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.
Parts | Limit Switches. Limit switches are safety devices that can cut power to certain functions of your hoist. If you exceed a certain weight, number of rotations, or lift a load too high, the limit switch will shut off the cranes electricity to the hydraulics or other system that raises the load.
