Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

Molecular Oncology, Volume 20, Issue 5, Page 1299-1322, May 2026.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

Visualized Clinical‐Radiomics Model Based on Non‐Contrast Computed Tomography for Predicting Efficacy of Surufatinib in Hepatic Metastases of Neuroendocrine Neoplasms

Cancer Medicine, Volume 15, Issue 5, May 2026.
NCCT radiomics for surufatinib efficacy prediction in HM‐NENs. ABSTRACT Background Hepatic metastatic neuroendocrine neoplasms (HM‐NENs) have few treatment biomarkers and low survival rates. We created a clinical‐radiomics fusion model based on non‐contrast computed tomography (NCCT) to predict Surufatinib efficacy in HM‐NENs.

A Biochemically “Silent” Aortocaval Paraganglioma in a 19‐Year‐Old Female Causing Intraoperative Hypertensive Crisis: A Rare Case Report

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Paragangliomas may appear biochemically silent, yet still behave as functional tumors with severe intraoperative consequences. Normal preoperative catecholamine screening does not exclude the risk of hypertensive crisis during surgery.

Oncogenic driver and therapeutic target: Prolactin signalling axis in retroperitoneal sarcoma

Clinical and Translational Medicine, Volume 16, Issue 5, May 2026.
Retroperitoneal sarcoma cells can secrete prolactin into the bloodstream, inducing hyperprolactinaemia, which subsequently triggers metabolic reprogramming, such as glucose metabolism. SOX4 can function as a transcription factor that facilitates PRL transcription.
