The vertebrate genome contains a predicted 50 000-100 000 genes, many of unknown function. The recent development of morpholino-based gene knock-down technology in zebrafish has opened the door to the genome-wide assignment of function based on sequence in a model vertebrate. This review describes technical aspects of morpholino use for functional genomics applications, including the potential ...

Abstract Synthetic lethality — a genetic interaction that results in cell death when two deficiencies co-occur but not either deficiency occurs alone can be co-opted for cancer therapeutics. A pair of paralog genes is among the most straightforward synthetic lethal by virtue their redundant functions. Here we demonstrate paralog-based targeting Vaccinia-Related Kinase 1 (VRK1) 2 (VRK2)-methylat...

Numerous genes involved in calcification, algal endosymbiosis, and the stress response have been identified corals by large-scale gene expression analysis, but functional analysis of those is lacking. There are few experimental examples manipulation corals, such as knockdown RNA interference (RNAi). The purpose this study to establish an RNAi method for coral juveniles. As a first trial, encodi...

When inferring networks from high-throughput genomic data, one of the main challenges is the subsequent validation of these networks. In the best case scenario, the true network is partially known from previous research results published in structured databases or research articles. Traditionally, inferred networks are validated against these known interactions. Whenever the recovery rate is ga...

Promoter methylation is one of the main epigenetic mechanisms that lead to the inactivation of tumor suppressor genes during carcinogenesis. Due to the reversible nature of DNA methylation, many studies have been performed to correct theses epigenetic defects by inhibiting DNA methyltransferases (DNMTs). In this case novel therapeutics especially siRNA oligonucleotides have been used to specifi...

Highly expressed high mobility group box-1 protein (HMGB1) promotes tumor metastasis. Whether HMGB1 participates in breast cancer cell activation of fibroblasts is unknown. The culture medium 6 lines with different migration potential, and overexpression or knockdown was used to induce fibroblast activation, collagen α-SMA expression were measured. We evaluated the potential MDA-MB-231 cells tr...

Cancer metastasis is largely incurable and accounts for 90% of breast cancer deaths, especially the aggressive basal-like or triple negative (TNBC). Combining patient database analyses functional studies, we examined association integrin family members with clinical outcomes as well their connection previously identified microRNA regulators metastasis, such miR-206 that inhibits stemness TNBC. ...

AlkB homolog 5 (ALKBH5) has been reported as a key m6A demethylase that is involved in development and diseases; however, the function of ALKBH5 osteogenesis remains unknown. In this study, we report mRNA protein expression were upregulated during osteoblast differentiation knockdown suppressed differentiation, mineralization, osteogenic biomarkers. Conversely, overexpression promoted osteogene...

in this study, several designed creb1-specific shrnas cloned into lentiviral transfer vectors were screened in293t by transient transfection assays. relative creb1 expression was determined by relative qrt-pcr. all of the designed shrnas gave some level of knockdown. one shrna was more effective for knocking down the specific gene among others. the predicted sirnas activities as determined by r...
