Mutations in the p53 gene have been associated with human tumors including osteosarcomas. This study shows that the over expression of the gene encoding wild-type p53 blocks the growth of osteosarcoma cells. The growth arrest was determined to be due to an inability of the transfected cells to progress to S phase. This suggests that the told of p53 gene as an antioncogene may be in controlling the cell cycle in a fashion analogous to the check point control genes in Saccharomyces cerevisiae. Immunofluorescence and Southern blots were used.

Disruption of both copies of the Foxp2 gene caused severe motor impairment, premature death, and an absence of ultrasonic vocalizations that are elicited when pups are removed from their mothers. Figure 1b shows a southern blot analysis showing the alteration of the mutant foxp2 allele.

Figure 1 A shows DNA damage-induced apoptosis of E1A-expressing MEFs. MEFs were infected with control (pBabe) or E1A-expressing retrovirus (pBabe-E1A), and were treated with adriamycin (0.25 μg/mL) for 24 h. Wild-type (WT) and Noxa-/- MEFs (left), as well as Noxa-/- and Noxa-/-/Bax-/- MEFs (right), were each prepared from the same litter. Results are representative of three independent experiments.

Figure 2 A shows the sub fragments of myosin chains that helps in movement. The recent crystal structure of myosin subfragment-1 suggests the presence of two distinct domains: a catalytic or motor domain, from which extends a long, 8.5-nm alpha-helix that is stabilized by the regulatory and essential light chains.
