The study focuses on the role of HIC1 (Hypermethylated in cancer 1) in PCa, revealing its downregulation in PCa tissues compared to normal counterparts. Using transcriptome sequencing and bioinformatics, it was found that HIC1 influences key cellular processes like cell growth, proliferation, invasion, and androgen receptor (AR) signaling in PCa. Specifically, AR was identified as a transcription factor for insulin receptor substrate 2 (IRS2), which activates the PI3K/AKT pathway, enhancing PCa cell proliferation and invasion. However, this effect could be reversed by IRS2 inhibition using NT157. Furthermore, HIC1 overexpression reduced castration resistance in PCa cells, with in vivo studies showing that HIC1 silencing increased PCa xenograft growth and resistance, and elevated Ki-67, Cleaved-caspase-3, EMT markers, and prostate-specific antigen (PSA) levels. Conversely, AR and IRS2 inhibitors like EPI-7170 and NT157 negatively affected PCa progression.

NETs were predominantly initiated by hypoxia/reoxygenation (H/R) in endothelial cells (ECs), rather than in neutrophils. Silencing Fpn1 in ECs significantly reduced extracellular iron, suppressed ROS production, and inhibited NETs formation—effects that were reversed by supplementation with iron or hemin. Additionally, both vitamin C (Vc) and deferoxamine (DFOM) suppressed blood coagulation on Fpn1-silenced ECs under H/R conditions. NETs formation on hypoxic ECs was further enhanced in the presence of co-cultured red blood cells. In a mouse model of middle cerebral artery occlusion, combined treatment with Vc and DFOM synergistically reduced infarct size. Although Vc or DFOM alone reduced NETs formation, their combined use showed a weaker effect than DFOM alone, possibly because better blood flow increased neutrophil contact with the endothelium.

Functional validation through Tp53 overexpression and Cdkn1a/Myc knockout in mice demonstrated their critical roles in exacerbating myopia phenotypes, including elongated eye axis and thickened retina. These findings highlight a synergistic interplay between cellular senescence and immune-mediated mechanisms in myopia, supported by multi-omics evidence and in vivo experiments.

Functional validation was conducted through RT-qPCR, dual-luciferase reporter assays, methylation-specific PCR, chromatin immunoprecipitation, and phenotypic assays in ZR-75-1 cells.

Elevated TSHZ2 inhibited Hedgehog-GLI signaling, thereby reducing cell proliferation, migration, invasion, and tumorigenic potential. Reintroduction of DNMT1 or activation of Hedgehog-GLI signaling reversed these effects. In vivo, miR-217 overexpression suppressed tumor growth, downregulated DNMT1 and GLI1, and increased apoptosis.
