How does the body weight of myostatin knockout mice compare to wild-type controls?5 answersMyostatin knockout (Mstn-KO) mice exhibit differences in body weight compared to wild-type controls. Mstn-KO mice generally show larger skeletal muscles and altered organ weights, indicating a significant impact on body composition. In contrast, studies on GH gene manipulation models show that GH receptor knockout (GHR-/-) mice with reduced GH/IGF-1 action have increased muscle strength and reduced body weight, while bovine GH transgenic (bGH) mice with excess GH/IGF-1 action display higher body weight and lean mass. Additionally, pharmacologic blockade of the myostatin pathway results in muscle hypertrophy without significant changes in body weight, highlighting the complex relationship between myostatin and body mass regulation. Therefore, myostatin knockout can lead to variations in body weight compared to wild-type controls, influenced by factors like muscle mass, GH/IGF-1 levels, and metabolic changes.
How does myostatin contribute to the development and progression of diabetic nephropathy in patients?5 answersMyostatin contributes to the development and progression of diabetic nephropathy (DN) by activating the nuclear factor-κB pathway in macrophages. Increased serum levels of mannose-binding lectin (MBL), a crucial mediator in DN, promote inflammatory responses in macrophages, leading to enhanced IL-1β production and M1 polarization. MBL directly induces inflammatory and fibrotic markers in renal cells during co-culture. In db/db mice, downregulation of MBL ameliorates blood glucose, triglyceride, urine protein, glomerular and tubular injuries, as well as renal inflammation and fibrosis. Overexpression of MBL promotes macrophage infiltration in the kidney. These findings suggest that MBL, through its activation of the nuclear factor-κB pathway in macrophages, plays a crucial role in the progression of DN.
What is myostatin?5 answersMyostatin is a protein that belongs to the transforming growth factor β (TGF-β) superfamily. It was initially discovered as a negative regulator of skeletal muscle growth. Myostatin is produced by skeletal myofibers and circulates in the blood, acting back on myofibers to limit muscle growth. It functions as a master regulator of skeletal muscle mass and plays a role in controlling tissue size. Recent studies have also shown that myostatin has potential activities outside of the musculoskeletal system, including in various reproductive organs such as the ovary, placenta, and uterus. In addition, myostatin has been associated with metabolic syndrome, a complex metabolic disorder characterized by obesity, hyperglycemia, hypertension, and hyperlipidemia. Overall, myostatin is a protein that regulates muscle growth and has implications in various physiological and pathological conditions, including reproductive disorders and metabolic syndrome.
