To study the effect of 50% ethanol extract of Bougainvillea xbuttiana on the enzymatic activity, cell via bility and cytokine production provoked by the venom of Bothrops jararaca in macro - phages. Three assays were used to study the effects of B. xbuttiana extract on the dama...

Modulación por Passiflora edulis de triglicéridos y colesterol intracelulares en líneas celulares de cáncer colorrectal SW480 y sus derivadas metastásicas (SW620)

Cancer cells modify lipid metabolism to proliferate, Passiflora edulis ( P. edulis ) fruit juice (ZuFru) has antitumor activity, but whether a mechanism is through modulation of cell lipids is unknown. T o establish if ZuFru modifies cholesterol and triglycerides in SW480 and SW620...

Protective Autophagy in 5-Fluorouracil-Resistant Colorectal Cancer Cells and ERK-RSK-ABCG2 Linkage

Int. j. morphol; 41 (6), 2023
SUMMARY: To evaluate the anti-cancer effects of yeast extract on resistant cells, autophagy and necroptosis were investigated in 5-fluorouracil (5-FU)-resistant colorectal cancer cells. Further underlying characteristics on drug resistance were evaluated, focused on ERK-RSK-ABCG2 linkage. SNU-C5 and 5-FU...

Ethyl acetate extract of Clausena execavata promotes growth inhibition of Burkitt’s lymphoma cell line via apoptotic activities

Clausena excavata is a famous folklore medicinal plant in Asian region that is being used for the treatment of different disorders. This study investigated the cytotoxic effects of leaf extracts via MTT assay, as well as the in vitro apoptotic activities of the ethyl acetate C. excavata leaf extract (E...

Identification of antarctic soil bacteria exhibiting antiproliferative activity against a colon cancer cell line

Int. j. morphol; 41 (1), 2023
SUMMARY: Cancer is the second leading cause of death in the world and colorectal cancer is the only cancer that has shown a sustained increase in mortality in the last decade. In the search for new chemotherapeutic agents against cancer, extremophilic microorganisms have shown to be a potential source to...

Mitochondrial energy metabolism in baby hamster kidney (BHK-21/C13) cells treated with karnozin extra®

Int. j. morphol; 40 (1), 2022
SUMMARY: Carnosine is known as a natural dipeptide, which inhibits the proliferation of tumor cells throughout its action on mitochondrial respiration and cell glycolysis. However, not much is known about its effects on the metabolism of healthy cells. We explored the effects of Karnozin EXTRA® capsule ...
