Resumen
El cáncer colorrectal (CCR) surge de una renovación alterada de las criptas del colon. Una tasa de polimerización celular más lenta debido a mutaciones de APC causa desorganización tisular y formación de adenomas.
Área de la Ciencia:
- Biología celular
- Modelado computacional
- Investigación del cáncer
Sus antecedentes:
- La organización del epitelio del colon sigue cinco reglas biológicas.
- La tumorigénesis del colon puede implicar la renovación tisular autocatalítica.
Objetivo del estudio:
- Definir cómo la alteración del recambio de criptas impulsa la morfogénesis del adenoma y el cáncer colorrectal (CCR).
- Investigar la relación entre la tasa de renovación tisular y la expansión epitelial.
Principales métodos:
- Desarrollo de un modelo computacional del epitelio del colon como un polímero celular.
- Uso de ecuaciones diferenciales no lineales para simular la dinámica de la población de células de cripta.
- Análisis de las proporciones de tipos de células durante el desarrollo de adenomas en pacientes con P.A.F.
Principales resultados:
- Las criptas del colon premalignas presentan tasas de renovación tisular disminuidas.
- La mutación de APC se asocia con esta tasa de renovación reducida.
- La polimerización celular más lenta actúa como un paso limitante de la velocidad, expandiendo las células proliferativas.
Conclusiones:
- Una tasa de renovación de criptas prolongada explica la desorganización tisular en la formación de adenomas.
- Este mecanismo implica expansión epitelial local, plegamiento y contorsión.
- Proporciona información sobre los orígenes del cáncer colorrectal.

Renewal of Intestinal Stem Cells
3.1K
The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...

Renewal of Skin Epidermal Stem Cells
3.0K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.4K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Metastasis
6.4K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Tumor Progression
7.2K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Adaptive Mechanisms in Cancer Cells
6.9K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
