Resumen
Las células madre del adenocarcinoma pulmonar liberan vesículas extracelulares que contienen el lncRNA ROLLCSC, que mejora la resistencia a la ferroptosis de las células cancerosas al alterar el metabolismo de los lípidos. Este descubrimiento ofrece nuevos conocimientos sobre la progresión del cáncer de pulmón y posibles objetivos terapéuticos.
Área de la Ciencia:
- Oncología Oncología.
- Biología Molecular Biología Molecular
- El metabolismo del cáncer.
Sus antecedentes:
- La reprogramación metabólica es un sello distintivo del cáncer, particularmente en el cáncer de pulmón, que involucra el metabolismo lipídico relacionado con la ferroposis.
- Las células madre cancerosas (CSC) influyen en el microambiente tumoral (TME), pero su papel en la reprogramación metabólica del adenocarcinoma pulmonar (LUAD) no está claro.
Objetivo del estudio:
- Investigar el papel de los ARN largos no codificantes (ARNlnc) derivados de la vesícula extracelular (EV) de las células madre LUAD en la regulación de la EMT y la reprogramación metabólica.
- Para aclarar el mecanismo por el cual lncRNA ROLLCSC influye en el metabolismo de los lípidos y la resistencia a la ferroptosis en las células LUAD.
Principales métodos:
- La secuenciación del ARN (ARN-seq)
- La proteómica es la proteómica.
- Los ensayos de retiro del ARN en ensayos de retiro del ARN.
- La reacción en cadena de la polimerasa (PCR, por sus siglas en inglés)
- Experimentos de biología molecular experimentos de biología molecular.
Principales resultados:
- El lncRNA ROLLCSC identificado de los EV derivados del LUAD CSC regula el TME.
- Se descubrió que ROLLCSC interactúa con CDC42, promoviendo la absorción y estabilidad de EV a través de la desmetilación mediada por FTO y el reconocimiento de IGF2BP2.
- Se ha demostrado que ROLLCSC remodela el metabolismo lipídico de la célula receptora de cáncer de pulmón (LLC) al dirigirse a ACSL4 y Slc25a11, mejorando la resistencia a la ferroposis.
Conclusiones:
- El lncRNA ROLLCSC de los EV derivados del CSC se transporta de manera eficiente a las células LUAD, reprogramando su metabolismo lipídico y aumentando la resistencia a la ferroposis.
- ROLLCSC y sus objetivos muestran patrones de expresión tumoral distintos y poseen un significado pronóstico en LUAD.
- Este estudio revela un nuevo mecanismo de comunicación intercelular y regulación metabólica en la progresión de la LUAD.

02:39lncRNA - Long Non-coding RNAs
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
02:07Tumor Progression
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...

02:17The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
03:03mTOR Signaling and Cancer Progression
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.
