The epidermal growth-factor receptor (EGFR) tyrosine kinase inhibitor erlotinib has been proven to be highly effective in the treatment of nonsmall cell lung cancer (NSCLC) harboring oncogenic EGFR mutations. majority patients, however, will eventually develop resistance and succumb disease. Recent studies have identified secondary mutations (EGFR T790M) amplification N-Methyl-N′-nitro-N-nitroso-guanidine (MNNG) HOS transforming gene (MET) oncogene as two principal mechanisms acquired...
Oncogene-induced senescence is a potent barrier to tumorigenesis that limits cellular expansion following certain oncogenic events. Senescent cells display repressive chromatin configuration thought stably silence proliferation-promoting genes while simultaneously activating an unusual form of immune surveillance involving secretory program referred as the senescence-associated phenotype (SASP). Here, we demonstrate also involves global remodeling enhancer landscape with recruitment reader...
Significance p53 is one of the most intensively studied tumor-suppressor genes. We identified a naturally occurring isoform, generated by an alternative-splicing event, that, although lacking transcriptional activity and canonical tumor suppressor functions, able to reprogram cells toward acquisition metastatic features via cyclophilin D interaction in mitochondria matrix. Interestingly, this isoform expressed on tissue injury tumors characterized increased spread. In some these tumors,...
Clinical definitions of asthma fail to capture the heterogeneity immune dysfunction in severe, treatment-refractory disease. Applying mass cytometry and machine learning bronchoalveolar lavage (BAL) cells, we find that corticosteroid-resistant patients cluster largely into two groups: one enriched interleukin (IL)-4+ innate cells another dominated by interferon (IFN)-γ+ T including tissue-resident memory cells. In contrast, BAL a healthier population are IL-10+ macrophages. To better...
Noncoding RNAs play important roles in various aspects of gene regulation. We have identified 7SK RNA to be enriched nuclear speckles or interchromatin granule clusters (IGCs), a subnuclear domain pre-mRNA processing factors. RNA, association with HEXIM 1 and 2, is involved the inhibition transcriptional elongation by polymerase II. Inhibition occurs via sequestration active P-TEFb kinase complex (CDK 9 Cyclin T1/T2a/b K) that phosphorylating C-terminal Our results demonstrate knock-down...
Asthma is a common disease with profoundly variable natural history and patient morbidity. Heterogeneity has long been appreciated, much work focused on identifying subgroups of patients similar pathobiological underpinnings. Previous studies the Severe Research Program (SARP) cohort linked gene expression changes to specific clinical physiologic characteristics. While invaluable for hypothesis generation, these data include extensive candidate lists that complicate target identification...
Background Clustering key clinical characteristics of participants in the Severe Asthma Research Program (SARP), a large, multicenter prospective observational study patients with asthma and healthy controls, has led to identification novel phenotypes. Purpose To determine whether quantitative CT (qCT) could help distinguish between Materials Methods A retrospective cross-sectional analysis was conducted use qCT images (maximal bronchodilation at total lung capacity [TLC], or inspiration,...
Bulk expression data from heterogeneous cell populations pose a challenge for investigators, as differences in numbers and transcriptional programs may complicate analysis. To improve the performance of bulk RNA sequencing on mixed populations, we created Immune Cell Linkage through Exploratory Matrices (ICLite). The ICLite package R constructs modules correlated genes identifies their relationship to specific lineages populations. This protocol details formatting, optimization run...
