OBJECTIVE Adipocyte insulin resistance (IR) is a key feature early in the pathogenesis of type 2 diabetes mellitus (T2DM), and although scarce, data in the literature suggest a direct role for iron and iron metabolism-related factors in adipose tissue function and metabolism. Serum ferritin and transferrin were shown to be associated with muscle insulin resistance (IR) and T2DM, but little is k...
BACKGROUND The early occurrence regional nodal and distant metastases cholangiocarcinoma (CCA) is one of the major reasons for its poor prognosis. However, the related mechanisms are largely elusive. Recently, increasing evidences indicate that adipocytes might be involved in the proliferation, homing, migration and invasion of several malignancies. In the present study, we attempt to determine...
BACKGROUND It is recognized that the ability of adipose tissue to expand in response to energy excess, i.e. adipocyte maturation, is important in determining systemic abnormalities in glucose and lipid metabolism. Ectonucleotide pyrophosphatase phosphodiesterase 1 (ENPP1, also known as PC-1) has been recently reported to be involved in the pathogenesis of insulin resistance and related diseases...
Much knowledge of adipocyte biology has been learned from cell culture models, most notably 3T3-L1 cells. The 3T3-L1 model has several limitations, including the requirement of 2 weeks to generate adipocytes and the waning of adipogenic potential in culture. We have investigated the capacity of OP9 cells, a line of bone marrow-derived mouse stromal cells, to recapitulate adipogenesis. When OP9 ...
Adult rats of various strains became obese when they were fed a highly palatable diet for several months. Analysis of their adipose tissue morphology revealed increases in both adipocyte size and number in most depots. Reintroduction of an ordinary chow diet to such animals precipitated a period of weight loss during which only mean adipocyte size returned to normal. Adipocyte number remained a...
There are many known adipokines differentially secreted from the different adipose depots; however, their paracrine and autocrine effects on de novo adipocyte formation are not fully understood. By developing a coculture method of preadipocytes with primary subcutaneous and visceral adipocytes or tissue explants, we could show that the total secretome inhibited preadipocyte differentiation. Usi...
Adipocyte differentiation is regulated by intracellular reactive oxygen species (ROS) generation and mitochondrial fission and fusion processes. However, the correlation between intracellular ROS generation and mitochondrial remodeling during adipocyte differentiation is still unknown. Here, we investigated the effect on adipocyte differentiation of 3T3-L1 cells of intracellular ROS inhibition ...
Adipocytes isolated from apolipoprotein E (apoE)-knockout (EKO) mice display alterations in triglyceride (TG) metabolism and gene expression. The present studies were undertaken to evaluate the impact of endogenously produced adipocyte apoE on these adipocyte parameters in vivo, independent of the profoundly disturbed metabolic milieu of EKO mice. Adipose tissue from wild-type (WT) or EKO mice ...
Precursor cells to adipocytes were purified from the epididymal fat pads of small rats and studied in primary culture. A culture system in which substrate and cofactors were not rate-limiting for complete adipocyte conversion was used by utilizing an agarose feeding-layer. Detachment of cells from the culture dish was prevented by addition of a viscous layer of culture medium, containing methyl...
Abstract The specific niche adaptations that facilitate primary disease and Acute Lymphoblastic Leukaemia (ALL) survival after induction chemotherapy remain unclear. Here, we show Bone Marrow (BM) adipocytes dynamically evolve during ALL pathogenesis therapy, transitioning from cellular depletion in the leukaemia to a fully reconstituted state upon remission induction. Functionally, adipocyte n...
