Summary
Human papillomaviruses (HPV) cause cervical and other cancers by manipulating differentiated epithelial cells. This review details how HPV utilizes cellular pathways to replicate within these specialized cells.
Area of Science:
- Virology
- Cell Biology
- Oncology
Background:
- Human papillomaviruses (HPV) are linked to cervical, genital, and head and neck cancers.
- HPV infects stratified epithelia, with genome maintenance in basal cells and productive replication in differentiated cells.
Purpose of the Study:
- To review how HPV interacts with cellular signaling pathways.
- To explain how HPV creates a replication-competent environment in differentiating epithelial cells.
Main Methods:
- Literature review of HPV life cycle and cellular interactions.
- Analysis of signaling pathways exploited by HPV.
Main Results:
- HPV infection requires distinct cellular environments for genome maintenance and productive replication.
- HPV hijacks cellular differentiation pathways to facilitate viral replication and virion production.
- Specific cellular signaling pathways are modulated by HPV to support its life cycle in non-proliferating cells.
Conclusions:
- HPV has evolved sophisticated mechanisms to exploit cellular differentiation.
- Understanding HPV's interaction with cellular signaling is crucial for developing targeted therapies against HPV-associated malignancies.

02:38S-Cdk Initiates DNA Replication
5.8K
The cell cycle is a series of events leading to DNA duplication followed by the division of cell content to form two daughter cells. The cell cycle progresses in four stages—the cell increases in size (gap 1 or G1-phase), duplicates its DNA (synthesis or S-phase), prepares to divide (gap 2 or G2-phase), and divides (mitosis or M-phase).

01:12Renewal of Skin Epidermal Stem Cells
3.1K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

01:51Mechanisms of Retrovirus-induced Cancers
7.1K
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...

03:17Inheritance of Chromatin Structures
7.7K
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

00:55DNA Helicases
24.4K
DNA unwinding helicase enzymes are a type of motor protein. Motor proteins can translocate along filaments or polymers using energy generated from ATP hydrolysis. Helicases are involved in all the important cellular processes where DNA unwinding is required, such as DNA replication, repair, recombination, and transcription. They are present in all living organisms, but vary in their structure, function, and mechanism of action. For example, in prokaryotes, DnaB helicase binds and translocates...

02:37Restarting Stalled Replication Forks
6.4K
DNA replication is initiated at sites containing predefined DNA sequences known as origins of replication. DNA is unwound at these sites by the minichromosome maintenance (MCM) helicase and other factors such as Cdc45 and the associated GINS complex.The unwound single strands are protected by replication protein A (RPA) until DNA polymerase starts synthesizing DNA at the 5’ end of the strand in the same direction as the replication fork. To prevent the replication fork from falling apart,...
