Aim: This meta-analysis was conducted to evaluate the clinicopathological significance of Notch1 expression in patients with colorectal cancer (CRC).
Methods: Available articles were searched from diverse databases, and the meta-analysis was done by using Stata 12.0 software.
Results: Thirteen studies were included in this analysis (3401 samples). The Notch1 expression in CRC tissues was significantly higher than that in normal tissues statistically (OR: 15.46; 95% CI: 8.11-29.45; p = 0.003), and were associated with lymph node metastasis, tumor stage, depth of infiltration and histological differentiation.
Discussion: There is a close relationship between higher Notch1 expression in CRC. Notch1 may be involved in tumor progression, invasion and metastasis with CRC.
Conclusion: Notch1 overexpression in CRC suggested aggressive biological behaviors and thus implying that Notch1 may be a useful biomarker in CRCs.

Dihydromyricetin (Dih), a naturally occurring flavonoid, has been identified to exert a protective effect against ischemia/reperfusion injury. However, the detailed mechanisms remain unclear. Here we investigated the biological role of Dih in preventing hypoxia/reoxygenation (H/R) injury in cardiomyocytes.

6-PPDQ is a new type of environmental contaminant contained in tire rubber. No studies have been reported on the potential targets and mechanisms of action of 6-PPDQ on renal tissue damage. In the present study, we used CKD as an example to explore the potential targets and biological mechanisms of renal injury caused by 6-PPDQ using Network toxicology and animal experiments.

The Notch intracellular domain (NICD) regulates gene expression during development and homeostasis in a transcription factor complex that binds DNA either as monomer, or cooperatively as dimers. Mice expressing Notch dimerization-deficient (NDD) alleles of Notch1 and Notch2 have defects in multiple tissues that are sensitized to environmental insults. Here, we report that cardiac phenotypes and DSS (Dextran Sodium Sulfate) sensitivity in NDD mice can be ameliorated by housing mice under hypo-allergenic conditions (food/bedding).

Background: Intervertebral disc degeneration (IDD) is a leading cause of low back pain, often linked to inflammation and pyroptosis in nucleus pulposus (NP) cells. The role of Periostin (POSTN) in IDD remains unclear.
Objective: This study aims to investigate the influence of POSTN on pyroptosis and NLRP3 inflammasome activation in NP cells during IDD.

Objective: This study investigates the mechanism underlying sorafenib resistance in hepatocellular carcinoma cells (HCC), focusing on DNA damage repair (DDR) pathways to develop targeted therapeutic strategies.
Methods: Bioinformatics analysis was used to screen genes associated with sorafenib resistance, which was further demonstrated by western blotting. Cell proliferation was determined using the EdU assay.
