Dear reader, here are the summaries of some of the latest papers from PubMed.

Ferroptosis:

• Source: Ferroptosis and immune microenvironment alterations are key factors in osteosarcoma development, and resveratrol may inhibit OS progression by interacting with specific molecular targets.

• Source: Resveratrol modulates chondrocyte ferroptosis pathways and reduces inflammatory cytokine expression, offering a potential therapeutic strategy for osteoarthritis.

• Source: Resveratrol suppresses OSCC growth through inhibition of the NORAD/IGF2BP2/PDK1 signaling pathway.

• Source: This paper presents a nanoplatform that hijacks ferritin and ferroportin to increase intracellular free iron levels, thereby enhancing the efficacy of ferroptosis therapy in cancers.

• Source: MicroRNAs play crucial roles in regulating ferroptosis across various diseases by modulating key genes involved in iron metabolism, lipid peroxidation, and antioxidant defense, offering potential as diagnostic biomarkers and therapeutic targets.

• Source: Sarcosine enhances ferroptosis in lung adenocarcinoma cells, thereby overcoming chemoresistance.

• Source: Lipid peroxidation and ferroptosis not only kill tumor cells but also create an immunosuppressive environment within the tumor microenvironment, impacting various immune cell functions. This dual role complicates the clinical application of ferroptosis-based therapies and highlights the need for further research to address these immunosuppressive effects.

• Source: Ferroptosis induction shows promise as a therapeutic approach for triple-negative breast cancer due to its ability to target cells resistant to conventional chemotherapy.

• Source: Dysregulation of iron, lipid metabolism, or antioxidant systems can trigger ferroptosis, which plays a key role in the development and progression of kidney diseases.

• Source: Resveratrol mitigates DOX-induced apoptosis and DNA damage in Saos-2 cells, suggesting a protective role against DOX’s cytotoxic effects.

• Source: SM-3, a resveratrol derivative, effectively inhibits mTOR protein activity, leading to reduced cancer cell growth and enhanced sensitivity to therapy in lung cancer cells.

Influenza Vaccination:

• Source: Influenza vaccination provided limited protection against ILI for immunocompromised adults and those with high-risk chronic conditions during the 2017-2018 season, as evidenced by comparing vaccinated individuals to those with no evidence of vaccination.

• Source: Repeated annual influenza vaccinations may reduce future vaccine effectiveness, and explores potential immunological reasons for this decline, aiming to identify ways to improve vaccine efficacy.

• Source: Patients, particularly those who have undergone allogeneic hematopoietic stem cell transplantation, are at a higher risk for influenza virus infections, which can lead to severe complications such as lower respiratory tract infection, especially in older patients and those with chronic graft-versus-host disease.

• Source: A vaccine mandate for nonessential venues in New Orleans was associated with increased vaccination rates and reduced COVID-19 transmission.

• Source: Low vaccine literacy contributes to vaccine hesitancy and low vaccination rates among Black pregnant and postpartum women in the USA, highlighting the need for targeted interventions addressing systemic inequalities in health information access.

• Source: The study found that using PCV21 in vaccine-naive adults with underlying health conditions significantly reduces healthcare costs and improves health outcomes compared to current vaccination practices.

That’s enough for today, see you tomorrow!
