Summary
Endogenous retroviruses (ERVs) play key roles in development and immunity. This study found ERVH48-1 enhances somatic cell reprogramming, generating induced pluripotent stem cells (iPSCs) capable of differentiating into all germ layers.
Area of Science:
- Genomics
- Developmental Biology
- Immunology
Background:
- Endogenous retroviruses (ERVs) were once considered junk DNA.
- ERVs are now known to be crucial for embryonic development, innate immunity, and cancer.
- Their evolutionary impact on host genomes is significant.
Purpose of the Study:
- To investigate the functional roles of ERVs in human cells.
- To explore ERV expression patterns in different cell types.
- To determine ERV involvement in somatic cell reprogramming.
Main Methods:
- Analysis of single-cell transcriptomic profiles from human embryonic stem cells and urine cells.
- Investigating ERVH48-1 expression patterns.
- Overexpression of ERVH48-1 in a urine cell-reprogramming system.
Main Results:
- A unique ERVH48-1 expression pattern was identified between embryonic stem cells and urine cells.
- Overexpression of ERVH48-1 significantly enhanced somatic cell reprogramming efficiency.
- Induced pluripotent stem cells (iPSCs) generated via ERVH48-1 overexpression exhibited pluripotency and differentiated into all three germ layers in vitro.
Conclusions:
- Endogenous retroviruses, specifically ERVH48-1, play a functional role in somatic cell reprogramming.
- ERVs can be leveraged to improve the generation of induced pluripotent stem cells.
- This research highlights a novel application of ERVs in regenerative medicine.

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’...

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...

LTR retrotransposons are class I transposable elements with long terminal repeats flanking an internal coding region. These elements are less abundant in mammals compared to other class I transposable elements. About 8 percent of human genomic DNA comprises LTR retrotransposons. Some of the common examples of LTR retrotransposons are Ty elements in yeast and Copia elements in Drosophila.

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...
