Article Abstract
Hepatocellular carcinoma (HCC) is a major global public health concern, with approximately 79 million new cases and 75 million HCC-related deaths occurring annually worldwide. Among the drugs, cisplatin (DDP) is considered a cornerstone and has been shown to significantly inhibit cancer progression. However, the mechanism underlying DDP-resistance in HCC remains unclear. This study aimed to identify a novel lncRNA. FAM13A Antisense RNA 1 (FAM13A-AS1), that promotes the proliferation of DDP-resistant HCC cells and to elucidate its downstream and upstream mechanisms in the progression of HCC DDP-resistance. Our results suggest that FAM13A-AS1 interacts directly with Peroxisome Proliferator Activated Receptor γ (PPARγ), stabilizing its protein through de-ubiquitination. Moreover, our findings indicate that Paired Like Homeobox 2B (PHOX2B) transcriptionally regulates the expression of FAM13A-AS1 in HCC cells. These results shed new light on the understanding of the progression of HCC DDP-resistance.

Chronic liver disease (CLD) is a leading cause of global morbidity and mortality, necessitating effective preventive strategies. Growing evidence is linking coffee consumption with reduced risk of disease progression in various CLDs, including metabolic dysfunction associated steatotic liver disease (MASLD), alcoholic liver disease, hepatitis B and C, autoimmune hepatitis, and a reduction in the risk of hepatocellular carcinoma development. Coffee, a globally consumed beverage, contains bioactive compounds like caffeine, chlorogenic acids, diterpenes, and polyphenols, which may offer hepatoprotective benefits through anti-inflammatory, antioxidant, and metabolic regulatory effects.

Background: Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths, primarily due to late-stage diagnosis. In this multicenter study, our goal is to identify functional biomarkers that stratify the risk of HCC in patients with cirrhosis (CP) for early diagnosis.
Methods: Five thousand and eight serum proteins (Somascan) were analysed in Cohort A (477 CP, including 125 HCC).

TP53 mutations are highly associated with hepatocellular carcinoma (HCC), a common and deadly cancer. However, few primary drivers in the progression of HCC with mutant TP53 have been identified. To uncover tumor suppressors in human HCC, a genome-wide CRISPR/Cas9-based screening of primary human hepatocytes with MYC and TP53 overexpression (MT-PHHs) is performed in xenografts.
