Insights

Mammalian target of rapamycin (mTOR) signaling pathways are crucial for managing cardiovascular complications in diabetes. Understanding mTOR

Area of Science:

  • Cardiovascular Science
  • Metabolic Disease Research
  • Molecular Biology

Background:

  • Diabetes mellitus affects over 170 million people globally, with projections indicating a significant increase.
  • Diabetic complications, particularly cardiovascular issues, contribute to severe morbidity and mortality.
  • Oxidant stress is a key factor in the development of diabetic complications.

Purpose of the Study:

  • To explore the role of mammalian target of rapamycin (mTOR) signaling in cardiovascular complications of diabetes.
  • To investigate how mTOR pathways regulate cardiovascular and metabolic functions in diabetic individuals.
  • To identify novel therapeutic targets within the mTOR pathway for treating diabetic cardiovascular disease.

Main Methods:

  • Review of current literature on mTOR signaling in diabetes and cardiovascular disease.
  • Analysis of the regulatory functions of mTOR complexes (TORC1 and TORC2) in metabolic and cardiovascular systems.
  • Examination of the dual role of mTOR in insulin signaling and insulin resistance.

Main Results:

  • mTOR signaling is integral to insulin release, signaling, and beta-cell protection.
  • mTOR influences endothelial cell survival, cardiomyocyte proliferation, and cell longevity.
  • Dysregulation of mTOR can exacerbate insulin resistance in the cardiovascular system during diabetes.

Conclusions:

  • The complex role of mTOR in metabolic disease necessitates further research for therapeutic development.
  • Targeting mTOR pathways offers potential for novel strategies against diabetic cardiovascular complications.
  • A comprehensive understanding of mTOR's intricate relationship with diabetes is vital for clinical advancements.

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...

Diabetic Nephropathy

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Type I Diabetes II: Pathophysiology01:26

Type I Diabetes II: Pathophysiology

Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...
