This study aims to investigate the mechanism of tanshinone Ⅱ_A(Tan Ⅱ_A) in protecting mice from diethylinitrosamine(DEN)/carbon tetrachloride(CCl_4)/ethanol(C_2H_5OH)-induced hepatocellular carcinoma(HCC) and HepG2 cells from hydrogen peroxide(H_2O_2)-induced oxidative damage via the phosphoinositide 3-kinase(PI3K)/protein kinase B(Akt) and nuclear factor E2-related factor 2(Nrf2)/heme oxygenase 1(HO-1) signaling pathways. Sixty male C57BL/6J mice were grouped as follows: control, model, low, medium, and high-dose(10, 20, 40 mg·kg~(-1), respectively) Tan Ⅱ_A, and colchicine(0.2 mg·kg~(-1)), with 10 mice in each group.

In China alone, HCC accounts for approximately 367,700 new cases and 316,500 deaths annually; over 50% of patients are diagnosed at an advanced stage, limiting curative treatment options and resulting in poor survival outcomes. Systemic therapies combining immune checkpoint inhibitors (ICIs) with antiangiogenic targeted drugs have shown promise in converting unresectable HCC into resectable cases, potentially transforming clinical outcomes.

Liver Disease Research Branch, Division of Digestive Diseases and Nutrition, National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), NIH, Bethesda, Maryland, USA.
Background And Aims: Short courses of intravenous (iv) methylprednisolone (MP) can cause drug induced liver injury (DILI). The aim of this study was to assess the clinical features and HLA associations of MP-related DILI enrolled in the US DILI Network (DILIN).
Methods: DILIN cases with MP as a suspected drug were reviewed.
Calpain 2 regulates IL-1α secretion and inhibits tumor development via modulating calpain 1 expression in the tumor microenvironment.

Tumor-promoting inflammation significantly impacts cancer progression, and targeting inflammatory cytokines has emerged as a promising therapeutic approach in clinical trials. Interleukin (IL)-1α, a member of the IL-1 cytokine family, plays a crucial role in both inflammation and carcinogenesis. How IL-1α is secreted in the tumor microenvironment has been poorly understood, and we previously showed that calpain 1 cleaves pro-IL-1α for mature IL-1α secretion, which exacerbates hepatocellular carcinoma by recruiting myeloid-derived suppressor cells.

Background And Aim: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths worldwide. Most patients are diagnosed at an advanced stage, limiting their treatment options. The traditional assessment of liver function using the Child-Pugh score has limitations due to its subjectivity.
