Thyroid hormones (THs) are essential for normal development of the mammalian central nervous system through regulation of TH-responsive genes. EphA5, an important TH-responsive gene encoding the tyrosine kinase receptor EphA5, regulates synaptogenesis initiation and synaptic remodeling during brain development. Abnormal EphA5 expression is involved in the development of congenital hypothyroidism (CH). To show the regulatory mechanism of EphA5 expression in CH rats, we analyzed the correlation between methylation of the EphA5 promoter and its expression in the hypothyroid hippocampus and hippocampal neurons. Demethylation treatment using 5'-azadeoxycytidine upregulated EphA5 expression and rescued the effects of hypermethylation, suggesting a novel regulatory mechanism of EphA5 expression in CH rats. Our results suggest a potentially new approach for the development of drugs to restore neurocognitive impairments associated with CH.

To investigate the immunophenotypic and molecular biological characteristics of patients with elevated serum alpha-fetoprotein (AFP) and enteroblastic differentiated gastric adenocarcinoma (GAED). The clinicopathological data of 13 patients with elevated serum AFP and GAED admitted to Shanxi Cancer Hospital from 2018 to 2020 were collected. Immunohistochemistry (IHC) and next-generation sequencing (NGS) were used to analyze the immune markers and molecular biological characteristics of the pathological tissues of the patients.

Background: Erythropoietin-producing human hepatocellular (Eph) receptors stand out as the most expansive group of receptor tyrosine kinases (RTKs). Accumulating evidence suggests that within this expansive family, the EphA subset is implicated in driving cancer cell progression, proliferation, invasion, and metastasis, making it a promising target for anticancer treatment. Nonetheless, the extent of EphA family involvement across diverse cancers, along with its intricate interplay with immunity and the tumor microenvironment (TME), remains to be fully illuminated.

Cervical cancer is one of the most frequent cancers in women and is associated with human papillomavirus (HPV) in 70 % of cases. Cervical cancer occurs because of progression of low-differentiated cervical intraepithelial neoplasia through grade 2 and 3 lesions. Along with the protein-coding genes, long noncoding RNAs (lncRNAs) play an important role in the development of malignant cell transformation.
