Increasing studies suggest that autophagy has a protective role in cancer treatment and may even be involved in chemotherapy resistance. Nevertheless, the mechanism of autophagy in cancer treatment and drug resistance has not yet been established. There is a complex association between autophagy and apoptosis. Accordingly, these two processes can mutually regulate and transform to determine the fate of a cell, depending on the context. Activating molecule in Beclin 1-regulated autophagy protein 1 (Ambra1) is an important factor at the crossroad between autophagy and apoptosis. The expression level and intracellular distributions of Ambra1 may control the balance and conversion between autophagy and apoptosis, and modify the effectiveness of chemotherapy. Therefore, Ambra1 may provide a novel target for cancer treatment, particularly for overcoming anticancer drug resistance. The present review focuses on the role of Ambra1 in autophagy and apoptosis and assesses the implications for cell survival and chemotherapy resistance.

To investigate the role of silent information regulator 6 (SIRT6) in regulating podocyte injury in diabetic nephropathy (DN) through autophagy mediated by Notch signaling pathway. A blank control group (group A), a diabetic nephropathy group (group B), and a Sirt6 intervention group (group C) were established. The group A cells were human normal glomerular podocyte cell lines (HGPCs) without any treatment.

Background: Naringenin, a flavonoid compound found in citrus fruits, possesses valuable anticancer properties. However, its potential application in cancer treatment is limited by poor bioavailability and pharmacokinetics at tumor sites. To address this, Naringenin nanoparticles (NARNPs) were prepared using the emulsion diffusion technique and their anticancer effects were investigated in HepG2 cells.

Purpose: Preimplantation aneuploidy in humans is one of the primary causes of implantation failure and embryo miscarriage. This study was conducted to gain insight into gene expression changes that may result from aneuploidy in blastocysts through RNA-Seq analysis.
Methods: The surplus embryos of preimplantation genetic testing for aneuploidy (PGT-A) candidate couples with normal karyotype and maternal age < 38 were collected following identical ovarian stimulation protocol.

Cervical cancer (CC) is becoming a major health issue globally, and radiotherapy plays a crucial role in its treatment. However, the prognosis of some patients remains poor due to tumor resistance to the therapy. This study aimed to explore whether vitamin D could confer a more radiosensitive phenotype in CC based on our previous findings and detection using the database.
