まとめ
小分子非コードRNAであるマイクロRNA(miRNA)は遺伝子発現を調節し、細胞運命に不可欠である。その調節不全は癌と関連しており、バイオマーカーおよび治療標的としての可能性を提供する。
科学分野:
- 分子生物学; 遺伝学; 腫瘍学
背景:
- 小分子非コードRNAであるマイクロRNA(miRNA)は、遺伝子調節能力を持っています。miRNAは保存されており、組織全体で発現し、基本的な生物学的プロセスを調節しています。miRNAの調節不全は、特に癌において、様々な病状に関与しています。
研究 の 目的:
- マイクロRNAのがんへの関与に関する現在の理解をレビューすること。腫瘍発生および進行におけるmiRNAの役割を強調すること。がんバイオマーカーおよび治療薬としてのmiRNAの可能性を議論すること。
主な方法:
- 癌におけるmiRNA機能に関する研究の文献レビュー。腫瘍発生と異常なmiRNA発現を関連付ける証拠の分析。miRNAベースの診断および治療に関する現在の研究の検討。
主要な成果:
- miRNAは、がん遺伝子または腫瘍抑制遺伝子として機能することにより、癌に原因的な役割を果たしています。異常なmiRNA発現はヒト腫瘍の特徴です。miRNAは、開始から進行まで、腫瘍発生のすべての段階に関与しています。
結論:
- miRNAは癌生物学における重要な調節因子です。miRNAは、診断、予後、および予測バイオマーカーとして有望です。miRNAベースの治療法は、単独または組み合わせて癌治療の可能性のある戦略を表します。

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...
