Spatially resolved transcriptomics has enabled the study of expression genes within tissues while retaining their spatial identity. Most technologies generate a matched histopathological image as part standard pipeline, providing morphological information that can complement data. Here we present CellPie , fast, unsupervised factor discovery method, based on joint non-negative matrix factorisation RNA transcripts and histological features. employs accelerated hierarchical least squares method to significantly reduce computational time, enabling efficient application high-dimensional datasets.

Most patients with metastatic prostate cancer eventually develop resistance to primary androgen deprivation therapy. To identify predictive biomarker for Abiraterone acetate/prednisone resistance, we screened alternative splice variants between responders and non-responders from the PROMOTE clinical study pinned down most significant variant, CENPK–delta8. Through preclinical patient-derived mouse xenograft (PDX) 3D organoids obtained non-responders, as well in vitro models, aberrant CENPK–delta8 expression was determined link drug via enhanced migration proliferation. The FLNA FLOT1 were observed specifically bind CENK–delta8 rather than wild-type CENPK, underscoring role of cytoskeleton organization cell migration. Our study, leveraging data TCGA, TCGA SpliceReq databases, highlights important function response their potential be prognostic biomarkers improving individual therapeutic outcomes precision medicine.

Castration-resistant prostate cancer (CRPC) remains a significant therapeutic challenge due to its resistance standard androgen deprivation therapy (ADT). The emergence of receptor splice variant 7 (AR-V7) has been implicated in CRPC progression, contributing treatment resistance. Current treatments, including first-generation chemotherapy, blockers, radiation therapy, immune and PARP inhibitors, often come with substantial side effects limited efficacy. Natural compounds, particularly those derived from herbal medicine, have garnered increasing interest as adjunctive agents against CRPC. This review explores the role AR-V7 highlights promising benefits natural compounds complementary treatments conventional drugs reducing overcoming We delve into mechanisms action underlying anti-CRPC showcasing their potential enhance outcomes while mitigating associated therapies. exploration offers avenues for developing novel strategies that reduce adverse These provide safer, more effective approach managing CRPC, representing advancement improving patient care.

Abstract RNA binding proteins (RBPs) are essential components of the transcriptomic regulome. Identifying RBP regulome in cancer cells is crucial to discovering and understanding carcinogenesis mechanisms providing new therapeutic targets. Here, we aimed reveal liver upon specific perturbations. To this end, applied a consensus Gene Regulatory Network (GRN) approach using knockdown data for cell line HepG2. By incorporating multiple GRNs from diverse inference methods, constructed highly precise GRN. validate our results, comprehensively evaluated GRN, focusing on characterizing most relevant aspects This included utilizing eCLIP-seq RAPseq verify interactions sites. In addition, performed an enrichment analysis network modules drug repurposing based inferred Taken together, findings demonstrate critical roles regulatory that can be employed improve treatment strategies.

Prostate cancer (PCa) is the most prevalent among men globally. In addition to environmental risk factors, genetic factors play a crucial role in its development and progression, highlighting regulation of key genes as an essential aspect. The androgen receptor gene (AR) plays pivotal this disease, so post-transcriptional must be meticulously coordinated. review, we explore microRNAs (miRNAs) AR PCa, field not yet fully investigated. We note that AR, due extensive 3′UTR region, targeted by numerous miRNAs, can occur at different levels: directly, indirectly, through mutual regulation, thus amplifying influence these molecules on regulation.

Prostate cancer (PCa) is the second most common among men worldwide. The main screening tool remains prostate-specific antigen (PSA), which shows significant limitations, including poor sensitivity/specificity. Therefore, establishing accurate non-invasive diagnostic biomarkers an unmet clinical need in PCa. In this context, splicing process dysregulation represents a PCa hallmark. Here, plasma SRRM1, SNRNP200, and SRSF3 levels, previously identified to play pathophysiological role PCa, were determined control individuals (
