosal injury with gastric Yin deficiency. The modeled mice were randomized into three groups of model and Polygonati Rhizoma aqueous extract administrated at 0.

Tubulointerstitial injury has been increasingly recognized as an important component in lupus nephritis (LN) pathology over the last decades. However, current clinical treatment options for this process remain limited. In this study, we aimed to investigate the potential benefits of GS-4997, a selective inhibitor of ASK1, in tubulointerstitial injury of LN.

Fish oocyte maturation (FOM) is a critical biological process that occurs before ovulation and is influenced by gonadotropins, particularly luteinizing hormone (LH). The release of LH stimulates the ovarian follicle to produce a maturation-inducing hormone (MIH), specifically 17α, 20β-dihydroxy-4-pregnen-3-one (17α, 20β-DP), which initiates the formation of maturation-promoting factor (MPF) through the activation of cyclin B and cdc2 kinase. Insulin-like growth factor I (IGF-I) significantly regulates ovarian functions, including steroidogenesis, by activating its membrane receptors and the tyrosine kinase pathway.
