Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

1.4K
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Human Genetics

2.0K
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Retroviruses02:33

Retroviruses

12.2K
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Non-LTR Retrotransposons03:18

Non-LTR Retrotransposons

12.5K
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...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

43.1K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Mechanisms of Retrovirus-induced Cancers

5.2K
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Area of Science:

  • Neuroscience
  • Genetics
  • Immunology

Background:

  • Human endogenous retroviruses (HERVs) are implicated in complex diseases.
  • Attention Deficit Hyperactivity Disorder (ADHD) involves genetic and environmental factors.
  • The role of HERVs in neurodevelopmental disorders like ADHD is under investigation.

Purpose of the Study:

  • To analyze the expression levels of HERV-H, HERV-K, and HERV-W families in ADHD patients.
  • To explore the potential link between HERV expression and ADHD.

Main Methods:

  • Quantitative RT-PCR was used to measure retroviral mRNA expression.
  • Peripheral blood mononuclear cells (PBMCs) were analyzed from 30 ADHD patients and 30 healthy controls.

Main Results:

  • Significantly higher expression levels of HERV-H were observed in ADHD patients compared to healthy controls.
  • No significant differences in expression levels were found for HERV-K and HERV-W families.

Conclusions:

  • HERV-H overexpression may represent a link between genetic/environmental factors and the ADHD phenotype.
  • HERV-H could potentially serve as a novel biomarker for ADHD.
  • Further research in larger cohorts is needed to confirm the role of HERVs in neurodevelopmental diseases.
