Cortisol from exercising suppresses the next cortisol response to a stressor. Exercise before doing something stressful.

Excited that part of my thesis work was published last week in NAR Cancer! Work from our lab and others have shown that cancers with IDH1/2 mutations have a defect in homology-directed repair (HDR), rendering them sensitive to PARP inhibitor treatment.🧵 academic.oup.com/narcancer/a…

As an MD/PhD, I'm probably biased here, but I find these oversimplified generalizations hard to understand. A quick look at any list of influential biomedical scientists (Nobel laureates, leaders across fields, big pharma CSOs, biotech founders) shows that MD/PhDs (or MDs deeply engaged in research) are prominently represented. Many are also excellent clinicians, particularly in highly specialized or rare disease areas, where clinical insight is the often the only driver of scientific discovery. So the claim that MD/PhDs "seldom advance either basic knowledge or clinical practice" doesn’t hold up. And the shift toward administrative or leadership roles later in one’s career isn’t unique to MD/PhDs. Most MD/PhDs I know are among the hardest-working people in either medicine or science. They commit to 15-20 years of training and most often end up earning less than purely clinical peers.
The physician–scientist track (MD/PhD) in academic medical centers has become one of the great illusions of modern science - a path that promises to unite medicine and science but rarely fulfills either goal. Training stretches on for years as one person is expected to learn two professions at once, and in practice, they seldom master either. Many hold a token clinic for a few hours a week while running labs that produce derivative “translational” research — supposedly aimed at improving patient care. In reality, these efforts seldom advance either basic knowledge or clinical practice in a meaningful way. The personal rewards, however, are significant: MD/PhDs are paid far more than PhDs alone, face far less competition for faculty positions, are treated better by upper administration, and are freed from the full clinical responsibilities of practicing physicians. They also enjoy privileged access to administrative roles in medical centers, journals, and professional societies - positions that often pay handsomely. Yet almost no one has seriously examined whether this track delivers genuine scientific or medical value, or if it merely sustains another bureaucratic layer within an already bloated healthcare system. students-residents.aamc.org/…

Excited to see my PhD work out! Here, we find an unexpected epigenetic mechanism that regulates oncogene amplification to promote tyrosine kinase inhibitor resistance in lung adenocarcinoma. Tweetorial below! ⬇️ nature.com/articles/s41594-0…

Hi everybody! I am super excited to share the work done during my PhD published in @nature today! We describe a new mechanism of self- vs. non-self RNA discrimination by showing how N-glycans shield glycoRNAs from stimulating endosomal RNA sensors nature.com/articles/s41586-0…

Yale researchers engineered an antibody, #TMAB3, to carry immune-activating RNA directly to hard-to-treat tumors-shrinking tumors, ⬆️ survival, avoiding healthy tissue. “This lays the foundation for personalized, tumor-targeted RNA therapies,”@Escobar_Lab. yalecancercenter.org/news-ar… @SmilowCancer @ScienceTM

Grateful to be one of the recipients for the Pershing Square Sohn Cancer Prize from @psscra! It will greatly help our work to develop a novel vaccine for pancreatic cancer. Work was led by our post docs @nanamedici and Diana Martinez-Saucedo! @YaleMed @YaleCancer
Replying to @psscra
Dr. Luisa Escobar-Hoyos and the @Escobar_Lab at @YaleMed are developing a novel pancreatic cancer vaccine that leverages the body's existing immunity to bacteria to target and destroy pancreatic tumors. Congrats, Luisa! vimeo.com/1085105016

When achieving milestones, I try to reflect on past experiences that helped me get to where I am now. With this one, and with recent news, I reflect on how programs such as MARC and RISE give underrepresented minorities the resources and platform to pursue careers in STEMM…
I’m extremely excited and fortunate to have been awarded a NRSA F30 Fellowship by the National Cancer Institute! This grant further enhances my integrated research and clinical training as I pursue a career as a physician-scientist. Grateful to my PI, mentors, and support system!

As a former MARC scholar from @uprm, it saddens me to hear that these programs will not continue, but I am hopeful that the scientific community will continue this work, even if unofficially. Efforts like these are crucial to the advancement of science and medicine.
