Female germline stem cells (FGSCs) are adult stem cells capable of self-renewal and differentiation into mature oocytes. AKT3, a member of the AKT kinase family, plays crucial roles in multiple cellular processes, such as proliferation, migration, and apoptosis. However, the mechanism by which AKT3 affects the development of FGSCs is poorly understood.

Extensive research has been carried out on few-layered MoS in the field of electrochemistry due to its large specific surface area, abundant active sites and short electron transport path. However, the preparation of few-layered MoS is a significant challenge.

Hesperidin is one of the main active ingredients of (Rutaceae) and tangerine peel, which have anti-inflammatory and antioxidant effects. In previous study, we found that gastric motility disorder in functional dyspepsia (FD) rats accompanied by excessive autophagy/mitochondrial swelling and even vacuolization in the interstitial cells of cajal (ICC), but the exact mechanism has not yet been investigated. Therefore, we used different doses of hesperidin (50 mg/kg, 100 mg/kg, and 200 mg/kg) to intervene in FD rats, and found that medium doses of hesperidin (100 mg/kg) significantly increased gastric motility in FD rats.

However, there are no specific drugs for these conditions. Although many studies have shown that traditional Chinese medicine is effective with no serious side effects, these studies have not been scientifically rigorous trials.

The BuShen JiangZhi (BSJZ) recipe is a Chinese medicine compound with the effect of tonifying the kidney, replenishing essence, and lowering blood fat to unblock vessels. The purpose of this study is to explore whether the mechanism of BSJZ for effective intervention in the treatment of AS is related to mmu_circRNA_22187 and aminopeptidase N (Anpep). ApoE mice were induced by a high-fat diet to replicate the AS model.

Objective: To study the effect of Bushen Jiangzhi formula (BSJZF) on atherosclerosis (AS) in apolipoprotein E knockout (apoE-/-) mice and the underlying mechanism.
Methods: We used a high fat diet to induce AS in apoE-/- mice. The mice were randomly divided into four groups: model, BSJZF, atorvastatin, and 3-methyladenine groups.
Objective: To evaluate the efficacy of Shoushen granule, prepared with four Chinese medicinals, on the targeted regulation of adenosine triphosphate binding cassette transporter A1 (ABCA1) through proprotein convertase subtilisin/kexin type 9 (PCSK9) and toll-like receptor 4 (TLR4) / nuclear factor kappa-B (NF-κB) signaling pathway to affect atherosclerosis (AS) in ApoE-knockout (ApoE-/-) mice.
Methods: ApoE-/- mice fed with a high-fat diet were used for AS modeling and divided into Model, Shoushen, and Atorvastatin groups. C57BL/6J mice at the same age and background strain were included in the Control group.
Objective: To investigate the process by which quercetin suppresses atherosclerosis by upregulating MST1-mediated autophagy in RAW264.7 macrophages.
Methods: An in vitro foam cell model was established by culturing RAW264.
To test the hypothesis that the flavonoid compound, fisetin, protects macrophages from lipid accumulation and senescence through regulation of casein kinase 2-interacting protein-1 (CKIP-1)/REGγ (11S regulatory particles, 28 kDa proteasome activator, proteasome activator subunit 3) signaling. RAW264.7 macrophage cells were exposed to 100 μg/ml oxidized low-density lipoprotein (ox-LDL) with or without 20 μg/ml fisetin for 24 h.
