Phosphorylation of signal transduction molecules is a major activating event that leads to dramatic changes in tumor growth. Some TKs, such as epidermal growth factor receptor (EGFR)-TK, can autophosphorylate when activated, as well as phosphorylating other signaling molecules [2].
Risk indexes Definition: Categories of risk used to calculate fundamental beta, including (1) market variability, (2) earnings variability, (3) low valuation, (4) immaturity and smallness, (5) growth orientation, and (6) financial risk.
A risk is not an uncertainty (where neither the probability nor the mode of occurrence is known), a peril (cause of loss), or a hazard (something that makes the occurrence of a peril more likely or more severe). 5. Securities trading: The probability of a loss or drop in value. Trading risk is divided into two general categories: (1) Systemic risk affects all securities in the same class and is linked to the overall capital-market system and therefore cannot be eliminated by diversification. Also called market risk. (2) Nonsystematic risk is any risk that isn't market-related or is not systemic.
