Age-related obesity significantly increases the risk of chronic diseases such as type 2 diabetes, cardiovascular diseases, hypertension, and certain cancers. The insulin-leptin axis is crucial in understanding metabolic disturbances associated with age-related obesity. Rho GTPase Cdc42 a member family GTPases that participates many cellular processes including, but not limited to, regulation actin cytoskeleton, vesicle trafficking, cell polarity, morphology, proliferation, motility, migration. functions an integral part regulating insulin secretion aging. Some novel roles for have also been recently identified maintaining glucose metabolism, where involved controlling blood levels metabolically active tissues, including skeletal muscle, adipose tissue, pancreas, etc., which puts this protein line other critical regulators metabolism. Importantly, plays vital role leptin signaling pathways, are elements development if misregulated. Additionally, change activity may affect senescence, thus contributing to disorders This review explores complex relationships among age-associated obesity, axis, pathway. article sheds light on vast molecular web supports dysregulation aging people. In addition, it discusses potential therapeutic implications pathway mitigate since some new data suggest inhibition using antidiabetic drugs or antioxidants promote weight loss overweight obese patients.

Autonomic innervation is important to regulate homeostasis in every organ of the body. The sympathetic nervous system controls several organs associated with metabolism and reproduction, including adipose tissue, liver, ovaries. controlled within central by neurons located hypothalamus, which turn are regulated hormones like leptin. Leptin action hypothalamus leads increased activity tissue. In this short report, we propose that leptin brain also other liver ovary. We performed two experiments: an intracerebroventricular (ICV) injection measured norepinephrine levels organs, used a validated model overnutrition obesity evaluate whether increase coexists high Norepinephrine was ELISA tissue HPLC-EC tissues. ELISA. found ICV increases Also, diet-induced while inducing Finally, since hyperactivity observed both non-alcoholic fatty disease polycystic ovary syndrome, think induced hyperleptinemia could be involved pathogenesis diseases.

Preterm birth and its related complications have become more common as neonatal medicine advances. The concept of "developmental origins health disease" has raised awareness adverse perinatal events in the development diseases later life. To explore this concept, we propose that encephalopathy prematurity (EoP) a potential pro-inflammatory early life event becomes novel risk factor for metabolic children/adolescents adulthood. Here, review epidemiological evidence links preterm to discuss possible synergic roles neuroinflammation from EoP diseases. In addition, theoretical underlying mechanisms regarding developmental programming energy control system HPA axis.

Thyrotropin-releasing hormone (TRH; pGlu-His-Pro-NH2) is an intercellular signal produced mainly by neurons. Among the multiple pharmacological effects of TRH, that on food intake not well understood. We review studies demonstrating peripheral injection TRH generally produces a transient anorexic effect, discuss pathways might initiate this and explain its short half-life. In addition, central administration can produce or orexigenic effects, depending site injection, are likely due to interaction with receptor 1. Anorexic most notable when injected into hypothalamus nucleus accumbens, while effect has only been detected brain stem. Functional evidence points neurons prime candidate vectors for action intake. These include caudal raphe nuclei projecting dorsal motor vagus, possibly from tuberal lateral tuberomammillary nuclei. For other neurons, anatomical physiological context impact in each synaptic domain still poorly The manipulation expression well-defined neuron types will facilitate discovery role control scene.

The adaptation to changing environmental cues represents a key prerequisite for the survival of an organism. Mammals, including humans, have evolved intricate endocrine signals convey information about nutritional status individual organs, cells, and eventually cell nucleus, trigger appropriate molecular-metabolic responses. To this end, mounting proper fasting response is determined by not only intra-organ adaptations but also inter-tissue crosstalk mechanisms that orchestrate whole-body energy homeostasis under nutrient-deprived conditions. Here, we shortly summarize recent advances in our current understanding processes driving adaptive with focus on between adipose tissue liver ketogenesis.
