Insights

The Tuberous Sclerosis Complex-mammalian target of rapamycin (TSC-mTOR) pathway regulates cell growth. Its dysregulation is linked to tumors and metabolic disorders like diabetes.

Area of Science:

  • Biochemistry
  • Cell Biology
  • Molecular Biology

Background:

  • The mammalian target of rapamycin (mTOR) pathway, comprising TORC1 and TORC2 complexes, is vital for cell growth, survival, translation, transcription, and autophagy.
  • Tuberous Sclerosis Complex (TSC) proteins, TSC1 and TSC2, act as tumor suppressors by inhibiting TORC1 activity.
  • Mutations in TSC1 or TSC2 lead to TSC disease, characterized by hamartomas.

Purpose of the Study:

  • To explore the multifaceted roles of the TSC-mTOR pathway beyond tumor development.
  • To investigate the involvement of mTOR signaling in appetite, memory, aging, and energy metabolism.
  • To understand the implications of TSC-mTOR pathway dysregulation in metabolic disorders such as diabetes.

Main Methods:

  • Literature review of studies on TSC-mTOR signaling.
  • Analysis of research on mTOR's role in cellular processes and disease.
  • Examination of the connection between TSC-mTOR pathway and metabolic regulation.

Main Results:

  • The TSC-mTOR pathway is a critical regulator of cell growth and survival.
  • Dysregulation of this pathway contributes to both tumor formation and metabolic diseases.
  • Emerging evidence highlights mTOR's influence on appetite, memory, aging, and energy metabolism.

Conclusions:

  • The TSC-mTOR pathway is implicated in a broader range of physiological processes than previously understood.
  • Understanding TSC-mTOR signaling is crucial for addressing both cancer and metabolic disorders.
  • Further research into the TSC-mTOR pathway may reveal novel therapeutic targets for TSC disease and diabetes.

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...

Type II Diabetes II: Pathophysiology

PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.
Type II Diabetes I: Introduction01:26

Type II Diabetes I: Introduction

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...
