Autophagic Cell Death

Autophagic Cell Death

Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and...

Overview of Cell Death

Overview of Cell Death

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...

Gene Families

Gene Families

Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

Gene Flow

Gene Flow

Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Gene Conversion

Gene Conversion

Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Area of Science:

Cardiovascular Genetics
Molecular Cardiology
Genomics

Background:

Inherited cardiac arrhythmias and sudden cardiac death (SCD) are significant causes of mortality.
Genetic mutations in ion channels and related proteins are known causes of familial arrhythmia syndromes, such as Long QT and Brugada syndromes.
However, the genetic basis for many familial arrhythmias and common arrhythmia predispositions remains largely unknown.

Purpose of the Study:

To identify novel genes responsible for inherited arrhythmia syndromes.
To investigate the genetic underpinnings of Brugada syndrome and idiopathic ventricular fibrillation.
To explore genes not previously implicated in cardiac function for their role in arrhythmias.

Main Methods:

Utilized whole exome sequencing (WES) in families affected by Brugada syndrome and idiopathic ventricular fibrillation.
Applied advanced genomic techniques to analyze genetic variations within affected families.

Main Results:

Identified mutations in genes not previously associated with cardiac arrhythmias.
Uncovered potential novel genetic contributors to Brugada syndrome and idiopathic ventricular fibrillation.
Provided new insights into the genetic landscape of inherited sudden cardiac death.

Conclusions:

Whole exome sequencing is a powerful tool for discovering novel genes in rare inherited cardiac conditions.
The identified genes may play a previously unrecognized role in cardiac electrical activity and arrhythmogenesis.
Further research into these novel genetic variants could elucidate mechanisms underlying both rare and common forms of sudden cardiac death.
