Objective: To investigate the anti-tumor effect of licochalcone A (LCA) on proliferation and migration in cholangiocarcinoma (CCA) cells and to elucidate their underlying mechanisms.
Methods: Human CCA cells, KKU-100, KKU-213, KKU-214, KKU-156, and KKU-452 were used to study effect of LCA on proliferation and migration by a cytotoxicity assay, wound healing assay. Reactive oxygen species levels were evaluated using DHE-fluorescent probes. Proteins associated with cancer survival and progression were analyzed by immune blotting assay.
Results: LCA suppressed proliferation and induced cell death in CCA cells including KKU-100, KKU-213, KKU-214, KKU-156, and KKU-452. The CCAs cells were suppressed in association with LCA-induced accumulation of intracellular reactive oxygen species (ROS). Increased formation of ROS was causally related with suppression of Nrf2 and its down-stream antioxidant and cytoprotective enzymes. These effects may lead to the expression of Bax and release of cytochrome c and ensuring cell death. Interestingly, LCA could also inhibit cell migration and cell cycle arrest at low concentrations. These effects were associated with down-regulation of NF-kB, STAT3 and their down-stream proteins, cyclin D1, VEGF, and ICAM-1.
Conclusions: These results suggest that LCA has potential therapeutic activity in suppression of CCA cells.

Persistent high-risk human papillomavirus (hHPV) infection, especially HPV-16, plays a central role in the development of high-grade squamous intraepithelial lesions (HSIL). This study aimed to evaluate the performance of co-testing (cytology and hHPV detection) in a real-world cohort of men who have sex with men (MSM) and transgender women (TW) living with HIV. We conducted a prospective study (2017-2023) at a tertiary care center in Spain.

Background: Late diagnosis and chemotherapy resistance, particularly to 5-fluorouracil (5-FU), contribute to the low survival rate in cholangiocarcinoma (CCA) patients. Identifying relevant genes and pathways, as well as novel targeted molecules, is crucial to overcoming 5-FU resistance and improving treatment outcomes for CCA patients.
Objectives: This study aimed to determine the potential molecules associated with 5-FU resistance in CCA cells.

Background: Cholangiocarcinoma (CCA) , an aggressive cancer often detected late, carries a grim prognosis. 2',4'-Dihydroxychalcone (2',4'-DHC), a flavonoid monomer isolated from Empetrum nigrum, has demonstrated notable anti-tumor activity in multiple cancer types. However, its therapeutic mechanism in cholangiocarcinoma remains poorly understood, especially regarding the regulation of ferroptosis, a mechanism that has not yet been fully elucidated in this disease.

Background: The aging problem is a significant issue and challenge currently faced by the whole world. Hyperhomocysteinemia (HHcy) is a common phenomenon among the older adult. Increasing evidence suggests a link between HHcy and multiple systemic issues in the older adult-related diseases.

Background/aim: Cholangiocarcinoma (CCA) is the second most frequently occurring primary malignant tumor of the liver, characterized by poor survival due to late diagnosis and limited treatment options. The albumin-bilirubin (ALBI) and platelet-ALBI (PALBI) scores, which reflect liver function and inflammation, have emerged as potential prognostic markers in hepatocellular carcinoma (HCC). Their prognostic significance in CCA, however, remains less established.
