The liver is responsible for the metabolism of the majority of currently utilized medicines and other foreign substances. Thioacetamide (TAA) is a potent hepatotoxin organosulfur compound. Moreover, TAA gained attention in research as a tool to induce liver injuries like inflammation, fibrosis, and cirrhosis, and to study liver regeneration.

: The present study aimed to evaluate the nephroprotective role of Khellin (Khe) against cisplatin (CDDP)-mediated nephrotoxicity in rats. : We assessed oxidative stress markers (MDA, CAT, SOD, GPx, and iNOs), inflammatory markers (TNFα, IL6, IL10, and MCP1), apoptotic markers (Bax and Bcl2), and the renal damage marker (Kim1). Network pharmacology and molecular docking studies were performed.

Autophagy is a vital cellular process that degrades and recycles intracellular components via lysosomes, playing a key role in maintaining cellular homeostasis. Alteration of this mechanism has been implicated in the occurrence and progression of numerous diseases, including cancer, neurodegenerative disorders, cardiovascular conditions, and microbial and viral infections. Recent studies have identified several mutations affecting autophagy-related genes and elucidated how defective degradation of specific substrates contributes to disease mechanisms.

Alcoholic liver disease (ALD) is a commonly known liver disease mediated by prolonged alcohol consumption. Aescin is a triterpene saponin that can manage several conditions, including brain trauma, arthritis, venous congestion, stroke, and thrombophlebitis. Even so, studies illustrating the aescin role in ALD are scarce.

Cisplatin is a potent compound in anti-tumor chemotherapy; however, its clinical utility is hampered by dose-limiting nephrotoxicity. This study investigated whether papaverine could mitigate cisplatin-induced kidney damage while preserving its chemotherapeutic efficacy. Integrative bioinformatics analysis predicted papaverine modulation of the mechanistic pathways related to cisplatin renal toxicity; notably, mitogen-activated protein kinase 1 (MAPK1) signaling.

Identifying new hepatocellular carcinoma (HCC)-driven signaling molecules and discovering their molecular mechanisms are crucial for efficient and better outcomes. Recently, OMA1 and YME1L, the inner mitochondrial proteases, were displayed to be associated with tumor progression in various cancers; however, their role in HCC has not yet been studied. Therefore, we evaluated the possible role of OMA1/YME1L in HCC staging and discussed their potential role in cellular apoptosis and proliferation.

Aims: Hepatocellular carcinoma (HCC) is considered one of the main causes of cancer-related death globally. Combination therapy targeting different pathways can improve the efficacy of HCC management. Mitofusin 2 (Mfn2), a mitochondrial fusion protein, and a tissue inhibitor of matrix metalloproteinase 3 (Timp-3) were found to be downregulated in various cancers, including HCC.

Matrix metalloproteinases (MMPs) or matrixins, are members of a zinc-dependent endopeptidase family. They cause remodeling of the extracellular matrix (ECM) leading to numerous diseases. MMPs subfamilies possess: collagenases, gelatinases, stromelysins and membrane-type MMPs (MT-MMP).

Hepatocellular carcinoma (HCC) is considered the most frequent tumor that associated with high mortality rate. Several risk factors contribute to the pathogenesis of HCC, such as chronic persistent infection with hepatitis C virus or hepatitis B virus, chronic untreated inflammation of liver with different etiology, oxidative stress and fatty liver disease. Several treatment protocols are used in the treatment of HCC but they also associated with diverse side effects.

Hepatocellular carcinoma (HCC), represents more than 85% of liver cancers. The diagnosis of HCC may be delayed due to the absence of early, sensitive and specific biomarkers. This study was conducted to investigate whether the expression of thioredoxin (Trx) and glutaredoxin (Grx) is helpful for HCC diagnosis in an experimental model.

This study was conducted to estimate the preventing and sensitizing efficiency of Alpinia officinarum rhizome extract (AORE) in an experimental model of hepatocellular carcinoma (HCC) +/- cisplatin. HCC was induced by a single intraperitoneal (i.p) dose of diethylnitrosamine (DENA, 200mg/kg).
