The CRISPR-Cas system is an adaptive immune system found in bacteria which helps protect against the invasion of other microorganisms. This system induces double stranded breaks at precise genomic loci (1) in which repairs are initiated and insertions of a target are completed in the process. This mechanism can be used in eukaryotic cells in combination with sgRNAs (1) as a tool for genome editing. By using this CRISPR-Cas system, in addition to the “safe harbor locus,” ROSAβ26, the incorporation of a target gene into a site that is not susceptible to gene silencing effects can be achieved through few …

The Wnt signaling pathway has been previously shown to play a major role in regulating bone metabolism and it is emerging as a target for the therapeutic intervention of bone thinning disorders such as osteoporosis. Several Wnt proteins have been shown to be expressed in bone and mutations in Wnt pathway members such as Wnt co-receptor Lrp5 and Wnt inhibitor Sost have been shown to be associated with low or high bone mass disorders, however, very little is known about specific roles played by different Wnt ligands in bone development, repair and remodeling. To identify downstream targets of Wnt signaling …

Mammalian cells are known to express genes that are associated with repairing damaged DNA. The transcript CDKN1A is one of several cell cycle regulator genes expressed in response to cell damage by ionizing radiation (IR). In this study, male and female lymphocytes; previously exposed ex vivo to IR, were used to demonstrate linear gene expression responses that may vary between genders. We used qRT-PCR to generate response curves for CDKN1A. No differences were identified for the endogenous control gene GAPDH. CDKN1A expression demonstrated average fold changes well above three fold for three of the four healthy patient donors at 24 …
