Explain with specific examples how oncogenic receptors would promote cellular proliferation in the absence of external growth factors

Briefly describe how inflammation can contribute to carcinogenesis and disease progression through heterotypic signaling.

describe how the cellular response to EGF results in tissue repair (epidermal growth factor)

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.
