AI Article Synopsis
- This study investigates the relationship between the expression of the MKI67 proliferation marker and gene variants in patients with Hepatocellular carcinoma (HCC) associated with hepatitis B virus (HBV).
- Researchers analyzed data from 195 HCC patients and validated findings with 97 additional subjects, examining connections between MKI67, gene variants, and clinical outcomes.
- Results showed that certain genetic variants near the TTN and CCDC8 genes are linked to MKI67 expression and could serve as potential biomarkers for predicting HCC patient prognosis.
Article Abstract
Background/aims: Hepatocellular carcinoma (HCC) is a common malignant tumor with a high rate of recurrence. Immunohistochemical analysis of the marker of proliferation Ki-67 (MKI67) is used to assess proliferation activity of HCC The regulation of MKI67 expression remains unclear in HCC This study aims to explore the association between MKI67 expression and gene variants.
Methods: A total of 195 hepatitis B virus (HBV)-related HCC patients were genotyped using Illumina HumanExome BeadChip-12-1_A (242,901 markers). An independent cohort (97 subjects) validated the association of polymorphism determinants and candidate genes with MKI67 expression. The relationships between MKI67 with p53 and variants of candidate genes in the clinical outcomes of HCC patients were analyzed.
Results: We found that MKI67 combined with p53 was associated with a 3-year recurrence-free survival and five variants near TTN and CCDC8 were associated with MKI67 expression. TTN harboring rs2288563-TT and rs2562832-AA+CA indicated a favorable outcome for HCC patients.
Conclusion: Variants near TTN and CCDC8 were associated with MKI67 expression, and rs2288563 and rs2562832 in TTN are potential biomarkers for the prediction of clinical outcomes in HBV-related HCC patients.

Our recently created RNA-sequence-based microRNA (miRNA) expression signature in breast cancer clinical specimens revealed that some family members were significantly downregulated in cancer tissues. Based on TCGA database analyses, we observed that among the family members, (the passenger strand derived from pre-) was significantly downregulated in breast cancer (BC) clinical specimens, and its low expression predicted worse prognoses. Ectopic expression assays showed that transfected cancer cells (MDA-MB-157 and MDA-MB-231) had their aggressive phenotypes significantly suppressed, e.

There has been an increase in the incidence and poor prognosis of colorectal cancer in recent years. In several studies, piperine has been shown to inhibit colon cancer cell growth and induce apoptosis. This study aimed to investigate whether a novel piperine-derived compound, HJ-23 (2,2-difluorobenzo[d][1,3]dioxol-5-yl)(4-(2,4-difluorophenyl)piperazin-1-yl)methanone), can effectively inhibit the development of colorectal cancer through specific molecular mechanisms.

Tumor neovascularization mediated by endothelial cells (ECs) is essential for ovarian cancer (OC) progression, but interactions between epithelial cells and ECs are not well understood. Here, we analyze single-cell transcriptome of 87,847 epithelial cells and 11,696 ECs from fallopian tubes, primary and metastatic ovarian tumors. Cell differentiation trajectory analysis reveals that fallopian tube cells exhibit a potential development trend toward primary OC epithelial cells.

Purpose: Renal cell carcinoma (RCC), exhibiting remarkable heterogeneity, can be highly infiltrated by regulatory T cells (Tregs). However, the relationship between Treg and the heterogeneity of RCC remains to be explored.
Methods: We acquired single-cell RNA-seq profiles and 537 bulk RNA-seq profiles of TCGA-KIRC cohort.

Leucine-rich repeat-containing G protein-coupled receptors 5/4 (LGR5/LGR4) are critical stem cell markers in epithelial tissues including intestine. They agonise wingless-related integration site (WNT) signalling. Until now, LGR5/LGR4 were uncharacterised in placenta, where analogous functions may exist.
