Background: High-grade serous ovarian cancer (HGSOC) remains one of the most challenging gynecological malignancies, with over 70% of ovarian cancer patients ultimately experiencing disease progression. The current prognostic tools for progression-free survival (PFS) in HGSOC patients have limitations. This study aims to develop an explainable machine learning (ML) model for predicting PFS in HGSOC patients.

Background: Preoperative neoadjuvant chemoradiotherapy (nCRT) is considered to be the standard treatment strategy for locally advanced rectal cancer (LARC); however, the risk of adverse events and postoperative recurrence remains significant. This study aimed to evaluate the non-inferiority of neoadjuvant chemotherapy (nCT) compared with nCRT in patients with LARC and to assess the possibility of eliminating radiotherapy on the basis of guaranteed efficacy.

Materials And Methods: We searched the PubMed, Embase, and Cochrane Library databases to identify randomized controlled trials (RCTs) comparing the efficacy of nCRT and nCT for LARC.

Glia contribute to the neuropathology of Parkinson disease (PD), but how they react opposingly to be beneficial or detrimental under pathological conditions, like promoting or eliminating SNCA/α-syn (synuclein alpha) inclusions, remains elusive. Here we present evidence that aux (auxilin), the homolog of the PD risk factor GAK (cyclin G associated kinase), regulates the lysosomal degradation of SNCA/α-syn in glia. Lack of glial GAK/aux increases the lysosome number and size, regulates lysosomal acidification and hydrolase activity, and ultimately blocks the degradation of substrates including SNCA/α-syn.

The naturalistic paradigm and analytical methods present new approaches that are particularly suitable for research concentrating on narrative reading development. We analyzed fMRI data from 44 adults and 42 children engaged in story reading using time-locked inter-subject correlation (ISC), inter-subject representation similarity analysis (IS-RSA), and inter-subject functional correlation (ISFC). The ISC results indicated that for both children and adults, narrative reading recruited not only traditional reading areas but also regions that are sensitive to long-time-scale information, such as the medial prefrontal cortex and hippocampus, which increased involvement from children to adults.

Translational Medicine Center, Baotou Central Hospital (Baotou Clinical Medical College, Affiliated to Inner Mongolia Medical University), Baotou, China.

Wound healing is a dynamic process involving multiple cell types and signaling pathways. Dermal sheath cells (DSCs), residing surrounding hair follicles, play a critical role in tissue repair, yet their regulatory mechanisms remain unclear. This study used single-cell proteomics with the mouse model to explore DSC function across different healing stages.

Introduction: Muscarinic 1 acetylcholine receptor (M1AChR) is a member of the Gprotein- coupled receptor superfamily, with the dysfunction being linked to the onset of Alzheimer's Disease (AD).

Aims: Retromer complex with Vacuolar Protein Sorting-35 (VPS35) as the core plays an important role in the transport of biological proteins and has been confirmed to be closely related to the pathogenesis of AD. This study was designed to determine whether VPS35 could affect the trafficking mechanism of M1AChRs.

Anlotinib, a tyrosine kinase inhibitor, has shown encouraging antitumor activity in platinum-resistant/refractory ovarian cancer. The efficacy of anlotinib as maintenance therapy in advanced ovarian cancer remains unclear. Therefore, we designed this study to evaluate the efficacy and safety of anlotinib maintenance therapy following first-line treatment with paclitaxel and platinum-based chemotherapy in advanced ovarian cancer.

This study aims to investigate the expression of GPER in EC, assess the impact of estrogen on the proliferation and migration of EC via GPER, and examine the potential role of GPER in mediating the NOTCH pathway to influence EC proliferation and migration. The expression of GPER and its correlation with clinicopathological features were investigated using clinical data. Cell proliferation was assessed through MTT and EdU assays, while cell migration ability was evaluated using wound healing and transwell assays.

The Pro-Migratory and Pro-Invasive Roles of Cancer-Associated Fibroblasts Secreted IL-17A in Prostate Cancer.

J Biochem Mol Toxicol

February 2025

Department of Urology and Andrology, The First Affiliated Hospital, Sun Yat-sen University, Guangzhou, China.

Cancer-associated fibroblasts (CAFs) are key stroma cells that play dominant roles in the migration and invasion of several types of cancer through the secretion of inflammatory cytokine IL-17A. This study aims to identify the potential role and regulatory mechanism of CAFs-secreted IL-17A in the migration and invasion of prostate cancer (PC). CAFs and normal fibroblasts (NFs) were obtained from fresh PC and its adjacent normal tissues, respectively.
