Cytotoxic Activity Of Salvia Officinalis Extract Mediated By The Inhibition Of Jak2 In Breast Cancer, Salma Alawadi Dawood

Theses and Dissertations

Background: Breast cancer is the most common type of invasive cancer in women in their forties and fifties. Recent evidence suggests that JAK2/STAT3 signaling is constitutively active in breast cancer. Previous studies suggest that plant extracts, including Salvia Officinalis, have strong cytotoxic effects on breast cancer cells. The differential expression of miRNAs is also strongly linked to cancer development.

Aim: In the current study, we hypothesize that S. Officinalis extract suppresses JAK2 expression and has strong anticancer potential in MCF7 breast cancer cell lines.

Methods: GC-MS analysis showed the presence of flavonoids in dried leaf of …

Atomistic Assessment Of Drug-Phospholipid Interactions Consequent To Cancer Treatment: A Study Of Anthracycline Cardiotoxicity, Yara Elsayed Ahmed

Theses and Dissertations

Despite being one of the most effective chemotherapeutic agents developed to date, Anthracyclines are notorious for their cardiotoxicity. Their clinical use is frequently limited both in dosage and in prescription due to the severe cardiac damage they cause. The mechanism of anthracycline-induced cardiotoxicity is not yet fully understood. However, it is hypothesized that interactions with the myocardial membrane play an important role in imparting cardiotoxicity. In this study, we use molecular dynamics simulations and density functional theory calculations to study the anthracycline drug molecules and the interactions that they have with the myocardial membrane. We construct a myocardial membrane model …

Optimization Of In-Vitro Tissue Culture And Transformation System For Sweet Sorghum Cultivars Using Immature Inflorescence, Logayn Abushal

Theses and Dissertations

Background: Sweet sorghum is a multi-purpose crop that can be used for human food, animal feed, and bio-fuel production. This crop is drought-tolerant and can therefore be grown in arid and semi-arid regions especially in marginal areas in Egypt. Nevertheless, production of Sweet sorghum cannot coup with the increasing demand in consumption as a food, and fuel due to a lag in scientific research regarding its genetic improvement. Therefore, genetic improvement of Sweet sorghum is innately required so that new traits of economic importance could be introduced; however, this can only be achieved through the establishment of a robust in-vitro …
