1 HER-2/neu encodes for a cell surface receptor that can stimulate cell division. 2  The HER-2/neu gene is amplified in up to 30% of human breast cancers.3  RAS. 4  The Ras gene products are involved in kinase signaling pathways that ultimately control transcription of genes, regulating cell growth and differentiation. few important tumor-suppressor genes: 1  p53: a transcription factor that regulates cell division and cell death. 2  Rb: alters the activity of transcription factors and therefore controls cell division. 3  APC: controls the availability of a transcription factor.
Cable Limiters. Cable Limiters. Cable limiters are distinguished from fuses by their intended purpose of. providing only short circuit response: they are not designed to provide over-. load protection. Typically, cable limiters are selected based on conductor size. They are available in a wide range of types to accommodate the many.
Only the affected cable(s) are removed from. service by the cable limiters at each end opening, (assuming three or more cables. per phase, with cable limiters on each end). 2. The isolation of a faulted cable permits the convenient scheduling of repair service.
