Assembly and penetration of 14-strand beta-barrel of staphylococcal alpha-hemolysin (alpha-HL) is an intriguing phenomenon due to its water soluble property. alpha-HL interacts with the Caveolin-1 of A431 cells for its rapid assembly. A nine amino acid, non-hydrophobic peptide derived from alpha-HL has been shown to block the interaction of alpha-HL with the scaffolding domain of Caveolin-1. alpha-HL's presence was also detected in the Caveolin-1 enriched membrane fractions isolated by ultracentrifugation. Moreover, alpha-HL co-precipitates with Caveolin-1 specifically. In a time-dependent process, alpha-HL associates with the Caveolin-1 and co-localizes with Caveolin-1 that results in an extensive clustering of Caveolin-1 at cell-cell contacts. Mutants of alpha-HL devoid of Caveolin-1 binding motif failed to assemble into heptameric oligomers on the surface of A431 cells. Our data suggest that the conformational changes required to form the heptameric assembly might be triggered at the Caveolin-1 binding motif of alpha-HL.
Effective treatment of squamous cell carcinoma (SCC) poses challenges due to intrinsic drug resistance and limited drug penetration into tumor cells. Nanoparticle-based drug delivery systems have emerged as a promising approach to enhance therapeutic efficacy; however, they often face hurdles such as inadequate cellular uptake and rapid lysosomal degradation. This study explores the potential of iontophoresis to augment the efficacy of liposome and immunoliposome-based drug delivery systems for SCC treatment.
Cutaneous squamous cell carcinoma (cSCC) is a common type of cutaneous cancer globally. M2 macrophage-derived exosomes (M2 exosomes) facilitate the development of cancer. Ferroptosis, a newly uncovered form of cell death, is linked to cancer progression.
Introduction: Cancer has emerged as one of the leading causes of fatality all over the world. Phytoconstituents are being studied for their synergistic effects, which include disease prevention by altering molecular pathways and immunomodulation without side effects. The present experiment aims to explore the cancer preventive activities of Linn leaves extract in skin cancer cell lines (A431) and colon cancer cell lines (COLO 320DM)).
The current study proposes the in vitro and in silico anticancer evaluation of clove ( L.) essential oil (CEO). The steam hydrodistillation method used yielded 10.
Sun persuades excess ROS production in the skin, altering pro-inflammatory factors and cellular responses, thereby contributing to the progression of skin disorders and skin cancer. In this study, the non-animal, and methods have been employed to interpret the potential of bioactive mangiferin against skin inflammation and skin cancer. In the approach, auto blind docking tool CB Dock 2 was utilized to assess and compare the efficacy of mangiferin against some conventional drugs like aspirin, diclofenac, betamethasone for inflammation and with 5-fluorouracil, docetaxel, doxorubicin, imiquimod, paclitaxel, sonidegib, vincristine and vismodegib for skin cancer.
