Human immunodeficiency virus (HIV)-associated adipose redistribution syndrome (HARS) is a fat accumulation disorder characterized by increases in visceral adipose tissue. Patients with HARS may also present with excess truncal fat and accumulation of dorsocervical fat ("buffalo hump"). The pathophysiology of HARS appears multifactorial and is not fully understood at present. Key pathophysiologi...
M.E. Symonds (ed.), Adipose Tissue Biology, DOI 10.1007/978-1-4614-0965-6_1, © Springer Science+Business Media, LLC 2012 Abstract The current epidemic of obesity and overweight has caused a surge of interest in the study of adipose tissue formation. Much progress has been made in defi ning the transcriptional networks controlling the terminal differentiation of preadipocytes into mature adipocy...
Adipose tissue growth results from de novo adipocyte recruitment (hyperplasia) and increased size of preexisting adipocytes. Adipocyte hyperplasia accounts for the severalfold increase in adipose tissue mass that occurs throughout life, yet the mechanism of adipocyte hyperplasia is unknown. We studied the potential of macrophage colony-stimulating factor (MCSF) to mediate adipocyte hyperplasia ...
Background: Due to extensive use of cell cultures in biomedical investigations and researches, there has been a great need to identify, authenticize and accurate quality control of cells. Stem cells are characterized by their self-renewal and differentiation potential. Mesenchymal stem cells are found in various tissues. These cells are vastly used in cell therapy and regenerative medicine and ...
Studies dealing with the number or size of individual adipose cells in abnormal human bone marrow are lacking. To ascertain whether variations in fat tissue fraction depend on the size of individual adipocytes or their number or both, a stereologic study of 30 human bone marrow specimens (10 with aplasia, 10 with hyperplasia, and 10 with dysplasia) was performed. A total of 23,435 adipocyte pro...
We previously showed that human and murine 3T3-F442A preadipocytes produced and released matrix metalloproteinases (MMPs) 2 and 9 and that a treatment by MMP inhibitors resulted in the blockade of murine fat cell adipose conversion. In parallel, investigators reported that other protease inhibitors, the human immunodeficiency virus (HIV) protease inhibitors (PIs) involved in lipodystrophy in hu...
We have partially purified an 18-kDa cytoplasmic protein from 3T3-Ll cells, which dephosphorylates pNPP and the phosphorylated adipocyte lipid binding protein (ALBP), and have identified it by virtue of kinetic and immunological criteria as an acid phosphatase (EC 3.1.3.2). The cytoplasmic acid phosphatase was inactivated by phenylarsine oxide (PAO) (K,,,, = 10 pM), and the inactivation could b...
results the results showed that children with a higher weight z-score spend more time in sedentary activities and less time running or involved in active games. scd-1 activity index, arachidonic/linoleic index, and adipocyte volume were significantly higher in children with a weight z-score greater than 0. the preadipocyte number and the genetic expression of the studied genes did not differ be...
