Summary
Studying rare genetic disorders like Rett syndrome (RTT) and tuberous sclerosis complex (TSC) in animal models reveals neurodevelopmental mechanisms. This research is paving the way for new autism and epilepsy treatments in humans.
Area of Science:
- Neuroscience
- Genetics
- Developmental Biology
Background:
- Rare genetic disorders, including Rett syndrome (RTT) and tuberous sclerosis complex (TSC), manifest with autism, epilepsy, and intellectual disability.
- These Mendelian disorders offer unique insights into neurodevelopmental disorder mechanisms.
Purpose of the Study:
- To review advances in understanding RTT and TSC pathogenesis.
- To identify signaling pathways for novel therapeutic targets.
- To highlight the translation of animal model findings to human clinical trials.
Main Methods:
- Examination of animal models engineered with mutant forms of mouse homologs of human RTT and TSC genes.
- Dissection of molecular pathology using these models.
- In-vivo assays of therapeutic strategies in animal models.
Main Results:
- Animal models have enabled the dissection of molecular pathology in RTT and TSC.
- Therapeutic strategies tested in animal models have successfully translated to human clinical trials.
- Progress in understanding RTT and TSC pathogenesis is accelerating.
Conclusions:
- Single-gene disorders serve as powerful models for studying neurodevelopmental disorders.
- These models facilitate research into the roles of specific molecules and pathways in autism, epilepsy, and cognitive impairment.
- Research on RTT and TSC is driving the development of disease-modifying therapies for autism and related conditions.

01:31Translation
Lesson: Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

01:20The 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,...

01:27Post-translational Translocation of Proteins to the RER
A sizable fraction of proteins destined for ER are first synthesized in the cell cytosol and then transported across the ER membrane–a process called post-translational translocation. Similar to cotranslationally translocated proteins, these proteins also use the Sec translocon complex to enter the ER lumen.
Targeting proteins to the ER
Hsp40 and Hsp70 chaperone molecules bind the translated proteins in the cytosol to prevent their folding. The chaperone binding helps to keep the signal...

01:21Smooth Endoplasmic Reticulum
Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...
