The Tol2kit: a multisite gateway-based construction kit for Tol2 transposon transgenesis constructs.

TLDR
The Tol2kit greatly facilitates zebrafish transgenesis, simplifies the sharing of clones, and enables large‐scale projects testing the functions of libraries of regulatory or coding sequences.
Abstract
Transgenesis is an important tool for assessing gene function. In zebrafish, transgenesis has suffered from three problems: the labor of building complex expression constructs using conventional subcloning; low transgenesis efficiency, leading to mosaicism in transient transgenics and infrequent germline incorporation; and difficulty in identifying germline integrations unless using a fluorescent marker transgene. The Tol2kit system uses site-specific recombination-based cloning (multisite Gateway technology) to allow quick, modular assembly of [promoter]-[coding sequence]-[3' tag] constructs in a Tol2 transposon backbone. It includes a destination vector with a cmlc2:EGFP (enhanced green fluorescent protein) transgenesis marker and a variety of widely useful entry clones, including hsp70 and beta-actin promoters; cytoplasmic, nuclear, and membrane-localized fluorescent proteins; and internal ribosome entry sequence-driven EGFP cassettes for bicistronic expression. The Tol2kit greatly facilitates zebrafish transgenesis, simplifies the sharing of clones, and enables large-scale projects testing the functions of libraries of regulatory or coding sequences.

BICISTRONIC GENE TRANSFER TOOLS FOR DELIVERY OF miRNAS AND PROTEIN CODING SEQUENCES

TL;DR: Results suggest that this cassette allows expression of miRNAs and proteins simultaneously, which provides the opportunity for joint delivery of specific translational repressors (miRNA) and possibly transcriptional activators (transcription factors) for future gene therapy use.

Zebrafish: an underutilized tool for discovery in host-microbe interactions.

TL;DR: In this paper , the authors argue that the zebrafish model provides fertile ground for a new understanding of host-microbe interactions in a transparent host, and they use the model to study host-pathogen interactions.

Dietary cholesterol and apolipoprotein A-I are trafficked in endosomes and lysosomes in the live zebrafish intestine.

TL;DR: A novel assay to visualize live dietary cholesterol trafficking in the zebrafish intestine by feeding TopFluor-cholesterol, a fluorescent cholesterol analog, in a lipid-rich, chicken egg yolk feed is developed and elucidates a key role for endosomal-lysosomal trafficking of intestinal cholesterol and APOA-I.

Osmolarity-independent electrical cues guide rapid response to injury in zebrafish epidermis

TL;DR: It is found that, in addition to sensing osmolarity, basal skin cells in zebrafish larvae are also sensitive to changes in the particular ionic composition of their surroundings after wounding, specifically the concentration of sodium chloride in the immediate vicinity of the wound.

Improved monomeric red, orange and yellow fluorescent proteins derived from Discosoma sp. red fluorescent protein.

TL;DR: The latest red version matures more completely, is more tolerant of N-terminal fusions and is over tenfold more photostable than mRFP1, and three monomers with distinguishable hues from yellow-orange to red-orange have higher quantum efficiencies.

An Hsp70-like protein in the ER: identity with the 78 kd glucose-regulated protein and immunoglobulin heavy chain binding protein.

TL;DR: A cDNA clone is characterized that encodes a protein related to the 70 kd heat shock protein, but is expressed in normal rat liver, and it is identical with two previously described proteins: GRP78, whose synthesis is induced by glucose starvation, and BiP, which is found bound to immunoglobulin heavy chains in pre-B cells.

GAL4-VP16 is an unusually potent transcriptional activator

TL;DR: It is shown that the hybrid protein (GAL4-VP16) activates transcription unusually efficiently in mammalian cells when bound close to, or at large distances from the gene, and suggested that the activating region of VP16 may be near-maximally potent.

DNA Cloning Using In Vitro Site-Specific Recombination

TL;DR: A method called recombinational cloning is described that uses in vitro site-specific recombination to accomplish the directional cloning of PCR products and the subsequent automatic subcloning of the DNA segment into new vector backbones at high efficiency.
