まとめ

RASタンパク質は細胞の成長とホメオスタシスに不可欠ですが癌を誘発します複雑な役割と信号伝達経路を理解することは効果的ながん治療法の開発の鍵です

科学分野:

分子生物学
腫瘍学
遺伝学

背景:

RASスーパーファミリーのプロトオンコゲンは,成長信号を調節する細胞ホメオスタシスにとって不可欠です.
RASプロトオンコゲンをインビトロで活性化すると,細胞が遺伝子調節における役割を強調します.
広範な研究にも関わらず,RAS変異によって引き起こされる進行がんは,依然として知識のギャップを示しています.

研究の目的:

RAS遺伝子とタンパク質が細胞の恒常性と腫瘍形成における二重の役割を検討する.
RAS機能のヒト,マウス,ドロソフィラモデルからの洞察を統合する.
RAS遺伝子の調節とタンパク質の機能に関する現在の知識を,正常な状況と腫瘍学的状況の両方で統合する.

主な方法:

RAS遺伝子とタンパク質に関する既存の文献の記述的レビュー.
人間 (HRAS, KRAS, NRAS),マウス (Hras, Kras, Nras),ドロソフィラ (ras) モデルからのデータの統合.
ゲノム変異から細胞外相互作用までのRAS機能の検討.

主要な成果:

RASタンパク質は,細胞の成長,アポトーシス,そしてタンパク質の密輸を含む重要な管理機能を持っています.
RAS変異はヒトの腫瘍と強く関連しているが,その腫瘍性機能は複雑である.
RASによって誘発される異なるがん経路 (MAPK,PI3K) は,様々な病気の進行と治療課題につながる可能性があります.

結論:

正常なRAS機能と腫瘍学的役割の相互作用は複雑で組織特異的です.
先進的な癌は異質性や薬剤耐性や適応性といった課題を抱えています
RAS経路の層次的な理解は,家庭管理と腫瘍遺伝的文脈の両方でその役割を扱うために不可欠です.

The Ras Gene

6.4K

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.

Small GTPases - Ras and Rho

4.2K

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:

Cancer-Critical Genes I: Proto-oncogenes

9.1K

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Abnormal Proliferation

4.6K

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Rous Sarcoma Virus (RSV) and Cancer

5.4K

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

mTOR Signaling and Cancer Progression

3.9K

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
