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:

Area of Science:

  • Genetics
  • Molecular Biology
  • Neurology

Background:

  • Tuberous sclerosis complex (TSC) is a genetic disorder affecting multiple organs.
  • It is caused by mutations in TSC1 or TSC2 genes, leading to hamartoma formation.
  • The hamartin-tuberin complex normally inhibits the mTOR pathway, regulating cell growth.

Purpose of the Study:

  • To review the genetic basis and molecular mechanisms of TSC.
  • To highlight the clinical manifestations, particularly central nervous system (CNS) complications.
  • To discuss the therapeutic potential of targeting the mTOR pathway.

Main Methods:

  • Literature review of genetic and molecular studies on TSC.
  • Analysis of clinical data on TSC patient cohorts.
  • Examination of the role of the mTOR pathway in TSC pathogenesis.

Main Results:

  • TSC is linked to TSC1/TSC2 gene mutations and mTOR pathway dysregulation.
  • CNS complications, including epilepsy and cognitive issues, affect ~85% of pediatric patients.
  • Tumor development and clinical variability are influenced by lesion characteristics.

Conclusions:

  • Targeting the upregulated mTOR pathway offers a promising therapeutic strategy for TSC.
  • Further understanding of TSC molecular abnormalities can improve disease management.
  • Personalized treatment approaches may be developed based on genetic and molecular profiles.
