Palbociclib plus letrozole in estrogen receptor-positive advanced/recurrent endometrial cancer: Double-blind placebo-controlled randomized phase II ENGOT-EN3/PALEO trial.

Purpose: The CDK4/6 inhibitor palbociclib inhibits cyclin A, which is overexpressed in endometrial cancer. Combining palbociclib with endocrine therapy improves efficacy in hormone receptor-positive breast cancer. We investigated palbociclib combined with endocrine therapy for estrogen receptor-positive advanced/recurrent endometrial cancer.

Exploring the Associations of Inflammatory and Oxidative Stress Biomarkers with Pancreatic Diseases: An Observational and Mendelian Randomisation Study.

Identifying biomarkers linked to pancreatic ductal adenocarcinoma (PDAC) and chronic pancreatitis (CP) is crucial for early detection, treatment, and prevention. Association analyses of 10 serological biomarkers involved in cell signalling (IFN-γ, IL-6, IL-8, IL-10), oxidative stress (superoxide dismutase (SOD) and glutathione peroxidase (GPx) enzyme activities, total glutathione (GSH), malondialdehyde (MDA) levels), and intestinal permeability proteins (zonulin, I-FABP2) were conducted across PDAC ( = 12), CP ( = 21) and control subjects ( = 23). A Mendelian randomisation (MR) approach was used to assess causality of the identified significant associations in two large genetic cohorts (FinnGen and UK Biobank).

VCN-01 disrupts pancreatic cancer stroma and exerts antitumor effects.

Background: Pancreatic ductal adenocarcinoma (PDAC) is characterized by dense desmoplastic stroma that limits the delivery of anticancer agents. VCN-01 is an oncolytic adenovirus designed to replicate in cancer cells with a dysfunctional RB1 pathway and express hyaluronidase. Here, we evaluated the mechanism of action of VCN-01 in preclinical models and in patients with pancreatic cancer.

KRAS phosphorylation regulates cell polarization and tumorigenic properties in colorectal cancer.

Oncogenic mutations of KRAS are found in the most aggressive human tumors, including colorectal cancer. It has been suggested that oncogenic KRAS phosphorylation at Ser181 modulates its activity and favors cell transformation. Using nonphosphorylatable (S181A), phosphomimetic (S181D), and phospho-/dephosphorylatable (S181) oncogenic KRAS mutants, we analyzed the role of this phosphorylation to the maintenance of tumorigenic properties of colorectal cancer cells.

Oncolytic adenovirus with hyaluronidase activity that evades neutralizing antibodies: VCN-11.

Tumor targeting and intratumoral virus spreading are key features for successful oncolytic virotherapy. VCN-11 is a novel oncolytic adenovirus, genetically modified to express hyaluronidase (PH20) and display an albumin-binding domain (ABD) on the hexon. ABD allows the virus to self-coat with albumin when entering the bloodstream and evade neutralizing antibodies (NAbs).
