Withania Alter BCL2/Bax signaling and trigger apoptosis of MCF-7 and MDA-MB231 breast cancer cells exposed to γ-radiation.

Treatment strategies encompass synchronization of more than one therapy with specific dependence on zeroing side effects of natural products that might represent a niche in the continuous struggle against cancer. Thus, this study aimed at assessing the role of WS (Ashwagandha) in forcing MCF7 or MDA-MB 231 irradiated breast cancer cells to outweigh the route of programmed cell death. We check to what extent SIRT1-BCL2/Bax signaling pathway was interrelated to form apoptotic cancer cells.

FA-HA-Amygdalin@FeO and/or γ-Rays Affecting SIRT1 Regulation of YAP/TAZ-p53 Signaling and Modulates Tumorigenicity of MDA-MB231 or MCF-7 Cancer Cells.

Background: Breast cancer (BC) has a complex and heterogeneous etiology, and the emergence of resistance to conventional chemo-and radiotherapy results in unsatisfactory outcomes during BC treatment. Targeted nanomedicines have tremendous therapeutic potential in BC treatment over their free drug counterparts.

Objective: Hence, this study aimed to evaluate the newly fabricated pH-sensitive multifunctional FAHA- Amygdalin@FeO nano-core-shell composite (AF nanocomposite) and/or γ-radiation for effective localized BC therapy.

Withania somnifera (Ashwagandha) root extract counteract acute and chronic impact of γ-radiation on liver and spleen of rats.

The exposure to ionizing radiation has become inescapably because of increased dependence on radiation to execute works in different fields and also its influences on biological systems. Thus, the current study aimed at examination of the radio-protective effect of the natural ashwagandha (Ag) against acute and chronic doses of γ-radiation on liver and spleen of rats. The impact of Ag was inspected in rats exposed to acute exposure of 8 Gy (single dose) or to chronic exposure of 8 Gy (2 Gy every other day for 4 times).

Ex vivo propagation in a novel 3D high-throughput co-culture system for multiple myeloma.

Purpose: Multiple myeloma (MM) remains an incurable hematologic malignancy which ultimately develops drug resistance and evades treatment. Despite substantial therapeutic advances over the past years, the clinical failure rate of preclinically promising anti-MM drugs remains substantial. More realistic in vitro models are thus required to better predict clinical efficacy of a preclinically active compound.

Genetic parameters controlling the inheritance of glaucousness and yield traits in bread wheat.

Wheat breeders frequently use generation mean analysis to obtain information on the type of gene action involved in inheriting a trait to choose the helpful breeding procedure for trait improvement. The present study was carried out to study the inter-allelic and intra-allelic gene action and inheritance of glaucousness, earliness and yield traits in a bread wheat cross between divergent parents in glaucousness and yield traits; namely Mut-2 (P1) and Sakha 93 (P2). The experimental material included six populations, i.

Mice were administered FX (10 mg kg-1 day-1, i.

Distribution of Extended-Spectrum β-Lactamase (ESBL)-Encoding Genes among Multidrug-Resistant Gram-Negative Pathogens Collected from Three Different Countries.

The incidence of Extended-spectrum β-lactamase (ESBL)-encoding genes ( and ) among Gram-negative multidrug-resistant pathogens collected from three different countries was investigated. Two hundred and ninety-two clinical isolates were collected from Egypt ( = 90), Saudi Arabia ( = 162), and Sudan ( = 40). Based on the antimicrobial sensitivity against 20 antimicrobial agents from 11 antibiotic classes, the most resistant strains were selected and identified using the Vitek2 system and 16S rRNA gene sequence analysis.

Evaluation of flour protein for different bread wheat genotypes.

Six different bread wheat genotypes; two Egyptian commercial varieties (control); Giza-168 and Gemmeiza-11, and four promising lines; L84 and L148, resulted via hybridization and M10 and M34 via radiation mutation program) were rheologically evaluated using extensograph and for protein, analysis using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The radiation mutant M10 and M34 had the highest maximum resistance which is a very good indicator of strong gluten. The amount of gluten content was higher in M10, L148, and M34 compared to the control samples Gz168 and Gm11.

Pro-apoptotic and anti-neoplastic impact of luteolin on solid Ehrlich carcinoma.bearing mice exposed to gamma radiation.

Background: Cancer remains a major health issue and the second foremost root of morbidity worldwide behind cardiovascular diseases. Apoptosis had linked to the eradication of possibly malignant cells, hyperplasia, and tumor progression.

Objective: The present study is an endeavor to evaluate the influence of luteolin, a modifier to apoptotic regulator on the tumor growth and the tumor cell sensitivity to ionizing radiation in Ehrlich solid tumor-bearing mice (E).

The Non-Coding RNA Landscape of Plasma Cell Dyscrasias.

Despite substantial advancements have been done in the understanding of the pathogenesis of plasma cell (PC) disorders, these malignancies remain hard-to-treat. The discovery and subsequent characterization of non-coding transcripts, which include several members with diverse length and mode of action, has unraveled novel mechanisms of gene expression regulation often malfunctioning in cancer. Increasing evidence indicates that such non-coding molecules also feature in the pathobiology of PC dyscrasias, where they are endowed with strong therapeutic and/or prognostic potential.

Comparative expression of caspases and annexin V in benign and malignant ovarian tumors.

Aim Of Study: Ovarian cancer (OC) leads to high mortality rate if diagnosed at late stage. The aim of the present study was to increase the survival rate by early disease diagnosis.

Antitumor and radiosensitizing synergistic effects of apigenin and cryptotanshinone against solid Ehrlich carcinoma in female mice.

Considerable attention has been paid to the introduction of novel naturally occurring plant-derived radiosensitizer compounds in order to augment the radiation efficacy and improve the treatment outcome of different tumors. This study was therefore undertaken to evaluate the antitumor, antiangiogeneic, and synergistic radiosensitizing effects of apigenin, a dietary flavonoid, and/or cryptotanshinone, a terpenoid isolated from the roots of Salvia miltiorrhiza, against the growth of solid Ehrlich carcinoma in female mice. Apigenin (50 mg/kg body weight) and/or cryptotanshinone (40 mg/kg body weight) was intraperitoneally (i.

Boswellic acid disables signal transduction of IL-6-STAT-3 in Ehrlich ascites tumor bearing irradiated mice.

Boswellic acid (BA) is known for its ability to trigger apoptosis as well as to inhibit angiogenesis in tumor tissue. In this study, we investigated the effect of BA on the IL-6-STAT-3 signalling pathway in irradiated mice bearing solid tumors of Ehrlich ascites carcinoma (EAC). For this, we administered BA (25 mg·(kg body mass)(-1)·day(-1), by intraperitoneal injection) to mice with EAC, and then exposed them to 4 Gy of gamma radiation.
