The Drosophila embryonic Central Nervous System (CNS) develops from the ventrolateral region of the embryo, the neuroectoderm. Neuroblasts arise from the neuroectoderm and acquire unique fates based on the positions in which they are formed. Previous work has identified six genes that pattern the dorsoventral axis of the neuroectoderm: Drosophila epidermal growth factor receptor (Egfr), ventral...
Although platelet-rich plasma (PRP) is the plasma fraction that contains higher levels of platelet-sequestered proteins such as growth factors and chemokines, it is also abundant in bioactive lipids whose role in wound healing has not been well characterized. This study provides a preliminary evaluation for the effect of the lipid component of PRP on selected genes related to wound healing. Spr...
introduction: growth, proliferation, survival, and differentiation are the prominent characteristics of cells, which are affected by cancer. epidermal growth factor receptor (egfr) plays a pivotal role in the effective control of these features. given the significance of egfr signaling pathway in non-small cell lung cancer (nsclc), egfr expression is influential on these cell characteristics. i...
Anomalies of the epidermal growth factor receptor (EGFR) gene, including amplification, rearrangement, and overexpression, have been reported in malignant human gliomas in vivo. In vitro glioma cell lines coexpress EGFR and at least one of its ligands, transforming growth factor alpha, suggesting the existence of an autocrine growth stimulatory loop. We have studied the tumor tissue from 62 hum...
Modulating the behaviors of reactive astrocytes is a potential therapeutic strategy for neurodegenerative diseases. We found that upregulation and activation of the epidermal growth factor receptor (EGFR) occur in astrocytes after different injuries in optic nerves in vivo. Activation of EGFR regulates genes and cellular processes representing most major markers of reactive astrocytes and genes...
UNLABELLED The EGFR-targeted antibodies cetuximab and panitumumab are used to treat metastatic colorectal cancers. Mutations in KRAS, NRAS, and BRAF and amplification of ERBB2 and MET drive primary (de novo) resistance to anti-EGFR treatment. Recently, the emergence of alterations in the same genes was detected in patients who responded to EGFR blockade and then relapsed. These results illumina...
Control of mesangial cell growth and matrix accumulation is critical for normal development of the glomerular tuft and progression of glomerular injury, but the genes that control mesangial cell growth are not well understood. We used high-density oligonucleotide microarrays to analyze gene expression in well-differentiated human mesangial cells treated with serum to stimulate proliferation. Pa...
Platinum-based chemotherapy remains the main treatment of advanced lung cancer. However, platinum resistance has become a major treatment obstacle. Novel therapies, particularly tyrosine kinase inhibitors of the epidermal growth factor receptor (EGFR-TKI) and agents that target vascular endothelial growth factor (VEGF), have improved the treatment. Both chemotherapy and targeted therapy have th...
گیرنده فاکتور رشد اپیدرمی (egfr) نشان داده شده است که نقش اساسی در رشد سلول توموری دارد و افزایش بیان آن در درصد قابل توجهی از تومورهای انسانی مشاهده شده است. تا به امروز روش های متعددی در درمان سرطان بر اساس هدف قرار دادن egfr گسترش یافته است. در زمینه واکسن سرطان یکی از استراتژی ها ایمنی درمانی فعال علیه گیرنده می باشد بدین منظور که افزایش فعالیت آن مهار گردد. از طرف دیگر از آنجاییکه ذرات فاژ...
UNLABELLED Persistent signaling by the oncogenic EGF receptor (EGFR) is a major source of cancer resistance to EGFR targeting. We established that inactivation of 2 sterol biosynthesis pathway genes, SC4MOL (sterol C4-methyl oxidase-like) and its partner, NSDHL (NADP-dependent steroid dehydrogenase-like), sensitized tumor cells to EGFR inhibitors. Bioinformatics modeling of interactions for the...
