The AKT pathway serves important roles in tumor cell growth. Its overexpression is associated with poor prognosis in a number of types of cancer; however, the role of AKT in the role of the pathogenesis of hepatocellular carcinoma (HCC) remains unclear. The present study was undertaken to explore the clinical relevance of phosphorylated AKT (p-AKT) in HCC. The level of p-AKT in tumor (TU) and paired adjacent normal liver (AN) tissue from 202 HCC patients was evaluated with immunohistochemistry. The results demonstrated that p-AKT was more highly expressed in TU than in AN tissue. Kaplan-Meier curves and Cox regression revealed that patients with a high expression of p-AKT (AN) exhibited reduced overall and relapse-free survival times; this was not observed at a statistically significant level in p-AKT (TU). Additionally, the high expression of p-AKT (AN) was positively correlated with hepatitis C virus (HCV) infection in HCC patients. These results support the hypothesis that AKT activation is a mechanism of HCV-induced hepatocarcinogenesis, suggesting that AKT can be a therapeutic target for the treatment of recurrent HCC subsequent to surgical resection.

Background: Mutations in the structural domain of the epidermal growth factor receptor (EGFR) kinase represent a critical pathogenetic factor in non-small cell lung cancer (NSCLC). Small-molecule EGFR-tyrosine kinase inhibitors (TKIs) serve as first-line therapeutic agents for the treatment of EGFR-mutated NSCLC. But the resistance mutations of EGFR restrict the clinical application of EGFR-TKIs.

Brain aging is the leading risk factor for most neurodegenerative diseases and has been linked with high rates of neuron loss. Thus, identifying molecular mechanisms underlying neuron loss and pharmacological modulation may be of great importance for slowing or preventing age-related diseases. Herein, we investigated the roles of miR-92a, Akt, mTOR, and NF-κB in age-associated apoptosis in the hippocampus (a critical structure involved in brain aging) of male rats alone and in combination with prazosin.

Andrographis paniculata (AGPA) is known for its wide-ranging biological activities, including antiviral, antipyretic, and anticancer properties. However, its effects on muscle atrophy have not been well understood. This study investigates the impact of andrographolide (AD) and dehydroandrographolide succinate (DAS), key components of AGPA, on skeletal muscle atrophy using in vitro and in vivo models.

Spermatozoa must undergo a complex maturation process within the female genital tract known as capacitation. This process entails the phosphorylation or dephosphorylation of various proteins, and multiple signaling pathways are recognized to play a role. The present study aims to identify alterations in the expression of proteins related to the phosphatidylinositol-3 kinase (PI3K)/protein kinase B (AKT) signaling pathway and assess sperm functions during capacitation.

Bisphenol A (BPA), an environmental endocrine disrupting chemical, is one of the most widely used chemicals in the world and is widely distributed in the external environment, specifically in food, water, dust, and soil. BPA exposure is associated with abnormal cognitive behaviors. However, the underlying mechanism remains unclear.
