Evolutionary studies necessary to dissect diverse biological processes have been limited by the lack of reverse genetic approaches in most organisms with sequenced genomes. We established a broadly applicable strategy using zinc finger nucleases (ZFNs) and transcription activator-like effector nucleases (TALENs) for targeted disruption of endogenous genes and cis-acting regulatory elements in diverged nematode species.

Flax is an important crop used for oil and fiber production. Although genetic engineering has been possible in flax, it is not commonly used to produce cultivars. However, the use of genome editing technology, which can produce site-specific mutations without introducing foreign genes, may be a valuable tool for creating elite cultivars that can be easily cultivated.

The occurrence and progression of breast cancer (BCa) are complex processes involving multiple factors and multiple steps. The tumor microenvironment (TME) plays an important role in this process, but the functions of immune components and stromal components in the TME require further elucidation. In this study, we obtained the RNA-seq data of 1086 patients from The Cancer Genome Atlas (TCGA) database.

Human immunodeficiency virus (HIV) is an exemplar virus, still the most studied and best understood and a model for mechanisms of viral replication, immune evasion and pathogenesis. In this review, we consider the earliest stages of HIV infection from transport of the virion contents through the cytoplasm to integration of the viral genome into host chromatin. We present a holistic model for the virus-host interaction during this pivotal stage of infection.

Cellular senescence is a complex biological response to sublethal damage. The RNA-binding protein HNRNPK was previously found to decrease prominently during senescence in human diploid fibroblasts. Here, analysis of the mechanisms leading to reduced HNRNPK abundance revealed that in cells undergoing senescence, mRNA levels declined transcriptionally and full-length HNRNPK protein was progressively lost, while the abundance of a truncated HNRNPK increased.

The leukotriene B4 receptor 2 (BLT2) is a G-protein coupled receptor, which is endogenously activated by 12()-hydroxyheptadeca-5Z,8E,10E-trienoic acid (12-HHT). BLT2 is gaining attention as a potential therapeutic target involved in various pathologies including diabetic wound healing, ophthalmic diseases, and colitis. However, validation of BLT2 as drug target requires chemical probes and pharmacological tools which will allow for application in vivo.
