Summary
Genomic alterations in cutaneous lymphomas (CL) were analyzed, revealing patterns that can distinguish subtypes. This meta-analysis provides a foundation for a more precise CL classification based on genomic profiles.
Area of Science:
- Genomics
- Oncology
- Bioinformatics
Background:
- Cutaneous lymphomas (CL) are extranodal non-Hodgkin lymphomas with poorly understood molecular aberrations.
- Previous genomic studies of CL present interpretation challenges due to heterogeneity.
Purpose of the Study:
- To perform a comprehensive meta-analysis of genomic alterations in various CL types.
- To propose an improved CL classification based on pathogenicity and genomic profiles.
Main Methods:
- Systematic literature search (1996-2016) for CL genome-wide copy number alteration studies.
- Utilized comparative genomic hybridization, whole-genome sequencing, and whole-exome sequencing data.
- Standardized data remapping, clustering, and visualization of copy number variation (CNV) profiles.
Main Results:
- Analyzed CNV data from 449 samples across 22 publications.
- Identified distinct patterns of structural and numerical chromosomal imbalances.
- Frequent copy number alterations (CNAs) involved key oncogenes and tumor suppressor genes.
Conclusions:
- Generated summary profiles of genomic imbalances capable of discriminating CL subtypes.
- These findings support a more accurate classification of cutaneous lymphomas.
- The analyzed data is publicly accessible via the 'Progenetix' online repository.

01:10Homeostatic Imbalance
33.7K
Homeostasis is the maintenance of a stable internal environment within the body, which is crucial for the proper functioning of cells, tissues, organs, and organ systems. The body has various control mechanisms that work together to regulate various physiological parameters such as temperature, blood pressure, pH balance, and fluid balance, to name a few. These control mechanisms are based on feedback loops that can be either positive or negative.
However, sometimes these feedback loops fail,...

01:26Imbalances in Cardiac Output
2.9K
The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

01:19Homeostatic Imbalances in Body Temperature
4.2K
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

Disorders affecting blood volume, vascular tone, or vascular function can disrupt vascular homeostasis, including conditions like hypertension, hemorrhage, and shock.
Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...

02:02DNA Topoisomerases
35.4K
Topoisomerases are enzymes that relax overwound DNA molecules during various cell processes, including DNA replication and transcription. These enzymes regulate positive and negative DNA supercoiling without changing the nucleotide sequence. DNA overwinding in a clockwise direction results in positively supercoiled DNA, whereas underwinding in a counterclockwise direction produces negatively supercoiled DNA.
Types and Mechanism of action
Topoisomerases are divided into two main types. ...

00:55DNA Helicases
24.1K
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...
