Resumen

Décadas de investigación sobre las proteínas de la familia BCL-2 condujeron al desarrollo de inhibidores de BCL-2, revolucionando el tratamiento del cáncer al dirigirse a la apoptosis. Comprender los mecanismos de resistencia y explorar nuevas vías terapéuticas son clave para el progreso futuro en la terapia contra el cáncer.

Área de la Ciencia:

Biología del Cáncer
Biología Molecular
Inmunología

Sus antecedentes:

La familia de proteínas BCL-2 regula la apoptosis, un proceso crucial en la muerte celular.
La desregulación de BCL-2 contribuye a la patogénesis del cáncer, particularmente en las neoplasias malignas linfoides.
La permeabilización de la membrana externa mitocondrial (MOMP) es un evento clave en la apoptosis regulada por BCL-2.

Objetivo del estudio:

Revisar el viaje desde el descubrimiento de BCL-2 hasta el desarrollo de inhibidores clínicos.
Discutir los mecanismos de BCL-2 en la regulación de la apoptosis y su papel en el cáncer.
Explorar los desafíos, los mecanismos de resistencia y las direcciones futuras en la terapia dirigida a BCL-2.

Principales métodos:

Revisión de la literatura sobre la investigación de BCL-2, que abarca desde la ciencia básica hasta las aplicaciones clínicas.
Análisis de las interacciones de la familia BCL-2 y su papel en la apoptosis.
Examen de datos clínicos de inhibidores de BCL-2 como el venetoclax en neoplasias hematológicas.

Principales resultados:

Los inhibidores de BCL-2, como el venetoclax, han mostrado un éxito significativo en el tratamiento de la leucemia linfocítica crónica (LLC) y la leucemia mieloide aguda (LMA).
La resistencia a los inhibidores de BCL-2 puede surgir de mutaciones en BCL-2 o de la regulación al alza de otras proteínas antiapoptóticas como MCL-1.
La MOMP subletal puede desencadenar respuestas inflamatorias, ofreciendo objetivos terapéuticos alternativos.

Conclusiones:

La diana de BCL-2 ha transformado la terapia contra el cáncer, especialmente para los cánceres hematológicos.
Superar la resistencia y ampliar la eficacia de los inhibidores de BCL-2 a los tumores sólidos siguen siendo desafíos importantes.
La investigación futura debe centrarse en nuevos inhibidores, terapias combinadas y la comprensión de los roles no apoptóticos de BCL-2.

The Intrinsic Apoptotic Pathway

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

PI3K/mTOR/AKT Signaling Pathway

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

Combination Therapies and Personalized Medicine

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Targeted Cancer Therapies

Targeted Cancer Therapies

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...

NF-κB-dependent Signaling Pathway

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Abnormal Proliferation

Abnormal Proliferation

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...
