Objective: The mitochondria isolation method is used to investigate mitochondrial processes. RT-qPCR measurement of gene transcription levels frequently in these studies. In this method, it important that the housekeeping genes normalisation results are stable. study aimed determine which two more stable isolated mitochondria. Material and Method: Mitochondria were from FHC cells. Membrane integrity functionality measured by mitotracker JC-1 stainings ROS ratio flow cytometry. Housekeeping...

Neuroblastoma, an embryonic tumor of the sympathetic nervous system, is deadliest type cancer, accounting for 6-9% all childhood cancers. The omega (ω)-6 [linoleic acid (LA)]: ω-3 [eicosapentaenoic (EPA)]=13/1 ratio associated with presence chronic disease, and it has been reported that reducing this to 7/1 protects against cancer cardiovascular diseases. This study aimed investigate anticancer effects different ratios ω-6 fatty acids in human neuroblastoma cells (SHSY-5Y). SHSY-5Y were...

Colorectal cancer (CRC) remains a crucial health problem due to the toxicity of 5-Fluorouracil (5-FU) as first-line chemotherapy agent for treating CRC. The anticancer effects boron and its compounds have been shown in various cell lines. This study aimed examine cytotoxic apoptotic borax (sodium tetraborate) alone or along with 5-FU on human CRC cells, DLD-1.Cytotoxicity apoptosis were determined by 3-(4,5-dimethylthiazolyl-2)-2,5-diphenyltetrazolium bromide (MTT) assay,...

Abstract Radiofrequency (RF) fields have been classified as probable human carcinogens and non-thermal RF-radiation (RFR) can cause an increase in oxidative stress inflammation tissues. Vitamin D has researched for many years its anti-cancer suppressive effects on cancer cell growth. In this study, we aimed to examine the of exposure RF signals viability, free radical formation, related inflammation, restorative effect vitamin against this. For purpose, MCF-7 MDA-MB-231 cells were exposed...

Background: More than 768 million people have been affected by COVID-19. Identifying lymphocyte subsets and cytokine level abnormalities in COVID-19 patients is essential to gain new insights data on immunity mechanisms against viral infections. Objectives: We used flow cytometry determine the relationship between disease severity, distribution, alterations patients. Methods: Totally 94 (32 mild, 31 moderate, severe) 27 healthy individuals were included cross-sectional study. The...
