Cancers Originate from Somatic Mutations in a Single Cell

12.6K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Cancer-Critical Genes II: Tumor Suppressor Genes

7.9K
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...

The Retinoblastoma Gene

4.2K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Cancer Stem Cells and Tumor Maintenance

5.0K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

科学分野:

  • 血液学
  • 腫瘍学
  • 流行病学

背景:

  • シークル細胞特質 (SCT) は一般的な遺伝性疾患で,しばしば良性と考えられています.
  • 新興の研究では SCTと癌の発症との関連が示唆されています
  • この関連性を理解することは公衆衛生,特にリスクの高い集団にとって極めて重要です.

研究 の 目的:

  • 状細胞特性 (SCT) と多発性骨髄腫,腎臓がん,白血病,肝細胞癌 (HCC),大腸がんの発症リスクとの関連を調査する.
  • SCT患者におけるがん発生率と生存結果を評価する.
  • 様々な悪性腫瘍におけるSCTの腫瘍発生性または保護的役割を明らかにする.

主な方法:

  • トリネットXデータベースから 20年以上に渡って取り消された電子医療記録の遡及コホート分析
  • リスク差 (RD),リスク比 (RR),オッズ比 (OR),危険比 (HR) を用いた統計的評価
  • SCTおよび状細胞疾患 (SCD) の患者のがんアウトカムを評価するためのKaplan- Meier生存分析.

主要な成果:

  • 状細胞特性 (SCT) は多発性骨髄腫,HCC,または結腸直腸がんのリスク増加と関連していません.
  • SCD患者と比較して,SCT患者では統計的に有意な白血病のリスクの低下が観察された (RR=0. 464,p< 0. 001),これは保護効果を示唆している.
  • SCT患者では,腎臓がんのリスクがわずかに増加した (RR=1. 201,p=0. 059).

結論:

  • 状細胞特性 (SCT) は全体的ながんリスクを高めません.
  • SCTは,免疫的または造血的メカニズムを通じて,白血病に対する保護効果を与える可能性があります.
  • 腎臓がんと観察された関連性を確認し,基礎となる生物学的経路を明らかにするために,さらなる研究が必要である.
