Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.8K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Mismatch Repair01:20

Mismatch Repair

5.2K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
The Mutator Protein Family Plays a Key Role in DNA Mismatch Repair
The human genome has more than 3 billion base pairs of DNA per cell. Prior to cell division, that vast amount of genetic...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

6.4K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Abnormal Proliferation02:23

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...

mTOR Signaling and Cancer Progression03:03

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...

Proteoglycans01:05

Proteoglycans

4.0K
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...

Resumen

Los patrones moleculares asociados al daño (DAMP) son señales de peligro de las células estresadas que desencadenan respuestas inmunes. Esta revisión explora los DAMP, su papel en enfermedades como el cáncer y las estrategias terapéuticas dirigidas a los DAMP y los receptores de reconocimiento de patrones (PRR).

Área de la Ciencia:

  • Inmunología
  • Biología molecular
  • Fisiopatología

Sus antecedentes:

  • Los patrones moleculares asociados al daño (DAMP) son moléculas endógenas liberadas por células estresadas o moribundas.
  • Los DAMP se unen a los receptores de reconocimiento de patrones (PRR), iniciando respuestas inmunes e inflamatorias.
  • Estos procesos son críticos en varias condiciones fisiopatológicas.

Objetivo del estudio:

  • Clasificar los DAMP en función de sus características y funciones moleculares.
  • Analizar las funciones de los DAMP en enfermedades como el cáncer, los trastornos cardiovasculares y respiratorios.
  • Revisar las estrategias terapéuticas actuales y potenciales dirigidas al eje de señalización DAMP/PRR.

Principales métodos:

  • Clasificación de los DAMP en categorías basadas en proteínas, basadas en ácido nucleico y derivadas de las mitocondrias.
  • Revisión sistemática de los mecanismos de transformación molecular, liberación y reconocimiento de DAMP.
  • Análisis en profundidad de las interacciones DAMP/PRR y las vías de señalización aguas abajo (NF-κB, MAPK, inflamatorios, cGAS-STING).

Principales resultados:

  • Los DAMP juegan un papel patológico significativo en el cáncer, las enfermedades cardiovasculares y los trastornos respiratorios.
  • Las estrategias terapéuticas actuales incluyen la modulación de la muerte celular, la neutralización de anticuerpos, los inhibidores de moléculas pequeñas y el silenciamiento de genes.
  • Los desafíos en la traducción clínica incluyen la heterogeneidad de DAMP y la administración de fármacos.

Conclusiones:

  • Dirigirse al eje DAMP / PRR ofrece posibles vías terapéuticas para el cáncer, las enfermedades neurodegenerativas, cardiovasculares y inflamatorias.
  • Las soluciones futuras pueden incluir la entrega de nanopartículas, tratamientos basados en IA y edición de genes.
  • Se necesita más investigación para superar los desafíos de traducción clínica para las terapias dirigidas a DAMP/PRR.
