Article Abstract
Pterygium is a common eye surface disease with high recurrence and unclear pathogenesis. In current study, RNA sequencing was conducted in 6 pairs of human pterygium and conjunctival tissues, and Matr3 as a novel candidate gene was significantly reduced in pterygium compared to control tissues. Moreover, immunoprecipitation was performed to pull down MATR3, and WTAP specially interacting with MATR3 in control but not pterygium was identified by mass spectrum. Immunoprecipitation was performed to validate the interaction between MATR3 and WTAP/METTL3/METTL14 complex. (Methylated) RNA immunoprecipitation was performed to further reveal that the binding affinity of WTAP and MATR3 was lost at 3' UTR of RNA molecules of down-regulated genes in pterygium. Overall, we figured out the loss of intercrossing between MATR3 and N6-methyladenosine methyltransferase complex, as well as indicated the potential impact on transcription of target genes in pterygium.

PPM1D is directly degraded by proteasomes in a ubiquitination-independent manner through its carboxyl-terminal region.

Background: PPM1D (protein phosphatase Mg⁺/Mn⁺ dependent 1D) is a Ser/Thr phosphatase that negatively regulates p53 and functions as an oncogenic driver. Its gene amplification and overexpression are frequently observed in various malignancies and disruption of PPM1D degradation has also been reported as a cause of cancer progression. However, the precise mechanisms regulating PPM1D stability remain to be elucidated.

Purpose: The fourth most common cause of cancer-related deaths in women is cervical cancer. Though treatment of early-stage cervical cancer is often effective, middle and advanced stage cervical cancer is hard to treat and prone to recurrence. We sought to explore the mechanism underlying cervical cancer progression to identify new therapeutic approaches.

Purpose: This study aimed to elaborate the mechanism of cuproptosis induced by HO in ulcerative colitis (UC).
Methods: Bioinformatics based on GSE107499, GSE87466, and GSE92415 datasets was performed to screen hub genes related to cuproptosis. In vitro, cell counting kit 8 (CCK8), flow cytometry were applied for detecting cell proliferation and apoptosis.

Introduction: Epigenetic changes are important modulators of gene expression. The histone acetyltransferase gene non-derepressible 5 (Gcn5) is emerging as a pivotal epigenetic player in metabolism and cancer, yet its role in obesity and cardiovascular disease remains elusive.
Aims: To investigate Gcn5 role in obesity-related endothelial dysfunction.
Hepatitis B virus (HBV) precore G1896A mutation is closely associated with poor prognosis of liver disease. We previously revealed that the G1896A mutation could enhance HBV replication and promote hepatocellular carcinoma (HCC) cell growth both in vitro and in vivo. However, the in-depth mechanisms by which this mutation promotes the malignancy of HCC still need to be explored.
