Sirt3 knockout: Sirt3 is a mitochondrial-localized tumor suppressor that maintains mitochondrial integrity and metabolism during stress.

Generation of floxed Sirtuin 6 for the construction of conditional knockout mice.

The Sirtuins (Sirt1-7), a family of seven proteins related to yeast Sir2, are histone deacetylases that regulate many critical biological processes including genomic stability, adaptation to calorie restriction and aging. Mice with a targeted disruption of Sirt6 had very low levels of blood glucose (and paradoxically, low insulin levels) and died shortly after weaning. Hypoglycemia, attributed to increased sensitivity to insulin, was the major cause for lethality.

Sirt1 knockout: Sirt1, a protein deacetylase, is a tumor suppressor that promotes genome stability and regulates proteins involved in energy metabolism.

Generation of floxed Sirtuin 1 Exon5-Exon6 for the construction of conditional knockout mice.

FGFR2 knockout is an embryonic lethal mutation and blocks limb bud initiation.

FGFR3 knockout. Complete knockout of the FGFR3 gene, the gene in which missense mutants cause short statue achondroplasia, fails to restrain cartilage growth at the bone growth plate, allowing bones to elongate excessively but fail to ossify.

Tetracycline-responsive transcriptional activator driven by the liver-specific mouse major urinary protein promoter (MUP-tTA).

Tetracycline-responsive transcriptional activator driven by the liver-specific mouse albumin promoter (Alb-tTA).

The National Institutes of Health announces the generation of a construct by ligating 2.5kb human podocin promoter sequence to gene encoding reverse tetracycline-controlled transcriptional activator which enables tetracycline-inducible podocyte specific gene of interest expression with another construct consisting of tetracycline responsive element, minimal CMV promoter and gene of interest.

HSPA2 is a member of the HSP70 family of heat-shock proteins that serve as molecular chaperones. Researchers discovered that HSPA2 protein is expressed in spermatogenesis during the meiotic phase. Spermatogenic cells lacking the HSPA2 protein arrest in mid-meiosis and undergo apoptosis. HSPA2 is present in the synaptonemal complex of wild-type mice and the chromosomes fail to separate in HSPA2-deficient mice (previously known as Hsp70-2-/- mice), suggesting that HSPA2 is required for the chromosomal events of meiosis such as synapsis, crossing over, or recombination.
