conclusions the obtained results indicate that rsm is an effective method for the optimization of culture conditions for hes gene expression in e. coli. results a maximum rhes mrna level of 376.16% was obtained under the following conditions: 0.6 mm iptg, 7 hours post-induction time, and 0.9 cell density before induction. the level of rhes mrna was significantly correlated with post-induction t...

gliobalstoma multiforme (gbm) or grade 4 astrocytoma is the most malignant form of primary brain tumor. treatment of glioblastoma is difficult despite of surgery, radiotherapy and chemotherapy. patients with glioblastoma survive for less than 12 months. considering to biology function of glioblastoma, researchers have recently offered new therapeutic approaches such as cannabinoid therapy for g...

Background: Angiogenesis initiated by cancerous cells is the process by which new blood vessels are formed to enhance oxygenation and growth of tumor. Objective: In this paper, we present a new multiscale mathematical model for the formation of a vascular network in tumor angiogenesis process. Methods: Our model couples an improved sprout spacing model as a stochastic mathematical model of spro...

Angiogenesis is regulated by the local balance between angiogenesis stimulators and inhibitors. A number of endogenous angiogenesis inhibitors have been found in the body. The origin of these inhibitors is mostly extrinsic to the vasculature. Recently however, endothelial cells themselves have been found to produce angiogenesis inhibitors including delta-like 4 and vasohibin 1. These intrinsic ...

The expression of the placental growth factor (PGF) in cancer cells and tumor microenvironment can contribute to induction angiogenesis, supporting cell metabolism by ensuring an adequate blood supply. Angiogenesis is a key component as it facilitates delivery nutrients oxygen rapidly growing cells. PGF recognized novel target for anti-cancer treatment due its ability overcome resistance existi...
