Abstract Long non-coding RNAs (lncRNAs) are a growing focus of cancer genomics studies, creating the need for resource lncRNAs with validated roles. Furthermore, it remains debated whether mutated can drive tumorigenesis, and such functions could be conserved during evolution. Here, as part ICGC/TCGA Pan-Cancer Analysis Whole Genomes (PCAWG) Consortium, we introduce Cancer LncRNA Census (CLC), compilation 122 GENCODE causal roles in phenotypes. In contrast to existing databases, CLC requires...

Abstract ENCODE comprises thousands of functional genomics datasets, and the encyclopedia covers hundreds cell types, providing a universal annotation for genome interpretation. However, particular applications, it may be advantageous to use customized annotation. Here, we develop such custom by leveraging advanced assays, as eCLIP, Hi-C, whole-genome STARR-seq on number data-rich types. A key aspect this is comprehensive experimentally derived networks both transcription factors RNA-binding...
Abstract The catalog of cancer driver mutations in protein-coding genes has greatly expanded the past decade. However, non-coding are less well-characterized and only a handful recurrent mutations, most notably TERT promoter have been reported. Here, as part ICGC/TCGA Pan-Cancer Analysis Whole Genomes (PCAWG) Consortium, which aggregated whole genome sequencing data from 2658 across 38 tumor types, we perform multi-faceted pathway network analyses 2583 genomes 27 types compiled by PCAWG...
Multi-region sequencing is used to detect intratumor genetic heterogeneity (ITGH) in tumors. To assess whether genuine ITGH can be distinguished from artifacts, we performed whole-exome (WES) on three anatomically distinct regions of the same tumor with technical replicates estimate noise. Somatic variants were detected different WES pipelines and subsequently validated by high-depth amplicon sequencing. The cancer-only pipeline was unreliable, about 69% identified somatic being false...

Treatment associated in gene levels were compared t-test with Bonferroni correction. count, metagenes Wilcoxon test....
Neural stem cells (NSCs) are critical for brain development and maintenance of neurogenesis. However, the molecular mechanisms that regulate NSC proliferation differentiation remain unclear. Mysm1 is a deubiquitinase essential self-renewal several cells. It unknown whether plays an important role in NSCs. Here, we found was expressed NSCs its expression increased with age mice. Mice knockdown by crossing floxed mice Nestin-Cre exhibited abnormal microcephaly. deletion promoted apoptosis,...
Abstract The discovery of driver mutations is one the key motivations for cancer genome sequencing. Here , as part ICGC/TCGA Pan-Cancer Analysis Whole Genomes (PCAWG) Consortium which aggregated whole sequencing data from 2658 cancers across 38 tumour types, we describe DriverPower, a software package that uses mutational burden and functional impact evidence to identify in coding non-coding sites within genomes. Using total 1373 genomic features derived public sources, DriverPower’s...
Reprogramming of glucose metabolism is a key event in tumorigenesis and progression. Here, we show that active c-Src stimulates glycolysis by phosphorylating (Tyr194) activating PFKFB3, enzyme boosts producing fructose-2,6-bisphosphate PFK1. Increased intermediates replenish non-oxidative pentose phosphate pathway (PPP) serine for biosynthesis cancer cells. PFKFB3 knockout (KO) cells their counterpart reconstituted with PFKFB3-Y194F comparably impaired abilities proliferation, migration,...
A precise predictive biomarker for TNBC response to immunochemotherapy is urgently needed. We previously established a 27-gene IO signature derived from 101-gene model classifying TNBC. Here we report pilot study assess the performance of in predicting pCR preoperative immunochemotherapy. obtained RNA sequencing data primary tumors 55 patients with TNBC, who received neoadjuvant PD-L1 blocker durvalumab. determined power and accuracy immunomodulatory (IM) subtype identified by model,...
Abstract Purpose: We examined gene expression, germline variant, and somatic mutation features associated with pathologic response to neoadjuvant durvalumab plus chemotherapy in basal-like triple-negative breast cancer (bTNBC). Experimental Design: Germline whole-exome DNA RNA sequencing, programmed death ligand 1 (PD-L1) IHC, stromal tumor-infiltrating lymphocyte scoring were performed on 57 patients. validated our results using 162 patients from the GeparNuevo randomized trial. Results:...
Temporal predictive models have the potential to improve decisions in health care, public services, and other domains, yet they often fail effectively support decision-makers. Prior literature shows that many misalignments between model behavior decision-makers' expectations stem from issues of specification, namely how, when, for whom predictions are made. However, specifications tasks highly technical difficult non-data-scientist stakeholders interpret critique. To address this challenge...
Background Research data regarding the correlation between elevated oxidised low-density lipoprotein (oxLDL) cholesterol concentrations and unfavourable clinical outcomes in individuals experiencing minor acute ischaemic cerebrovascular events or transient attack (TIA) with presumed atherosclerotic aetiology are still limited. Methods This investigation incorporated a cohort of 5814 participants derived from Intensive Statin Antiplatelet Therapy for Acute High-Risk Intracranial Extracranial...
We previously reported that p38 MAPK signaling is required for osteoclast differentiation but not function. Here we further investigated the role of in function and mouse bone marrow macrophages (BMM phi), common precursors osteoclasts dendritic cells. Lipopolysaccharide (LPS) activated pathway BMM phi by sequential phosphorylation kinase 3/6, MAPK, activating transcription factor-2. Treatment with SB203580, a inhibitor, suppressed LPS-induced LPS stimulated production IL-1 beta, TNF alpha,...

Two hallmarks of cancer cells are their resistance to apoptosis and ability thrive despite reduced levels vital serum components. c-jun N-terminal kinase (JNK) activation is crucial for triggered by starvation (SS), isocitrate dehydrogenase 1 (IDH1) mutations tumorigenic, in part, because they produce the abnormal metabolite 2-hydroxyglutarate (2-HG). However, it unknown whether 2-HG-induced tumorigenesis partially due JNK inhibition thus defective SS-induced apoptosis. We show here, using...
