Resveratrol, a natural product with a stilbene structure, exerts profound proapoptotic activity in human cancer cells, by triggering the accumulation of ceramide, a bioactive sphingolipid. We studied the biological effects of seven methoxylated and/or naphthalene-based resveratrol analogues and compared these compounds with resveratrol with the objective to identify an analogue with higher ceramide-mediated proapoptotic activity relative to resveratrol. Here we show that the compound with three hydroxyls and a naphthalene ring is the most effective in triggering apoptosis coupled to the induction of endogenous ceramide in human cancer cells.

Background: Inadequate treatment responses, chemotherapy resistance, significant heterogeneity, and lengthy treatment durations create an urgent need for new pancreatic cancer therapies. This study aims to investigate the effectiveness of gemcitabine-loaded nanoparticles enclosed in an organo-metallic framework under ketogenic conditions in inhibiting the growth of MIA-PaCa-2 cells.
Methods: Gemcitabine was encapsulated in Metal-organic frameworks (MOFs) and its morphology and size distribution were examined using transmission electron microscopy (TEM) and Dynamic light scattering (DLS) with further characterization including FTIR analysis.

PP2C serine-threonine phosphatase Wip1 plays an important role in normal tissue homeostasis, stress signaling and pathogenesis of various human diseases. It is an attractive drug target for cancer treatment and inhibition of its expression or activity constitute a novel therapeutic intervention strategy to prevent the development of various cancers. However, previous strategies for Wip1 suppression may be ineffective in cancers lacking p53.

Exposure to UV irradiation results in abnormal, extensive apoptosis of skin cells. This excessive cell death can promote inflammation and alter the microenvironment, increasing the risk of skin cancer. Despite extensive research, few materials are effective at simultaneously protecting against both UVA and UVB irradiation.

Background: Carnosic acid (CA) has potential anti-cancer properties, but its effectiveness can be improved by combining it with Folic acid (FA). This research aimed to evaluate the impact of CA and CA-FA conjugate on breast cancer cell lines (MCF-7, MDA-MB-231, and MCA10).
Materials And Methods: The viability of the cell lines was measured using the MTT assay, and the IC₅₀ was determined to compare the cytotoxicity of CA and CA-FA.

Background: Shenghui Decoction (SHD) is a frequently utilized traditional Chinese medicine formula in clinical settings for addressing cognitive impairment in elderly individuals. Nevertheless, the precise mechanism by which SHD exerts its effects on the most prevalent form of dementia, Alzheimer's disease (AD), remains to be elucidated.
Methods: Temperature-induced transgenic C.
