Summary
Aberrant R-loop structures, RNA/DNA hybrids, contribute to human diseases by causing genomic instability. Understanding R-loop roles in diseases like cancer and neurological disorders is crucial for therapeutic strategies.
Area of Science:
- Molecular Biology
- Genetics
- Human Disease
Background:
- R-loops are abundant RNA/DNA hybrids formed during transcription.
- While naturally occurring and sometimes beneficial for gene regulation, aberrant R-loops can cause genomic instability.
- Persistent R-loops are linked to DNA damage, including double-strand breaks and rearrangements.
Purpose of the Study:
- To review the role of aberrant R-loop structures in human diseases.
- To discuss how mutations affecting R-loop resolution or formation contribute to disease pathology.
- To highlight specific disease examples linked to R-loop dysregulation.
Main Methods:
- Literature review and synthesis of existing research on R-loops and disease.
- Analysis of genetic mutations associated with R-loop formation and resolution.
- Categorization of diseases linked to R-loop abnormalities.
Main Results:
- Aberrant R-loops are implicated in various human diseases.
- Mutations in R-loop-related genes disrupt cellular physiology and promote disease.
- Disease categories include repeat-associated conditions, neurological disorders, and cancers.
Conclusions:
- Aberrant R-loop structures are significant contributors to human disease pathogenesis.
- Understanding the link between R-loops and mutations provides insights into disease mechanisms.
- Further research into R-loop resolution may offer therapeutic targets for associated diseases.

Non-LTR Retrotransposons
13.9K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Translation
21.5K
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.

Lysosomal Hydrolases
4.7K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Genome-wide Association Studies-GWAS
16.5K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Single Nucleotide Polymorphisms-SNPs
19.5K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
