- ゲノミクスゲノミクスとは
- がん生物学 がん生物学
- バイオインフォマティックス
背景:
- バイオマーカーは,がんのスクリーニング,早期発見,モニタリングに不可欠です.
- ヌーロメアはゲノム配列が欠けていて,ネオメアは癌変異から生じるサブセットです.
研究 の 目的:
- 様々ながんタイプと臓器におけるネオマーに関する包括的なデータベースであるネオマーDBを開発する.
- 特定のがんや臓器に関連するネオマーを特定し,分類する.
- 癌のバイオマーカーとしてネオマーを利用するためのリソースを提供すること.
主な方法:
- 腫瘍にマッチした1万の全エクソームと2,658の全ゲノムサンプルを分析し,がん特異のネオマーを特定しました.
- 76,215の全ゲノムと7,300,947の全エクソームを調査し,生殖系から派生したヌロマーとネオマーをフィルターしました.
- 先進的な検索,視覚化,ダウンロード機能を備えた neomerDB を開発しました.
主要な成果:
- 異なるがんタイプと臓器に特異的なネオメアのカタログを特定しました.
- フィルタリングされた集団特有のヌーロマーと,生殖系変異から生じるネオマー.
- 液体生検 (cfDNA,cfRNA) から高精度で (AUC 0.98,Precision-Recall 0.99) グリオブラストーマを検出する際のネオメルの有用性が実証されています.
結論:
- NeomerDBは,がんバイオマーカーの発見と研究のための貴重なリソースを提供します.

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.

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.

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

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...
