Morphological and Morphometric Analysis, Apoptosis and Oxidative Stress Study in Hep 2 Cells Treated by Resveratrol or Quercetine

Int. j. morphol; 42 (4), 2024
SUMMARY: Resveratrol (RES) and quercetine (QRC), is a promising agent relevant for both cancer chemoprevention and treatment via several signaling pathways, involved in their anticancer activity related to its chemotherapeutic potential, associated with the induction of ROS generation in cancer cells, le...

Protective effect of trans-nerolidol on vascular endothelial cell injury induced by lipopolysaccharides

This article aimed to discuss the protection of trans - nerolidol on vascular endothelial cells (ECs) injured by lipopolysac charides. ECs were divided into four groups: normal, model, low and high dose trans - nerolidol treatment groups. The cell survival rate and th...

Influences of Glabridin Treatment on Motor Function Recovery after Spinal Cord Injury

Int. j. morphol; 42 (3), 2024
SUMMARY: Spinal cord injury (SCI) usually arises from compression due to traffic accidents and falls, resulting in varying degrees of movement, sensory loss, and possible paralysis. Glabridin (Gla) is a natural compound derived from licorice. It significantly affects drug development and medicine because...

Evaluation of the immunomodulatory effect of Bougainvillea xbuttiana (Var. Orange) on the cytokine production induced by Botrhops jararaca venom in macrophages

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...

Cytotoxic effects of bioceramic materials on stem cells from human exfoliated deciduous teeth (SHED)

Braz. dent. sci; 27 (2), 2024
Objective: This study aimed to evaluate stem cell from human deciduous teeth (SHED) viability after exposure to different bioceramic materials. Material and Methods: Discs were constructed to obtain the material extracts according to the following groups: G1 - Bio-C Repair, G2 - MTA Repair HP, G3 - Thera...

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...

Acidic Environment Induces Pyroptosis of NLRP3 Inflammatory Vesicle-Mediated Nucleus Pulposus Cells Through Up-Regulation of POSTN Expression

Int. j. morphol; 41 (6), 2023
SUMMARY: Intervertebral disc degeneration (IVDD) is induced by nucleus pulposus (NP) dysfunction as a result of massive loss of NP cells. It has been reported that the acidic microenvironment of the intervertebral disc (IVD) can induce NP cell pyroptosis, and that up-regulation of periostin (POSTN) expre...

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...
