We recently demonstrated that the snake venom extracted from Walterinnesia aegyptia (WEV) either alone or combined with silica nanoparticles (WEV+NP) enhanced the proliferation of mice immune cells and simultaneously decreased the proliferation of human breast carcinoma cell line (MDA-MB-231). However, the molecular mechanism of how this venom induced growth arrest of breast cancer cells has no...

The aim of this study was to investigate the production H. scabra in an open pond culture system and evaluate nutritional value biological activities. H successfully grown with average size 15.3 cm weight 132.7 g after eight month period. cultured rich protein content (73.41%). extracts obtained from soxhletation method showed potential antioxidant anticancer activity against MDA-MB-231 breast ...

Employing particle swarm optimization (PSO) combined with first-principles calculations, we systemically studied high-pressure behaviors of hard CrB4. Our predictions reveal a distinct structural evolution under pressure for CrB4 despite having the same initial structure as FeB4. CrB4 is found to adopt a new P2/m structure above 196 GPa, another Pm structure at a pressure range of 261-294 GPa a...

An emphasis in early detection and more effective treatments has decreased the mortality rate of breast cancer. Despite this decrease, breast cancer continues to be the leading cause of death among women between 40 and 55 years of age and is the second overall cause of death among women. Hence, the aim of the present study was to assess the therapeutic efficacy of deguelin, a rotenoid isolated ...

A one-step synthesis of phloretin derivatives 2-11 from phloretin in good to excellent yields is reported. Their structures were characterized by 1H-NMR, 13C-NMR and MS, and the structures of 8 and 11 were determined by X-ray diffraction analysis. A mechanism for the formation of 9-11 is proposed. Compared with the anticancer drug docetaxel, phloretin, phloretin derivatives and phlorizin exhibi...

Parathyroid hormone-related peptide (PTHrP) is a major factor involved in tumor-induced osteolysis caused by breast cancers that have metastasized to bone. However, the molecular mechanisms that mediate PTHrP production by breast cancer cells are not entirely clear. We hypothesized that Gli2, a downstream transcriptional effector of the Hedgehog (Hh) signaling pathway, regulates PTHrP expressio...

Abstract Background Anoikis resistance plays a critical role in the tumor metastasis by allowing survival of cancer cells systemic circulation. We previously showed that long non-coding RNAs APOC1P1-3 (lncRNA APOC1P1-3) inhibit apoptosis breast cells. In this study, we explored its anoikis resistance. Methods induced two cell lines (MCF-7 and MDA-MB-231) under anchorage-independent culture cond...

BACKGROUND Vascular endothelial growth factor-D (VEGF-D) binds and activates vascular endothelial growth factor receptor-2 (VEGFR-2), which signals for angiogenesis, and VEGFR-3, which signals for lymphangiogenesis. Besides endothelial cells, VEGFR-2 has been detected on malignant cells, including human breast carcinoma cells. MATERIALS AND METHODS It was examined if ectopic expression of hum...
