- Some cancer cells release their own grown hormone rather than relying on growth hor- mones from elsewhere in the host organism. Which of the following describes the type of cell communication used by these cancer cells to promote their continued division? A juxtacrine signaling B с D endocrine signaling paracrine signaling autocrine signalingExplain, why many cancer cells maintain high concentrations of insulin-like growth factors (IGFs) in the microenvironment that surrounds them?Estrogen works by binding to the ER. It includes two types ER alpha and ER beta and the two receptors are highly homologous. How might this be relevant in cancer?
- A family is identified in which some individuals are heterozygous for an inactivating mutation of the calcium-sensing receptor, CaSR. These individuals are asymptomatic, but compared to their unaffected relatives, which of the following will be decreased? Group of answer choices Urinary calcium Plasma calcium Bone resorption Exocytotic activity in chief cells of the parathyroid glandsExplain the relationship between the variable number of tandem repeats in the insulin promoter (Class I versus Class III VNTR) and genetic susceptibility to autoimmune diabetes.Thyroid peroxidase iodinates tyrosine residues within the thyroglobulin protein, and this enzymatic reaction occurs in the cytoplasm of follicular cells of the thyroid gland. True False. Although the thyroid gland releases far more thyroxine (T4) that triiodothyronine (T3), it is T3 that is the active hormone that regulates gene expression in target cells. True False In Gravesâ disease, circulating levels of both thyrotropin releasing hormone (TRH) and TSH are very low compared to a normal person. True False I do not need explanation. I need just the answer.
- Improper cell signaling can lead to cancer. True FalseExplain with specific examples how oncogenic receptors would promote cellular proliferation in the absence of external growth factorsHow would a mutation in ras that leads to formation of a Ras proteinwith no GTPase activity affect a cell’s response to insulin?
