The human lncRNA LINC-PINT inhibits tumor cell invasion through a highly conserved sequence element

open access: yesGenome Biology, 2017
Background It is now obvious that the majority of cellular transcripts do not code for proteins, and a significant subset of them are long non-coding RNAs (lncRNAs).

Frequency-modulated nuclear localization bursts coordinate gene regulation [PDF]

open access: yes, 2008
In yeast, the transcription factor Crz1 is dephosphorylated and translocates into the nucleus in response to extracellular calcium. Here we show, using time-lapse microscopy, that Crz1 exhibits short bursts of nuclear localization (typically lasting 2 ...

Multi-locus CRISPRi targeting with a single truncated guide RNA

open access: yesNature Communications
A critical goal in functional genomics is evaluating which non-coding elements contribute to gene expression, cellular function, and disease. Functional characterization remains a challenge due to the abundance and complexity of candidate elements. Here,

Weighted-Lasso for Structured Network Inference from Time Course Data [PDF]

open access: yes, 2009
We present a weighted-Lasso method to infer the parameters of a first-order vector auto-regressive model that describes time course expression data generated by directed gene-to-gene regulation networks. These networks are assumed to own a prior internal

The Penn State Protein Ladder system for inexpensive protein molecular weight markers

open access: yesScientific Reports, 2021
We have created the Penn State Protein Ladder system to produce protein molecular weight markers easily and inexpensively (less than a penny a lane). The system includes plasmids which express 10, 15, 20, 30, 40, 50, 60, 80 and 100 kD proteins in E. coli.

Intrinsic limits to gene regulation by global crosstalk [PDF]

open access: yes, 2016
Gene regulation relies on the specificity of transcription factor (TF) - DNA interactions. In equilibrium, limited specificity may lead to crosstalk: a regulatory state in which a gene is either incorrectly activated due to noncognate TF-DNA interactions

Distance matters: the impact of gene proximity in bacterial gene regulation

open access: yes, 2013
Following recent discoveries of colocalization of downstream-regulating genes in living cells, the impact of the spatial distance between such genes on the kinetics of gene product formation is increasingly recognized.

The metabolic enzyme AdhE controls the virulence of Escherichia coli O157:H7 [PDF]

open access: yes, 2014
Classical studies have focused on the role that individual regulators play in controlling virulence gene expression. An emerging theme, however, is that bacterial metabolism also plays a key role in this process.

Invasion Precedes Tumor Mass Formation in a Malignant Brain Tumor Model of Genetically Modified Neural Stem Cells

open access: yesNeoplasia: An International Journal for Oncology Research, 2011
Invasiveness, cellular atypia, and proliferation are hallmarks of malignant gliomas. To effectively target each of these characteristics, it is important to understand their sequence during tumorigenesis. However, because most gliomas are diagnosed at an

AGO-bound mature miRNAs are oligouridylated by TUTs and subsequently degraded by DIS3L2

open access: yesNature Communications, 2020
3′ end of microRNAs binds to the PAZ domain of Argonaute (AGO) proteins. Here the authors show that terminal nucleotidyltransferases TUT4/7 and exonuclease DIS3L2 induce tailing and decay of 3’ end exposed-microRNAs in AGO PAZ mutant expressing- or ...
