<prompt> In diseases of growth hormone cell death occurs by-AgingApoptosisNecrosisAll of the above  <response>: Ans. is b i.e., Apoptosis o GH and IGF-1 somatomedin inhibit cell death by apoptosiso Thus, GH deficiency will cause accelerated apoptosis.GH indirectly mediates growth and protein synthesis by triggering the liver and other tissues to produce a group of proteins called insulin-like growth factors IGFs. These proteins enahnce cellular proliferation and inhibit apoptosis or programmed cell death -- Science in medicine.
