In the field of geroscience analysis of novel genetic mouse models with either a shortened, or an extended, lifespan provides a unique opportunity to evaluate the synergistic roles of longevity assurance pathways in cancer resistance and regulation of lifespan and to develop novel targets for interventions that both delay aging and prevent carcinogenesis. There is a growing need for robust assays to assess the susceptibility of cancer in these models. The present review focuses on a well-characterized method frequently used in cancer research, which can be adapted to study resilience to genotoxic stress and susceptibility to genotoxic stress-induced carcinogenesis in geroscience research namely, chemical carcinogenesis induced by treatment with 7,12-dimethylbenz(a)anthracene (DMBA). Recent progress in understanding how longer-living mice may achieve resistance to chemical carcinogenesis and how these pathways are modulated by anti-aging interventions is reviewed. Strain-specific differences in sensitivity to DMBA-induced carcinogenesis are also explored and contrasted with mouse lifespan. The clinical relevance of inhibition of DMBA-induced carcinogenesis for the pathogenesis of mammary adenocarcinomas in older human subjects is discussed. Finally, the potential role of insulin-like growth factor-1 (IGF-1) in the regulation of pathways responsible for cellular resilience to DMBA-induced mutagenesis is discussed.}, keywords = {MUTATION; CANCER; TUMOR; CARCINOMA; MUTAGENESIS; DNA Repair; Health span}, year = {2019}, eissn = {2509-2723}, pages = {209-227}, orcid-numbers = {Tarantini, Stefano/0000-0001-5627-1430; Ungvári, Zoltán István/0000-0002-6035-6039} } @article{MTMT:30452362, title = {IGF-1 Deficiency Exacerbates Hypertension-Induced Cerebral Microhemorrhages in Mice, Mimicking the Aging Phenotype}, url = {https://m2.mtmt.hu/api/publication/30452362}, author = {Tarantini, Stefano and Valcarcel-Ares, M.

There is growing evidence that aging promotes insulin-like growth factor 1 (IGF-1) deficiency, which compromises multiple aspects of cerebromicrovascular and brain health. To determine the role of IGF-1 deficiency in the pathogenesis of CMHs, we induced hypertension in mice with liver-specific knockdown of IGF-1 (Igf1(f/f) + TBG-Cre-AAV8) and control mice by angiotensin II plus l-NAME treatment. In IGF-1-deficient mice, the same level of hypertension led to significantly earlier onset and increased incidence and neurological consequences of CMHs, as compared to control mice, as shown by neurological examination, gait analysis, and histological assessment of CMHs in serial brain sections. Previous studies showed that in aging, increased oxidative stress-mediated matrix metalloprotease (MMP) activation importantly contributes to the pathogenesis of CMHs. Thus, it is significant that hypertension-induced cerebrovascular oxidative stress and MMP activation were increased in IGF-1-deficient mice. We found that IGF-1 deficiency impaired hypertension-induced adaptive media hypertrophy and extracellular matrix remodeling, which together with the increased MMP activation likely also contributes to increased fragility of intracerebral arterioles. Collectively, IGF-1 deficiency promotes the pathogenesis of CMHs, mimicking the aging phenotype, which likely contribute to its deleterious effect on cognitive function.

The cellular mechanisms by which aging and hypertension interact to promote cerebrovascular pathologies are not well understood. To test the hypothesis that aging exacerbates high pressure-induced mitochondrial oxidative stress, we exposed isolated segments of the middle cerebral arteries of young ( 3 months) and aged ( 24 months) C57BL/6 mice to 60 or 140 mmHg intraluminal pressure and assessed changes in mitochondrial reactive oxygen species production using a mitochondria-targeted redox-sensitive fluorescent indicator dye ( MitoSox) by confocal microscopy. Perinuclear MitoSox fluorescence was significantly stronger in high pressure-exposed middle cerebral arteries compared with middle cerebral arteries of the same animals exposed to 60 mmHg, indicating that high pressure increases mitochondrial reactive oxygen species production in the smooth muscle cells of cerebral arteries.
