Yet, less is known about another hotspot p53 mutant, R249S (p53-R249S). p53-R249S is the sole hotspot mutation in hepatocellular carcinoma (HCC) that is highly associated with chronic hepatitis B virus (HBV) infection and dietary exposure to aflatoxin B1 (AFB1).
PRLH1 is highly expressed in p53-mutated hepatocellular carcinoma (HCC) samples and promotes cell proliferation in p53-mutated HCC cells, and its transcription is promoted by NF-Y and suppressed by p53.
Furthermore, we observe that Nup155 and FTSJ1 are p53 repression targets and accordingly find a correlation between the p53 status, Nup155 and FTSJ1 expression in murine and human hepatocellular carcinoma.
Moreover, the cytotoxic activity of C3 was examined in two other hepatocellular carcinoma (HCC) cell lines with different p53 status including Huh-7 cells (p53-mutant) and Hep3B cells (p53-null).
This study investigated the efficacy of Toxoplasma GRA16, which binds to herpes virus-associated ubiquitin-specific protease (HAUSP), in anticancer treatment, and whether the expression of GRA16 in genetically modified hepatocellular carcinoma (HCC) cells (GRA16-p53-wild HepG2 and GRA16-p53-null Hep3B) regulates PTEN because alterations in phosphatase and tensin homologue (PTEN) and p53 are vital in liver carcinogenesis and the abnormal p53 gene appears in HCC.
Western blot results showed that the knockdown of PSMD4 blocked the expression of cyclooxygenase 2 (COX2), phosphorylated Sarcoma tyrosine kinase (P-SRC) and Bcl-2, but improved the levels of p53 and Bax in HCC, lung cancer, colorectal cancer, breast cancer and endometrial cancer cell lines.
We identified 5 genes (WNK2, RUNX1T1, CTNNB1, TSC1, and TP53) harboring somatic mutations that correlated with early tumor recurrence after curative resection in 182 primary HCC samples.
Majority of AFB1 associated hepatocellular cancer cases carry TP53 mutant DNA, which is an indicator of AFB1 exposure, as well as hepatocellular cancer risk.
Quercetin, an antioxidant flavonoid, has been known that it can induce the cell cycle arrest and apoptosis of hepatocellular carcinoma (HCC) cells by the stabilization or induction of p53.
The Na+/K+‑ATPase inhibitor cinobufagin exhibits numerous anticancer effects on hepatocellular carcinoma (HCC) cells expressing wild‑type p53 via inhibition of aurora kinase A (AURKA) and activation of p53 signaling.
We searched for pathogenic variants in TP53 in a 14 year-old female diagnosed with fibrolamellar hepatocellular carcinoma, a rare subtype of hepatocellular carcinoma.
The GSEA revealed that PON1 was associated with several hepatocellular carcinoma-related pathways, including the cell cycle, DNA replication, gap junction and p53 downstream pathways.
Here we found that suppressing TIP60 inhibited p53 K120 acetylation and thus rescued apoptosis induced by glucose deprivation in hepatocellular cancer cells.
Moreover, recent researches reported increasing pathways and mechanisms related to ferroptosis in HCC such as TP53 and Rb, and strategies to improve sorafenib resistance by targeting ferroptosis.
