Insulin-like growth factor-1 short-period therapy stimulates bone marrow cells in obese swiss mice.

Cell Tissue Res 2021 May 11. Epub 2021 May 11.

Laboratory of Stem Cell Research, Department of Histology and Embryology, Institute of Biology, University of the State of Rio de Janeiro, Rio de Janeiro, Brazil.

Bone marrow cells (BMCs) from obese Swiss mice fed with Western diet show mitochondrial dysfunction. Obesity interferes with BMCs disrupting energetic metabolism, stimulating apoptosis, and reducing cell proliferation since adipose tissue releases inflammatory adipokines into the medullar microenvironment. These changes lead to reduction of BMC differentiation capacity and hematopoiesis impairment, a process responsible for blood cell continuous production through hematopoietic stem cells (HSCs).

Deletion of in Preosteoblasts Reveals a Role for the Mammalian Target of Rapamycin Complex 1 (mTORC1) Complex in Dietary-Induced Changes to Bone Mass and Glucose Homeostasis in Female Mice.

JBMR Plus 2021 May 24;5(5):e10486. Epub 2021 Mar 24.

Adelaide Medical School, Faculty of Health and Medical Science University of Adelaide Adelaide South Australia Australia.

The mammalian target of rapamycin complex 1 (mTORC1) complex is the major nutrient sensor in mammalian cells that responds to amino acids, energy levels, growth factors, and hormones, such as insulin, to control anabolic and catabolic processes. We have recently shown that suppression of the mTORC1 complex in bone-forming osteoblasts (OBs) improved glucose handling in male mice fed a normal or obesogenic diet. Mechanistically, this occurs, at least in part, by increasing OB insulin sensitivity leading to upregulation of glucose uptake and glycolysis. Read More

Institute of Russian, Eastern European and Central Asian Studies, Chinese Academy of Social Sciences, 10000 Beijing, China.

Financial activities are the government's material means of leveraging financial resources, maintaining the exercise of political power and achieving administrative goals through financial revenues and expenditures. Successive administrations have been learning lessons from their predecessors, exploring the government's financial goals in response to Russia's severe economic and social problems and constantly adjusting themselves according to the changing situation. These goals include privatization and property right reform (expansion of the financial base), transfer payment and redistribution (consolidation of the public base of the regime), economic regulation (stimulation of economic growth, exchange rate stability, reduction of inflation, and tax neutrality), and the guarantee of financial security (budget balance and expansion of reserves), which have gradually led to a set of relatively stable financial rules in the years.
