Article Synopsis
  • * A study using murine models showed that the presence of the Nef protein in HIV increases neuroinflammation and damages brain structures compared to Nef-deficient strains.
  • * Findings suggest that Nef plays a key role in worsening neuronal injury and may guide future research on HAND mechanisms and treatments.

Background: Alcohol consumption, depression, and chronic diarrhea are all public health issues of concern, with irreversible consequences for individual health and significant economic burdens on health care systems. Previous studies have shown that depression increases the risk of developing chronic diarrhea, but few studies have explored whether alcohol consumption has an effect on the relationship between depression and chronic diarrhea.

Objective: To explore the effect of alcohol consumption on the relationship between depression and chronic diarrhea.

Manganese (Mn) plays an essential role in plant growth; however, excessive Mn is toxic to plants. Polygonum lapathifolium Linn. was tested as a novel Mn-hyperaccumulating species in our previous study, but the underlying mechanisms of this hyperaccumulation are poorly understood.

Chemoresistance limits cisplatin (DDP)-mediated treatment for gastric cancer (GC). Circular RNA (circRNA) acts an important role in chemoresistance. However, the underlying mechanism of circPDSS1 regulating DDP sensitivity in GC remains unclear.

Background And Objectives: Diets containing red or processed meat are associated with a growing risk of digestive system cancers. Whether a plant-based diet is protective against cancer needs a high level of statistical evidence.

Methods: We performed a meta-analysis of five English databases, including PubMed, Medline, Embase, Web of Science databases, and Scopus, on October 24, 2021 to identify published papers.

Article Synopsis
  • Multidrug resistance in tumors leads to recurrence and spread, prompting research into its mechanisms and treatments, specifically in SW480 colon cancer cells.
  • Exosomes from drug-resistant SW480/oxaliplatin cells enhanced the growth, movement, and tube formation of human endothelial cells, with significantly higher BMP-2 expression compared to sensitive cells.
  • The study suggests that exosomal BMP-2 promotes angiogenesis through the BMP-2/Smad signaling pathway, offering a potential target for new antiangiogenic therapies in colon cancer.

Cisplatin-based chemotherapy and radiotherapy are the main first-line treatment strategies for nasopharyngeal carcinoma (NPC) patients. Unfortunately, resistance is a major obstacle in the clinical management of NPC patients. We prove that the expression level of high-mobility group box 1 (HMGB1) is dramatically increased in resistant NPC cells than that in sensitive cells.

Article Synopsis
  • The polycomb repressive complex 2 (PRC2), particularly its component EZH2, is crucial for keeping certain genes turned off, and its dysregulation is linked to cancer development, especially in B-cell lymphomas.
  • In mantle cell lymphoma (MCL), PRC2 components are found to be heavily upregulated, leading to enhanced cell growth and survival, despite the absence of EZH2 mutations in this subtype.
  • Pharmacological inhibition of EZH2 effectively slows down MCL cell growth by disrupting the suppressive epigenetic marks it creates, suggesting that EZH2 inhibitors could be a promising treatment for MCL patients.

The present studies have identified that microRNAs function as regulators in different diseases including cancers. However, the expression patterns and underlying molecular mechanisms of miR-208a involved in gastric cancer (GC) remain little known. In the study, our results demonstrated that miR-208a expression was significantly increased in GC tissues compared with adjacent normal tissues by performing qRT-PCR.

In recent years, phytoestrogens have been shown as useful selective estrogen receptor modulators. The estrogen-like effects of black tea (BT) and D. candidum (DC), as well as the combination of the two herbs, have remained largely elusive.

Erianin is a natural product extracted from Dendrobiumchrysotoxum. To investigate the antitumor activity of Erianin in estrogen receptor (ER) positive breast cancer, we treated T47D cells with Erianin and evaluated the effects of Erianin treatment on multiple cancer-associated pathways. Erianin inhibited the proliferation of T47D cells effectively.

The dynamic and reversed expression of GATA1 and GATA2 are essential for proper erythroid differentiation. Our previous work demonstrates that LSD1, a histone H3K4 demethylase, represses GATA2 expression at late stage of erythroid differentiation. K562 and MEL cells were used and cultured in Roswell Park Memorial Institute-1640 medium (RPMI) and Dulbecco's modified Eagle's medium (DMEM), respectively.

Article Synopsis
  • Honokiol, derived from Magnolia bark, shows potential in lowering blood sugar levels in a mouse model of type 2 diabetes by enhancing insulin signaling pathways.
  • The study demonstrated that honokiol treatment led to significant decreases in fasting blood glucose and increased activation of key proteins involved in insulin signaling, such as the insulin receptor and AKT.
  • Additionally, honokiol inhibits the protein tyrosine phosphatase 1B (PTP1B), which plays a role in insulin resistance, suggesting its therapeutic potential for managing diabetes.

Protein tyrosine phosphatase 1B (PTP1B) is an established therapeutic target for type 2 diabetes mellitus (T2DM) and obesity. The aim of this study was to investigate the inhibitory activity of Magnolia officinalis extract (ME) on PTP1B and its anti-T2DM effects. Inhibition assays and inhibition kinetics of ME were performed in vitro.

Protein tyrosine phosphatases (PTPs) are enzymes that catalyze protein tyrosine dephosphorylation of which Src homology phosphatase-1 (SHP-1) is one of the best-validated, a widely distributed intracellular tyrosine phosphatase that contains two SH2 domains. Down regulation of SHP-1 tyrosine phosphatases was significantly increased sensitivity to insulin in insulin signaling pathway. Through in vitro enzymatic reaction kinetics experiment, we found that the extract of Perilla stem was a potential inhibitor to δSHP-1, the catalytic domain of SHP-1 protein tyrosine phosphatase, and its IC(50) was 4ug/ml, and was more sensitive towards SHP-1than other PTPs, which indicated that SHP-1 might be a target of the extract of Perilla stem.
