Characterization of RNA in exosomes secreted by human breast cancer cell lines using next-generation sequencing [PDF]

open access: yesPeerJ, 2013
Exosomes are nanosized (30–100 nm) membrane vesicles secreted by most cell types. Exosomes have been found to contain various RNA species including miRNA, mRNA and long non-protein coding RNAs. A number of cancer cells produce elevated levels of exosomes.

Quantifying Gene Expression [PDF]

open access: yesCurrent Issues in Molecular Biology, 2002
Identifying those genes that are expressed and at what levels is an essential part of almost any biological inquiry at the cellular level. Techniques such as Northern blot have been in existence for decades to perform this task, but advances in molecular biology and bioinstrumentation have led to the development of a variety of new techniques with a ...

Identification of common oncogenic and early developmental pathways in the ovarian carcinomas controlling by distinct prognostically significant microRNA subsets

open access: yesBMC Genomics, 2017
Background High-grade serous ovarian carcinoma (HG-SOC) is the dominant tumor histologic type in epithelial ovarian cancers, exhibiting highly aberrant microRNA expression profiles and diverse pathways that collectively determine the disease ...

Identifying expressed genes [PDF]

open access: yesProceedings of the National Academy of Sciences, 2000
The study of expressed genes has had a great impact on biological research (1). Expressed genes are the basic functional units of genomic DNA. Because these regions cannot be identified from genomic sequence information per se, the gene's products, messenger RNAs or proteins, must be isolated from cells, directly sequenced, and identified.

Positive selection underlies Faster-Z evolution of gene expression in birds. [PDF]

open access: yes, 2015
The elevated rate of evolution for genes on sex chromosomes compared to autosomes (Fast-X or Fast-Z evolution) can result either from positive selection in the heterogametic sex, or from non-adaptive consequences of reduced relative effective population ...

Repeated observation of breast tumor subtypes in independent gene expression data sets

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2003
Characteristic patterns of gene expression measured by DNA microarrays have been used to classify tumors into clinically relevant subgroups. In this study, we have refined the previously defined subtypes of breast tumors that could be distinguished by ...

SWI/SNF catalytic subunits’ switch drives resistance to EZH2 inhibitors in ARID1A-mutated cells

open access: yesNature Communications, 2018
The mechanism of resistance to EZH2 inhibitors in cancers with inactivating SWI/SNF mutations is unknown. Here, the authors demonstrate that the switch of the SWI/SNF catalytic subunits from SMARCA4 to SMARCA2 drives resistance to EZH2 inhibitors in ...

A gene-expression signature as a predictor of survival in breast cancer.

open access: yesNew England Journal of Medicine, 2002
BACKGROUND A more accurate means of prognostication in breast cancer will improve the selection of patients for adjuvant systemic therapy. METHODS Using microarray analysis to evaluate our previously established 70-gene prognosis profile, we classified

Inhibiting stromal Class I HDACs curbs pancreatic cancer progression

open access: yesNature Communications, 2023
Oncogenic lesions in pancreatic ductal adenocarcinoma (PDAC) hijack the epigenetic machinery in stromal components to establish a desmoplastic and therapeutic resistant tumor microenvironment (TME).

Origins of Binary Gene Expression in Post-transcriptional Regulation by MicroRNAs

open access: yes, 2012
MicroRNA-mediated regulation of gene expression is characterised by some distinctive features that set it apart from unregulated and transcription factor-regulated gene expression. Recently, a mathematical model has been proposed to describe the dynamics
