Purpose: Primary surgery failure of macular holes causes poor visual acuity outcomes. Several studies indicate that small-medium idiopathic full-thickness macular holes (iFTMH) have consistent and high anatomical closure rates after vitrectomy and internal limiting membrane (ILM) peeling, regardless of iFTMH diameters. However, there is no systematic analysis examining the relationship between iFTMH diameters and anatomical closure rates.

Objective: To study the expression of the Homeobox C6 (HOXC6) gene in the homeobox family in PCa, its effect on the biological behavior of PCa cells and its action mechanism.

Methods: Based on the studies of HOXC6 retrieved from the database of Gene Expression Profiling Interactive Analysis (GEPIA), we analyzed the expression of HOXC6 in PCa and the relationship of its expression level with the survival prognosis of the patients. We detected the expression of the HOXC6 protein in PCa tissues and cells by Western blot, stably interfered with the expression of the HOXC6 gene in human PCa DU145 and PC-3 cells and normal prostatic epithelial RWPE-1 cells using the siRNA plasmid, and determined the effects of HOXC6 on the proliferation, migration and invasiveness of PCa cells by CCK8, plate cloning and scratch healing and Transwell invasion assays.

Article Synopsis
  • High levels of high-density lipoprotein cholesterol (HDL-C) are linked to higher mortality, especially in individuals with hypertension, according to a study of nearly 430,000 participants from the UK Biobank.
  • The study found a U-shaped relationship between HDL-C and mortality in those with hypertension, meaning very high HDL-C levels (>90 mg/dL) significantly increase the death risk, while a different L-shaped pattern was seen in those without hypertension.
  • Additionally, the size of HDL particles (HDL-P) influenced mortality risk, with larger HDL-P correlating to increased risk in hypertensive individuals, making the association between HDL-C and mortality more complex.
