Anti-apoptotic proteins such as BCL-2, BCL-XL and MCL-1 bind with pro-apoptotic proteins to induce apoptosis mechanism. BCL-2 family proteins are key regulators of apoptosis process. Over expression of these anti-apoptotic proteins lead to several cancers by preventing apoptosis. A number of studies revealed that ginseng derivatives reduce tumor growth. Ginseng, the most valuable medicinal herb found in eastern Asia belongs to Araliaceae family. In this study, docking simulations were performed for anti-apoptotic proteins with several ginsenosides from Panax ginseng. Our finding shows ginsenosides Rf, Rg1, Rg3 and Rh2 have more binding affinity with BCL-2, BCL-XL and MCL-1 and other ginsenosides also interact with each anti-apoptotic proteins. Therefore, ginseng derivatives represent a novel class of potent inhibitors and could be used for cancer chemotherapy.

Department of Knee Surgery, The First Hospital of Hebei Medical University, Hebei, China.
Objective: This study aims to explore the potential role of mesenchymal stem cells (MSCs) in the treatment of osteoarthritis (OA), particularly the function of the NOTCH1 signaling pathway in maintaining the stemness of MSCs and in chondrocyte differentiation.
Methods: Utilizing diverse analytical techniques on an osteoarthritis dataset, we unveil distinct gene expression patterns and regulatory relationships, shedding light on potential mechanisms underlying the disease. Techniques used include the culture of MSCs, induction of differentiation into chondrocytes, establishment of stable cell lines, Western Blot, and immunofluorescence.

Spinal cord injury (SCI) is a common neurological trauma that cannot be completely cured with surgical techniques and medications. In this study, we established a mouse SCI model and used an adeno-associated virus (AAV) to achieve the high expression of sonic hedgehog (Shh) at the injury site to further investigate the therapeutic effect and mechanism of Shh on SCI. The results of the present study show that Shh may promote motor function recovery.

Background: Various investigations have elucidated the impact of diet and environmental toxins on the aging process. Melamine (Mel) is a widely recognized and infamous food adulterant with documented toxicity in various organs, including the brain. Nevertheless, there is currently a dearth of reports on the neurotoxic effects of Mel in aging neurons.

Background: Stroke and AD patients with gut complications often present worsened neurological outcomes. The goal of this study was to examine the role of extracellular vesicle (EV)-mediated pyroptosis in the bi-directional gut-brain axis after photothrombotic stroke (PTS) in aged 3xTg mice and wildtype (WT) controls.
Method: Twelve-month 3xTg and WT male and female mice underwent PTS using a YAG laser.
