Several mutations of cardiac beta-myosin heavy chain (beta-MHC) gene were reported in patients with hypertrophic cardiomyopathy (HCM). Involvement of proto-oncogenes has been shown in the mechanism of experimental cardiac hypertrophy. This study sought to examine the effects of c-H-ras and c-myc expression in the steady-state myocardium on hypertrophic changes and to evaluate the possible inter...
The RET proto-oncogene encodes a receptor tyrosine kinase for transforming growth factor-beta-related neurotrophic factors, which include GDNF and neurturin. The expression of RET proto-oncogene was detected in several tissues, such as spleen, thymus, lymph nodes, salivary gland, and spinal cord, and in several neural crest-derived cell lines. RET expression in the thyroid gland was reported to...
Alveolar macrophages from normal individuals and patients with interstitial lung diseases spontaneously expressed a 4.2-kilobase mRNA complementary to the c-sis gene, a proto-oncogene coding for one of the chains of platelet-derived growth factor (PDGF). Concomitantly, these cells released a mediator with the properties of PDGF, including: chemotactic factor for smooth muscle cells whose activi...
We previously demonstrated that b4 integrin subunit overexpression increases in vitro invasiveness of NIH3T3 cells that have been transformed by ErbB-2 oncogene. We used this model to identify domains within the large b4 cytoplasmic domain that are involved in the interaction of a6b4 with ErbB-2, invasion, and phosphatidylinositol 3-kinase (PI3K) activation. For this purpose, we expressed delet...
ErbB-2 (HER-2/neu) is a transforming oncogene expressed by a substantial fraction of breast cancers, and monoclonal antibody therapy directed toward this antigen is an established treatment modality. However, not all tumors respond, and with a monoclonal antibody directed to a single epitope, there is always the risk of tumor escape. Furthermore, passive antibody therapy requires continual trea...
The product of the c-myc proto-oncogene is an important positive regulator of cell growth and proliferation. Recently, c-Myc has also been demonstrated to be a potent inducer of apoptosis when expressed in the absence of serum or growth factors. To further examine Myc-induced apoptosis, we coexpressed the proto-oncogene bcl2, which has been shown to block apoptosis in other systems, with c-myc ...
