MetabolomicsDistinct metabolic profiles in lung adenocarcinomas presenting as solid or ground-glass opacities

Metabolomic profiling provides real-time insights into tissue physiology and upstream molecular events. Despite its potential in cancer research, large-scale integrative studies in lung adenocarcinoma (LUAD) remain scarce. We analyzed 262 tissue samples from 165 LUAD patients using metabolomic, t...

MetabolomicsActivated ATF6α is a hepatic tumor driver restricting immunosurveillance

Hepatocellular carcinoma (HCC) is the fastest growing cause of cancer-related mortality with limited therapies. While endoplasmic reticulum (ER)-stress and the unfolded protein response (UPR) are implicated in HCC, the involvement of the UPR-transducer activating transcription factor 6 alpha (ATF...

MetabolomicsThe Metabolic Fate of Oxaliplatin in the Biological Milieu Investigated During In Vivo Lung Perfusion Using a Unique Miniaturized Sampling Approach Based on Solid-Phase Microextraction Coupled with Liquid Chromatography-Mass Spectrometry

Adjuvant chemotherapy after pulmonary metastasectomy for colorectal cancer may reduce recurrence and improve survival rates; however, the benefits of this treatment are limited by the significant side effects that accompany it. The development of a novel in vivo lung perf...

TranscriptomicsMicroRNA sequencing and Novel HPV miRNA discovery in HPV cell lines and human tissue samples
Human papillomaviruses (HPV) preferentially infect keratinocytes of mucous membranes or skin and cause numerous benign and malignant lesions at different anatomical locations. A number of DNA viruses encode their own miRNAs as well. To date, no studies have been able to validate viral miRNAs in papi...

TranscriptomicsTranscription profiling of human solid cancers reveals a precisely regulated gene expression cassette potently modulates metastasis and survival
Successful carcinogenesis involves the integration of both pro- and anti-oncogenic pathways. We postulated that genes critical for balancing these opposing pathways are likely to be precisely controlled in tumors, since even subtle alterations in their activity might cause substantial alterations in...

TranscriptomicsComparison of primary neuroblastoma tumors and derivative early-passage cell lines using genome-wide SNP array analysis
Stromal contamination is one of the major confounding factors in the analysis of primary solid tumor samples by single nucleotide polymorphism (SNP) arrays. As we propose to employ genome-wide SNP microarray analysis as a diagnostic platform for neuroblastoma, the sensitivity, specificity, and accur...

TranscriptomicsBreast Cancer Initiating Cells RNA-seq
We previously reported the isolation and in vitro propagation of highly tumorigenic mammospheres (MCFS) isolated from MCF7 breast cancer cell line. In this study we obtained gene expression profiles of MCFS and parental MCF7 cell lines using SOLiD RNA-sequencing after linear isothermal DNA amplifica...

TranscriptomicsTranscriptional analysis of an E2F gene signature as a biomarker of activity of the cyclin-dependent kinase inhibitor PHA-793887 in tumor and skin biopsies from a phase I clinical study
Microarray analysis of transcriptional changes in biopsies of solid tumors from patients treated in a Phase I study with the Cdk inhibitor PHA-793887. 7 patient biopsies pre- and post-treatment in dye swap. Tumors are of different origins, and are described in the accompanying manuscript.

TranscriptomicsDifferential effects of antofine N-oxide on solid tumor and leukemia cells
We have studied the anti-cancer activities of antofine N-oxide isolated and purified from the medicinal plant Cynanchum vincetoxicum. The compound displays a strong cytotoxic effect on several solid tumor cell lines (glioblastoma, breast carcinoma and lung carcinoma) and on T-cell leukemia. It induc...

MetabolomicsTargeting secreted MDK-mediated tryptophan/kynurenine metabolism enhances DLL3 CAR T therapy for SCLC

Small cell lung cancer (SCLC) exhibits profound immunometabolic suppression that impairs antigen presentation and constrains immunotherapy efficacy. Through integrated multi-omics analyses of primary human SCLC tumors, we identified midkine (MDK) as a dominant tumor-secreted driver of immune evas...
