- Oncología Oncología.
Sus antecedentes:
- Los pequeños ARN no codificantes, los microARN (miRNA), poseen capacidad de regulación génica.
- Los miARN se conservan, se expresan en los tejidos y regulan los procesos biológicos fundamentales.
- La desregulación del miRNA está implicada en varias afecciones patológicas, especialmente el cáncer.
Objetivo del estudio:
- Revisar la comprensión actual de la participación del microARN en el cáncer.
- Para resaltar el papel de los miRNA en la tumorigénesis y la progresión.
- Discutir el potencial de los miRNA como biomarcadores del cáncer y agentes terapéuticos.
Principales métodos:
- Revisión de la literatura de estudios sobre la función del miRNA en el cáncer.
- Análisis de la evidencia que vincula la expresión aberrante de miRNA con el desarrollo de tumores.
- Examen de las investigaciones actuales sobre diagnósticos y terapias basadas en miRNA.
Principales resultados:

MicroRNAs
24.3K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

Antigens Involved in Adaptive Immunity
1.6K
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Cancer
54.5K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

What is Cancer?
14.5K
Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.

Cancer Vaccines
1.1K
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
