Moringa grows in the tropical and subtropical regions of the world. The genus belongs to family Moringaceae. It is found to possess various medicinal uses including hypoglycemic, analgesic, anti-inflammatory, hypolipidemic, and antioxidant activities. In this study, we investigated the antimicrobial and the anticancer activity of the as well as leaves extracts grown locally in Egypt. Results indicated that most of the extracts were found to possess high antimicrobial activity against gram-positive bacteria, gram-negative bacteria, and fungus. The survival rate of cancer cells was decreased in both hepatocellular carcinoma (HepG2) and breast carcinoma (MCF-7) cell lines when treated with leaves extracts. In addition, the cell cycle progression, apoptosis, and cancer-related genes confirmed its anticancer effect. The toxicity of each extract was also tested using the normal melanocytes cell line HFB4. The toxicity was low in both and leaves extracts. Furthermore, GC/MS analysis fractionized the phytochemicals content for each potential extract. In conclusion, results suggested that the and leaves extracts possess antimicrobial and anticancer properties which could be attributed to the bioactive phytochemical compounds present inside the extracts from this plant. These findings can be used to develop new drugs, especially for liver cancer chemotherapy.

Date Palm Sex Differentiation Based on Fluorescence In Situ Hybridization (FISH).

Methods Mol Biol 2017 ;1638:245-256

National Gene Bank, Agriculture Research Center, Giza, Egypt.

In situ hybridization (ISH) is used to visualize defined DNA sequences in cellular preparations by hybridization of complementary probe sequences. Recently, the fluorescence in situ hybridization (FISH) technique has become a powerful and useful tool for the direct detection of specific DNA fragments in the genome. Ribosomal DNA genes (45S and 5S rDNA) are commonly used as markers for the physical mapping of plant chromosomes to analyze genomic organization. Here we describe cytological-based markers to differentiate date palm gender through localization of 45S and 5S rDNA markers on date palm chromosomes using FISH.
