● Use of online tools to identify nuclear localization signals in target proteins.

● Use of the PIXImus system (x-ray densitometry) to determine the lengths of mouse tibia.

● Sectioning and histological (H&E, Masson Trichrome) staining of mouse hearts.

● Measurement of nuclear size, cell size, sarcomere length, and collagen area using ImageJ.

● Analysis of promoter regions of genes and miRNA’s found to be up- or down-regulated in the presence of enhanced levels of SRF for the CArG box motif.

● In-silico analysis of 10Kbp promoter regions and first and second introns for interactions of locations and orientations of binding sites for SRF, ETS, ATF, and NFAT with regard to their combinatorial effects on gene expression.
