| At birth, mice homozygous for the targeted allele are viable and normal in size and appearence. Female mice exhibit ovaries that lack corpora lutea and hypoplastic uteri that are unresponsive to estrogen. In males, below normal testis weight is associated with a diminished sperm count (10% of normal). Homozygous females are infertile. The fertility of homozygous males is greatly reduced, but not abolished. | ||

| Mice heterozygous for the Dld (dihydrolipoamide dehydrogenase or E3 component) targeted mutation are viable and fertile. Heterozygous mice exhibit approximately half of wild-type enzymatic activity levels for E3 and all affected mitochondrial multienzyme complexes. Heterozygotes (on a C57BL/6;129P2 genetic background) exhibit increased vulnerability to treatments with MPTP (dopaminergic neurotoxin used to induce Parkinson's disease-like lesions), malonate (inhibitor of cellular respiration used to mimic Huntington's disease features), and 3-NP (mitochondrial toxin used to mimic Huntington's disease features). Homozygous mice exhibit normal development and metabolism during the preimplantation period, explained by the persistence of E3 enzyme from the oocyte. Homozygotes exhibit developmental delays shortly after implantation (7.5 to 8.5 days postcoitum (dpc)) and cease development within the subsequent two days. These Dld mutant mice may be useful to study early murine em

| Homozygous mice are viable and fertile and do not express full length mRNA in heart, kidney, spleen, white adipose tissue, and pancreatic islets. In splenic mitochondria, endogenous protein was undetectable. When grown under high glucose conditions, cultured pancreatic islet cells from homozygous mice have increased insulin secretion and ATP levels compared to wildtype. Homozygous mice have 18% lower blood glucose levels. Whether fasting or fed, homozygotes have approximately 3-fold greater serum insulin due to increased insulin secretion. Similarly, glucose-stimulated insulin secretion is significantly increased. High fat diet-fed mice or palmitate-treated islets maintain pancreatic glucose responsiveness in vivo and in vitro compared to wildtype. Mitochondria isolated from the dopaminergic mesencephalic nigral cells of homozygous mice have increased reactive oxygen species but lesser mitochondria number and increased sensitivity to MPTP, mimicking Parkinson’s dise
