Ghrelin capacity for food but also dramatically lowers ghrelin levels compared to both lean controls and those that lost weight through dieting alone. However, studies are conflicting as to whether or not ghrelin levels return to nearly normal with gastric bypass patients in the long term after weight loss has stabilized. Bariatric surgeries involving vertical-sleeve gastrectomy reduce plasma ghrelin levels by about 60% in the long term. Ghrelin plasma concentration increases with age and this may contribute to the tendency for weight gain as people age. Ghrelin Ghrelin (pronounced ), the "hunger hormone", also known as lenomorelin (INN), is a peptide
Thyroid hormone receptor beta a cause of generalized thyroid hormone resistance (GTHR), a syndrome characterized by goiter and high levels of circulating thyroid hormone (T-T), with normal or slightly elevated thyroid stimulating hormone (TSH). Several transcript variants have been observed for this gene, but the full-length nature of only one has been observed so far. Thyroid hormone receptor beta has been shown to interact with: Thyroid hormone receptor beta Thyroid hormone receptor beta (TR-beta) also known as nuclear receptor subfamily 1, group A, member 2 (NR1A2), is a nuclear receptor protein that in humans is encoded by the "THRB" gene. The protein encoded by
