Anaplastic thyroid cancer cells reduce CD71 levels to increase iron overload tolerance.

BackgroundFollicular thyroid cancer (FTC) is a prevalent form of differentiated thyroid cancer, whereas anaplastic thyroid cancer (ATC) represents a rare, fast-growing, undifferentiated, and highly aggressive tumor, posing significant challenges for eradication. Ferroptosis, an iron-dependent cell death mechanism driven by the excessive production of reactive oxygen species and subsequent lipid peroxidation, emerges as a promising therapeutic strategy for cancer. It has been observed that many cancer cells exhibit sensitivity to ferroptosis, while some other histotypes appear to be resistant,

Strategies to Improve Sensitivity to Radiotherapy in Pediatric Solid Tumors.

The primary goal in the treatment of pediatric malignancies is to maintain effective cancer control while minimizing toxicities and late effects. Radiotherapy is a component of standard therapy against many pediatric cancers, but tumor cell DNA damage repair mechanisms and the hypoxic tumor microenvironment may limit the effectiveness of this modality. Additionally, irradiated cancer cells often acquire resistance to radiotherapy that permits cancer cell survival or stimulates tumor regrowth after treatment, further limiting the efficacy of radiotherapy. Various preclinical studies have invest

Molecular mechanisms of the preventable causes of cancer in the United States.

Annually, there are 1.6 million new cases of cancer and nearly 600,000 cancer deaths in the United States alone. The public health burden associated with these numbers has motivated enormous research efforts into understanding the root causes of cancer. These efforts have led to the recognition that between 40% and 45% of cancers are associated with preventable risk factors and, importantly, have identified specific molecular mechanisms by which these exposures modify human physiology to induce or promote cancer. The increasingly refined knowledge of these mechanisms, which we summarize here,

Herpes Simplex Virus and Varicella Zoster Virus Infections in Cancer Patients.

Herpes simplex virus (HSV) and varicella zoster virus (VZV) are alpha herpesviruses that establish life-long latent infection in neuronal ganglia after primary infection. Periodic reactivation of these viruses results in recurrent infections that can have significant impact on patients' quality of life. HSV commonly causes oral and genital mucocutaneous infections whereas VZV is responsible for varicella/chickenpox and herpes zoster/shingles, but cancer patients are at particularly higher risk of complications including disseminated and visceral infections due to impaired cell-mediated immunit
