The combination of fasting and chemotherapy improves the response against cancer, with differences according to sex.
The team led by Dr. Pablo José Fernández-Marcos has conducted pioneering research focused on the impact on the immune system of combining fasting and chemotherapy and bringing this strategy to the fight against cancer. The results show how hormonal factors can modulate the body's response to these therapies.
This finding opens up new avenues in considering sex as a crucial factor in the design of personalized therapies to combat the disease. The work has involved a multidisciplinary team made up of researchers from IMDEA Alimentación, led by Dr. Andrés Pastor-Fernández, and the participation of centers such as the CBM and CNIO, the CEU San Pablo University and the Spanish Association Against Cancer.
Madrid, April 18, 2024
The recent study led by a team of researchers from Institute IMDEA Food represents a significant milestone in the field of cancer therapies, demonstrating the positive immunological effects of fasting together with chemotherapies such as doxorubicin or oxaliplatin. For the first time, variations in this process are observed according to sex, especially in the melanoma model and with testosterone as a relevant factor, which has important clinical implications.
One of the main findings is the identification of 'sexual dimorphism' in the immune responses induced by the combination of fasting and chemotherapy: it is more pronounced in males than in females, following the study in mice. This phenomenon appears prominently in a melanoma model, yet no gender differences in response are observed in a colorectal adenocarcinoma model, suggesting a remarkable complexity in the interaction between treatments and different types of disease. This finding highlights the importance of considering sex as a crucial factor in the design of personalized therapeutic strategies to combat cancer.
The results show how fasting increases the presence of Natural Killer and Natural Killer T cells in melanoma and CD8 lymphocytes in colorectal adenocarcinoma, when administered together with chemotherapy. The research extends two previous studies by the Metabolic Syndrome Group at IMDEA Alimentación, which had already found the ability of short-term fasting to modulate several novel biomarkers related to protection from chemotherapy toxicity. In another work, they also showed the increase of p21 protein when combining fasting and chemotherapy with two consequences: protection against toxicity in metabolically relevant tissues (kidney, liver and heart), and a better efficacy of treatment against colorectal adenocarcinoma.
This latest work, which has been published in Cancer Communications, has involved leading researchers from the Severo Ochoa Molecular Biology Center (CBM), the Spanish National Cancer Research Center (CNIO) and the San Pablo CEU University. It has also received financial support from the Spanish Association Against Cancer (AECC).
Sexual dimorphism in the response to fasting
One of the objectives of this work has been to investigate how sex influences the effects of combining fasting and chemotherapy in the fight against cancer. To this end, tests have been carried out on male and female mice with melanoma. Molecular biologist Pablo José Fernández-Marcos, leader of the research, stresses that the investigation reveals what is known as "sexual dimorphism in the response to fasting" which, as he advances, "has significant translational implications, especially in tumors such as melanoma, where testosterone, the male sex hormone, plays a crucial role in the effects of fasting".
In the study of different cancer models, the researchers have observed different immune responses and, therefore, "the improvement of chemotherapy with fasting may not depend on a specific type of immune cell". Dr. Fernandez-Marcos points out that the interactions between immune cells in different tissues, such as the tumor, peripheral blood and nearby lymph nodes, are extremely complex. In the B16-F10 melanoma model, it has been observed that certain cells (Natural Killer and Natural Killer T cells) are particularly effective when fasting is combined with chemotherapy. In addition, CD8 lymphocytes also play an important role in the differences observed between sexes in this model.
On the other hand, in a model of colon adenocarcinoma (MC38), the team has found an increase in the combination of fasting and chemotherapy in the number of effector CD8 T lymphocytes and CD4 Th1 lymphocytes within the tumor, with antitumor properties. In contrast to the previous melanoma model, the fasting-enhanced response occurs in both male and female mice. In addition, the researchers have observed a significant decrease in the number of macrophages in the tumor, which exhibit protumorigenic properties. These findings show the "complexity of the immune response in different types of cancer" and suggest that the combination of fasting and chemotherapy may be a promising strategy to improve the efficacy of cancer treatment.
This work, with important clinical implications, has been made possible by the work of a multidisciplinary team in which, in addition to Dr. Pablo José Fernández-Marcos and Dr. Andrés Pastor-Fernández, Dr. Cristina Pantoja, Dr. Marta Barradas, Dr. Adrián Plaza, Dr. José Luis López-Aceituno, from Institute IMDEA Alimentación, Dr. María Mittelbrunn, Manuel Manuel Mittelbrunn, Dr. Manuel Mittelbrunn, and Dr. María Mittelbrunn, from Institute IMDEA Alimentación, have participated in the study. María Mittelbrunn, Manuel Montero and Ignacio Escrig-Larena, from the Severo Ochoa Molecular Biology Center (CSIC-UAM); as well as Lola Martínez and Dr. Alejo Efeyán, from the Spanish National Cancer Research Center (CNIO); and Dr. Esther Durán, from the CEU San Pablo center.
The group led by Dr. Fernández-Marcos has excelled in research on nutritional interventions focused on fasting. Their studies have explored the effects of fasting on aging, obesity, diabetes and cancer, using cellular models, animal models and human trials. His main lines of research include high-throughput screens to identify bioactive products that mimic the benefits of fasting, the ability of fasting to potentiate cancer chemotherapy treatments, and a human clinical trial to study the mechanisms driving the protective effects of fasting against the side effects of chemotherapy. These investigations promise to contribute significantly to the field of nutrition and health, offering new insights into the treatment of various diseases.

Un estudio liderado por el grupo de Miguel Manzanares, analiza los factores que otorgan plasticidad a las células pluripotentes y su papel en la elección de los linajes celulares
15/07
Pluripotent cells are a transient population present in the early mammalian embryo dependent on transcription factors, such as OCT4 and NANOG, which maintain pluripotency while simultaneously suppressing lineage specification. Interestingly, these factors are not exclusive to uncommitted cells, but are also expressed during early phases of differentiation. However, their role in the transition from pluripotency to lineage specification is largely unknown. Using genetic models for controlled Oct4 or Nanog expression during postimplantation stages, we found that pluripotency factors play a dual role in regulating key lineage specifiers, initially repressing their expression and later being required for their proper activation. We show that the HoxB cluster is coordinately regulated in this way by OCT4 binding sites located at the 3’ end of the cluster. Our results show that core pluripotency factors are not limited to maintaining the pre-committed epiblast, but are also necessary for the proper deployment of subsequent developmental programs.

Entrevistamos a María Llorens-Martín, científico titular del CSIC en el Centro de Biología Molecular Severo Ochoa e Investigadora Principal de un proyecto Consolidator Grant del Consejo Europeo de Investigación (ERC)
Estudia el fenómeno de neurogénesis (generación de nuevas neuronas) hipocampal adulta en el ser humano y en modelos animales ¿Puede explicarnos en qué consiste? ¿Qué papel juega el hipocampo?
La neurogénesis adulta consiste en el nacimiento de nuevas neuronas en la vida adulta. En nuestro laboratorio estudiamos este proceso en el cerebro de los mamíferos. Más específicamente, estamos centrados en estudiar el nacimiento de nuevas neuronas en una región concreta del cerebro, el hipocampo. Esta región participa de manera clave en la adquisición de nuevas memorias y también en la regulación del estado de ánimo y las emociones.

Margarita del Val: “A veces he sido un poco coñazo”
17/03
La viróloga analiza su salto a los medios durante la pandemia y cómo ha cambiado la ciencia en estos dos años.
“Pensé que era mi responsabilidad, que era un reto que debía aceptar. Para el viernes antes de confinarnos yo ya estaba pringada”, recuerda la viróloga Margarita del Val dos años después de que todo estallara. Marga, como la conocen en su entorno, entró a partir de ese momento en las casas españolas para hacernos sentir “más seguros dentro de la incertidumbre” de la pandemia de covid. Su imagen se polarizó, como todo en esta crisis, y mientras unos veneraban sus consejos, otros maldecían sus advertencias. Ahora, tras un máster maratoniano de comunicación de riesgos, Del Val (Madrid, 62 años) sigue al frente de la plataforma de Salud Global del CSIC, la más grande de la mayor institución científica española. Y reconoce entre risas que no va a echar de menos a los medios cuando todo se calme, después de dos años presente en todos los informativos del país.
Maria Mittelbrunn, group leader at the Centro de Biologia Molecular, has been awarded with ERC Consolidator Grant
17/03
The European Research Council (ERC) has awarded Consolidator Grant to Dr. Maria Mittelbrunn´s Lab to support their research for 5 years.
The project focus on the delay of age-related diseases by interfering with T cells.
Maria Mittelbrunn, a scientist from the Consejo Superior de Investigaciones Cientificas (CSIC),and head of the “Immunometabolism & Inflammation lab” at the Centro de Biología Molecular Severo Ochoa, has been awarded with the prestigious Consolidator Grant of the European Research Council (ERC), which is endowed with 2 million euros. Today, The European Research Council (ERC) has announced the award of its Consolidator Grants to 313 group leaders throughout Europe, 33 of them in Spain. The award aims to support the most talented scientists in Europe to give them the freedom to pursue their ideas.
Prof. Maria Leptin, President of the ERC said: ”Even in times of crisis and conflict and suffering, it is our duty to keep science on track and give our brightest minds free reign to explore their ideas. We do not know today how their work might revolutionise tomorrow - we do know that they will open up new horizons, satisfy our curiosity and most likely help us prepare for unpredictable future challenges”
Ageing is one of the fundamental challenges facing our society. Mittelbrunn wants to identify common molecular mechanisms that drive many diseases in old age. In her ERC-funded project “LetTBe” she will investigate whether we can delay aging and age-related diseases by targeting immune cells.
“It is an immense honour to receive this Grant. This funding will enable me to massively expand our research on new strategies to reinvigorate the immune system and to promote healthy aging”, says Mittelbrunn. “The Centro de Biología Molecular Severo Ochoa offers the ideal environment for our work. Not only do we have state-of-the-art core facilities available here, but I can also exchange ideas with many renowned researchers working on immunity, metabolism and ageing.”

Demostrada la existencia de células madre en el cerebro que permiten la generación de neuronas durante toda la vida
21/10
El equipo de la bióloga María Llorens-Martín en el Centro de Biología Molecular Severo Ochoa (CSIC-UAM) había abierto un campo enorme en el estudio del cerebro cuando, hace año y medio, descubrió neuronas inmaduras en el hipocampo de adultos. La investigadora relata que ese hallazgo “sugeriría la existencia de un proceso de neurogénesis, que esas neuronas nacían durante la vida adulta”. El trabajo continuó para descartar que esas células fundamentales para recibir, procesar y transmitir información se hubieran generado al nacer y quedado en estado de inmadurez, como defendían muchos científicos. Ahora, la investigadora y su equipo han demostrado de forma definitiva, tras el estudio de 48 cerebros adultos (15 de ellos cognitivamente sanos), la existencia de células madre e hijas, que se dividen muy rápidamente (proliferativas), maduran y generan nuevas neuronas. Y las deficiencias en este proceso no son la causa de enfermedades neurodegenerativas, sino al revés: son estas dolencias las que limitan la capacidad de seguir creando neuronas. El estudio lo publica este jueves la revista Science.

03/10
El investigador vasco Jon Gil-Ranedo, junto con Carlos Gallego-García, y José María Almendral, del Centro de Biología Molecular Severo Ochoa (CSIC-UAM), forman un grupo de investigación liderado por José María Almendral catedrático de la UAM, que ha demostrado el potencial terapéutico que tiene un Parvovirus de ratón para infectar y destruir células madre de glioblastoma humano. El trabajo, llevado a cabo íntegramente en este centro de investigación español, tiene un gran interés biomédico en cuanto se ha desarrollado con células madre obtenidas de pacientes de glioblastoma, el tumor cerebral mas agresivo, esencialmente incurable por la medicina actual. La utilidad de este tratamiento se ha demostrado en modelos de ratón implantados en el cerebro con glioblastoma humano.

Sara Barrero es una soriana que podría llegar a hacer historia en el mundo de la bioquímica. De momento, después de acabar la carrera, ha realizado las prácticas en un laboratorio del CSIC. El Centro de Biología Molecular Severo Ochoa acogió a Barrero para realizar sus prácticas y poder elaborar el Trabajo de Fin de Grado, algo que le ha servido para colaborar en un estudio que podría llegar a ser determinante, ya que trabajan in vitro para generar anticuerpos de muy alta afinidad.
La inhibición de dos proteínas activadas por el óxido nítrico revierte los aneurismas de aorta del síndrome de Marfan
11/05
Investigadores del Centro Nacional de Investigaciones Cardiovasculares (CNIC) y del Centro de Biología Molecular Severo Ochoa (CSIC-UAM) han descubierto que la ruta del óxido nítrico (NO) está sobre activada en la arteria aorta tanto de ratones como de pacientes con Síndrome de Marfan, y que dicha ruta es responsable de los aneurismas aórticos característicos de este síndrome.
Experta avanza que pronto habrá medicamentos que actúan sobre el ARN para diferentes tipos de enfermedades
08/04La investigadora de la U746 CIBERER que lidera Belén Pérez en el Centro de Biología Molecular Severo Ochoa (UAM-CSIC), Lourdes Ruiz, ha avanzado que pronto habrá medicamentos de este tipo diseñados tanto para uno solo o muy pocos pacientes (terapias personalizadas) como dirigidos a tratar enfermedades muy comunes. La experta es miembro de un equipo europeo con representantes de 14 países ha publicado un artículo que resume los avances y retos de los medicamentos que actúan sobre el ARN y prevé una aceleración de su desarrollo.
