Microtubules in Signaling01:22

Microtubules in Signaling

The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...
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.
The mTOR pathway or the...
PI3K/mTOR/AKT Signaling Pathway01:22

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...
Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Summary
This summary is machine-generated.

Tuberous sclerosis is a genetic disorder causing tumors in multiple organs due to mutations in TSC1 and TSC2 genes. Understanding these molecular changes is key for managing severe cases and improving patient outcomes.

Area of Science:

  • Genetics
  • Molecular Biology
  • Medical Science

Background:

  • Tuberous sclerosis is a genetic multisystem disorder characterized by hamartomas in organs like the brain, heart, skin, and kidneys.
  • It is caused by mutations in the TSC1 and TSC2 genes, which encode hamartin and tuberin.
  • The hamartin-tuberin complex normally inhibits the mammalian-target-of-rapamycin (mTOR) pathway, crucial for cell growth.

Purpose of the Study:

  • To summarize the genetic basis and clinical manifestations of tuberous sclerosis.
  • To highlight the role of the TSC1/TSC2-hamartin-tuberin-mTOR pathway.
  • To emphasize the need for early identification of patients at risk for severe disease.

Main Methods:

  • Review of existing literature on tuberous sclerosis genetics and clinical presentation.
  • Analysis of the molecular mechanisms involving TSC1, TSC2, and the mTOR pathway.
  • Discussion of diagnostic challenges and the importance of risk stratification.

Main Results:

  • Tuberous sclerosis results from genetic mutations affecting cell growth regulation.
  • Clinical presentation varies widely due to lesion distribution and genetic factors.
  • Current diagnostic methods are limited for early detection as symptoms appear after age three.

Conclusions:

  • Understanding the molecular basis of tuberous sclerosis is essential for developing targeted therapies.
  • Early identification of at-risk individuals is critical for managing severe manifestations.
  • Further research into molecular abnormalities may lead to improved disease management strategies.
