Anti-Angiogenic Effect of Cantharellus cibarius Extracts, its Correlation with Lipoxygenase Inhibition, and Role of the Bioactives Therein

Angiogenesis is a complex physiological process that cannot be treated with single agent therapy. Several edible fungi have been known to encompass bioactive compounds, and are promising sources of multi-component drugs. One such widely consumed edible fungi is Cantharellus cibarius, which has been explored for its biological activities. The present study focused on assessing the anti-angiogenic activity of petroleum ether and ethanol extracts of C. cibarius using chick chorioallantoic membrane (CAM) assay. Both the extracts showed a dose-dependent response which was compared with the anti-angiogenic activity of the positive controls silibinin, and lenalidomide. The extracts were also studied for their lipoxygenase (LOX) inhibitory potential and compared to ascorbic acid as the positive control. The IC50 values of the petroleum ether extract, ethanol extract, and ascorbic acid for LOX inhibition assay were 135.4, 113.1, and 41.5 mg/mL, respectively. Although both the extracts showed similar responses in CAM assay, ethanol extract proved to be more potent in LOX inhibition assay. Finally, the extracts were investigated for their chemical composition using GC-MS. A correlation between LOX inhibition and anti-angiogenic potential was established at the molecular level. A meticulous literature search was carried out to correlate the biochemical composition of the extracts to their anti-angiogenic activity arabic 19 English 119

Thermodynamic study of BRAF V600 mutations in colorectal cancer patients

The detection of somatic mutations in tumours is essential for the understanding of cancer development and targeting therapy. The screening for BRAF V600E mutation is employed in clinical practice in Libya for its prognostic and potentially predictive role in patients with metastatic colorectal carcinoma (mCRC). Using of BRAF mutant DNA and wild type DNA targets, we found that the sensitivity of allelic discrimination-Real Time PCR was applicable. The Real Time PCR assay displayed increased analytical sensitivity in detecting the BRAF V600E mutation. The association of BRAF mutations with clinical and pathological features was assessed using Real Time PCR assay. Qiagen Real Time PCR Platform was utilised using a set of primers. forward 5-GAC.

Our study indicates that Real Time PCR-based assays is convenient to detect the BRAF V600E mutation in CRC and that BRAF mutations screening should not be restricted to selected patients on the basis of the clinicalpathological characteristics. arabic 9 English 63

A comparative evaluation of two DNA extraction protocols from whole blood sample

Every organism has deoxyribonucleic acid (DNA) within their cells. DNA is a complex molecule that contains all of the information needed to build and maintain living organisms. Extraction of deoxyribonucleic acid (DNA) is one of the most basic and critical steps affecting molecular-based techniques in the study of DNA that allow vast advances in genetic, molecular biology, biotechnology, forensic, and bioinformatics laboratories. Therefore, researchers have been used different modified and optimized protocols for efficient genomic DNA extraction from biological samples. Due to the high amount of genetic material in whole blood samples so it's one of the main sources used to obtain DNA and there are many different protocols available in this issue. In the present study, we optimized, evaluated by comparison to phenol-chloroform (traditional method) and silica column (QIAamp DNA Blood Mini Kit) DNA extraction procedures. The extracted DNA by these protocols was analyzed according to their time consuming, quality, quantity, cost and toxicity. Extracted DNA with current protocol was qualified using gel electrophoresis, Nanodrop spectrophotometric analysis. Our results showed that there are not significantly differences between these methods about DNA Purity (A260/A280) and DNA yield (ng DNA/μl). In addition, phenol/chloroform (traditional method) was the most toxic method; it takes more time but cheaper than other method; it yielded reasonably good quantities of good quality DNA and would be suitable for large-scale genotyping of blood samples. The silica column method (QIAamp DNA Blood Mini Kit) was the most expensive among the other method but the least extraction time was required and it was the safest method. arabic 11 English 69
