Cystic fibrosis (CF) is an inherited autosomal recessive disease that is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The present study aimed to investigate the genetic modification of CF with ΔF508 mutation of the CFTR gene using CRISPR in peripheral blood mononuclear cells (PBMCs). Two single guide RNAs were designed to target sequences in the CFTR gene. The transfection efficiency of PBMC cells was examined through evaluation of green fluorescent protein (GFP) expression using fluorescent microscopy. Moreover, a sgRNA-Cas9 plasmid was tested to target the CFTR gene. The ΔF508 gene modification was evaluated and confirmed by PCR and Sanger sequencing methods. Our results indicate the feasibility of site-specific gene targeting with the CRISPR/Cas9 system. 33% of the samples were corrected using CRISPR in mutant locus and confirmed by sequence blast at NCBI databases and primers outside the arm locus. CRISPR/Cas9 approach represents an efficient tool to repair the ΔF508 mutation of the CFTR gene in PBMC Cells. Therefore, the CRISPR system can be highly efficient and specific and provides a powerful approach for genetic engineering of cells and model animals. Generally, the proposed method opens new insights into the treatment of human diseases.

Chemotherapeutic agents used during treatment induce cytotoxic effects also on normal cells in the tissues. Anti-oxidants used in combination with chemotherapeutic agents have been shown to reduce toxicity on normal cells to a minimum, and some anti-oxidant substances have chemotherapeutic effects. Cisplatin (CDDP) is a platinum class drug that is used clinically in the treatment of many cancers. Resveratrol (RSV) is a natural polyphenol with potent anti-oxidant and anticancer properties. In this study, we aimed to investigate apoptotic effects of using cisplatin and RSV alone or in combined treatment of MDA-MB-231 cells. The cytotoxic effects of the drugs on MDA-MB-231 cells were determined by MTT method. Subsequently, the change in CDDP-induced apoptotic effect after RSV addition was examined using the AnnexinV FITC labeling, and TUNEL staining method. Activation of caspase-9, -3 in MDA-MB-231 cells was measured by flow cytometer. The mitochondrial membrane potential (MMP), the major factor on the intrinsic pathway, was measured using flowcytometry. The combined dose (23 μM CDDP + 72 μM RSV) produced more cytotoxicity than the agents used alone, leading to early apoptosis (8.2%), 31% depolarization, and 23% DNA fragmentation. Caspase-9 was found to be 30.5% in this combined group and caspase-3 was 26.3%. RSV, an effective anti-oxidant, and CDDP as an effective drug in cancer treatment, were found to increase apoptosis when given in the MDA-MB-231 cell. RSV, an effective anti-oxidant, and CDDP as an effective drug in cancer treatment, were found to increase apoptosis when given in the MDA-MB-231 cell. This research was designed to demonstrate the impact of voluntary exercise on sperm parameters including sperm count, morphology, motility, viability, testicular apoptosis, oxidative stress, and the mir-34a/SIRT1/p53 pathway in type 2 diabetic rats. 32 Wistar male rats were separated into four groups control (C), voluntary exercise (VE), diabetic (D), and diabetic rats that performed voluntary exercise (VED). To induce diabetes, animals were injected with streptozotocin (35 mg/kg) after receiving a high-fat diet.
