The Clinical Role of Hypoxia Inducible Factor (HIF) Inhibition in Renal Cancer: A Focus on Belzutifan.

Systemic therapy for metastatic Renal Cell Carcinoma (mRCC) has dramatical-ly improved in the last years because of the use of immunotherapy with checkpoint inhibi-tor combinations with or without targeted therapies against the Vascular Endothelial Growth Factor Receptors (VEGFR). As a result, patients with mRCC have prolonged sur-vival time, but they ultimately develop resistance and the disease progresses, which high-lights the critical need for novel treatment options. The Hypoxia-inducible Factor (HIF) pathway is central to the pathophysiology of ccRCC and von Hippel-Lindau (VHL) disease.

2024 ASCO genitourinary cancers symposium: a focus on renal cell carcinoma.

In this article, we report the breakthrough acquisitions for renal cell carcinoma (RCC) management presented at the 2024 American Society of Clinical Oncology (ASCO) Genitourinary Cancers Symposium. The results from Keynote 564 showed an impressive overall survival (OS) advantage for pembrolizumab, in patients at higher risk of relapse after surgery and confirmed the benefit in terms of disease-free survival (DFS). Until now, pembrolizumab is the only immune checkpoint inhibitor (ICI) to prove a survival advantage.

Post nephrectomy management of localized renal cell carcinoma. From risk stratification to therapeutic evidence in an evolving clinical scenario.

Standard treatment for localized non-metastatic renal cell carcinoma (RCC) is radical or partial nephrectomy. However, after radical surgery, patients with stage II-III have a substantial risk of relapse (around 35%). To date a unique standardized classification for the risk of disease recurrence still lack.

Targeting hypoxia-inducible factor pathways in sporadic and Von Hippel-Lindau syndrome-related kidney cancers.

Hereditary and sporadic renal cell carcinomas (RCCs) are often associated with Von Hippel-Lindau (VHL)-gene inactivation. Patients with VHL disease have an increased risk of RCC, leading to bilateral nephrectomy and dialysis. In patients with advanced RCC, no standard second-lines are available after progression to immune checkpoint inhibitors (ICIs), and new agents are required to manage progression.

Magnesium Modulates Doxorubicin Activity through Drug Lysosomal Sequestration and Trafficking.

Magnesium is directly involved in the control of cell growth and survival, but its role in cancer biology and therapy is multifaceted; in particular, it is highly controversial whether magnesium levels can affect therapy outcomes. Here we investigated whether magnesium availability can modulate cellular responses to the widely used chemotherapeutic doxorubicin. We used an in vitro model consisting of mammary epithelial HC11 cells and found that high magnesium availability was correlated with diminished sensitivity both in cells chronically adapted to high magnesium concentrations and in acutely magnesium-supplemented cells.

EGF stimulates Mg(2+) influx in mammary epithelial cells.

Magnesium is well established as a fundamental factor that regulates cell proliferation. However, the molecular mechanisms linking mitogenic signals, extracellular magnesium availability and intracellular effectors are still largely unknown. In the present study we sought to determine whether EGF regulates magnesium homeostasis in normal HC11 mammary epithelial cells.

From magnesium to magnesium transporters in cancer: TRPM7, a novel signature in tumour development.

Magnesium availability affects many cellular functions that are critical for tumour growth and spreading, such as proliferation, metabolism and angiogenesis. In vivo, magnesium deficiency, and the resulting inflammation, can trigger both anti- and pro-tumour effects. Recent experimental evidence indicates that altered expression of the transient receptor potential melastatin, type 7 (TRPM7) epithelial magnesium channel is a frequent finding in cancer cells and human tumour tissues, and correlates with cell proliferation and/or migration.
