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...

Resumen

El rasgo de células falciformes (SCT) no aumenta el riesgo general de cáncer. Sin embargo, la SCT puede ofrecer protección contra la leucemia y muestra un vínculo potencial pero no concluyente con un mayor riesgo de cáncer renal.

Área de la Ciencia:

  • Hematología
  • En el campo de la oncología
  • Epidemiología

Sus antecedentes:

  • El rasgo de células falciformes (SCT) es una condición hereditaria común, a menudo considerada benigna.
  • Las investigaciones emergentes sugieren un posible vínculo entre SCT y el desarrollo del cáncer.
  • Comprender esta asociación es crucial para la salud pública, especialmente en las poblaciones en riesgo.

Objetivo del estudio:

  • Investigar la asociación entre el rasgo de células falciformes (SCT) y el riesgo de desarrollar mieloma múltiple, cáncer renal, leucemia, carcinoma hepatocelular (HCC) y cáncer colorrectal.
  • Evaluar la incidencia del cáncer y los resultados de supervivencia en individuos con SCT.
  • Aclarar el papel oncogénico o protector de la SCT en diversas neoplasias malignas.

Principales métodos:

  • Análisis retrospectivo de cohorte de registros electrónicos de salud no identificados de la base de datos TriNetX durante 20 años.
  • Evaluación estadística utilizando la diferencia de riesgo (RD), el coeficiente de riesgo (RR), el coeficiente de probabilidad (OR) y los coeficientes de riesgo (HR).
  • Análisis de supervivencia Kaplan-Meier para evaluar los resultados del cáncer en pacientes con SCT y enfermedad de células falciformes (SCD).

Principales resultados:

  • El rasgo de células falciformes (SCT) no se relacionó con un mayor riesgo de mieloma múltiple, CHC o cáncer colorrectal.
  • Se observó un riesgo estadísticamente menor de leucemia en individuos con SCT en comparación con pacientes con SCD (RR=0,464, p<0,001), lo que sugiere un efecto protector.
  • Se observó un aumento modesto y no significativo en el riesgo de cáncer renal en individuos con SCT (RR=1,201, p=0,059).

Conclusiones:

  • El rasgo de células falciformes (SCT) no eleva el riesgo general de cáncer.
  • La SCT puede conferir un efecto protector contra la leucemia, potencialmente a través de mecanismos inmunológicos o hematopoyéticos.
  • Se necesitan más investigaciones para confirmar la asociación observada con el cáncer renal y aclarar las vías biológicas subyacentes.
