Abstract
Protection of asiatic acid (AA) in mice brain against D-galactose (DG) induced aging was examined. AA at 5, 10 or 20 mg kg(-1) per day was supplied to DG treated mice for 8 weeks. AA intake at 10 or 20 mg kg(-1) per day increased its deposit in brain. DG treatment increased Bax, cleaved caspase-3 protein expression and decreased Bcl-2 expression. AA intake at 10 and 20 mg kg(-1) per day declined Bax, cleaved caspase-3 expression, and retained Bcl-2 expression. DG treatment decreased brain glutathione content and glutathione peroxidase activity; increased brain reactive oxygen species and protein carbonyl levels, and enhanced NAPDH oxidase expression. AA intake at test doses reversed these changes. DG treatment up-regulated the expression of advanced glycation end product (AGE), carboxymethyllysine, receptor of AGE (RAGE), mitogen-activated protein kinases and CD11b as well as increasing the interleukin (IL)-6 and tumor necrosis factor (TNF)-alpha release in the brain. AA intake at 5, 10 and 20 mg kg(-1) per day lowered AGE and carboxymethyllysine expression, and at 10 and 20 mg kg(-1) per day reduced RAGE production. AA intake dose-dependently suppressed p-p38 expression and lowered IL-6 and TNF-alpha levels, and at 10 and 20 mg kg(-1) per day down-regulated p-JNK and CD11b expression. DG treatment declined brain-derived neurotropic factor (BDNF) expression and raised glial fibrillary acidic protein (GFAP) expression. AA intake at 20 mg kg(-1) per day retained BDNF expression and at 10 and 20 mg kg(-1) per day reduced GFAP expression. These findings indicated that the supplement of asiatic acid might be beneficial to the prevention or alleviation of brain aging.

Comparative study of perception and processing of socially or sexually significant odor information in male rats with normal or accelerated senescence using fMRI. Behav Brain Res 2015; 294:89-94.

Abstract
Olfaction plays an important role in mammals while aging causes olfactory dysfunction. Here the features of olfactory function in aging male rats were studied. We compared brain activity of regions involved in the perception (olfactory bulbs) and processing (cerebral cortex, hippocampus, hypothalamus) of sexually or socially significant odor stimulus with 11.7 T MR-scanner and odor perception using behavioral tests in 5-month old males with normal (Wistar rats) or accelerated senescence (d-galactose-treated Wistar rats (150 mg/kg/day, i.p., 12 weeks) or OXYS rats with hereditary defined accelerated aging). d-galactose-treated Wistar males had altered BOLD-response in the centers processing socially significant odor information and changed patterns of the functional connectivity. We detected no significant changes in the olfactory function of OXYS males probably due to compensatory processes. In saline-treated Wistar rats, the correlation of BOLD-responses to both types of stimuli in the olfactory bulbs and cerebral cortex indicated changes in odor differentiation. Behavioral tests showed no significant differences between groups. However, the time of odor exploration increased in d-galactose-treated males indicating changes in odor recognition. Thus, we first revealed that in animal model of pharmacologically induced aging olfactory dysfunction occurred at the level of the centers processing socially significant odor information while the centers of odor perception (olfactory bulbs) remained unaffected. Alterations observed in Wistar rats chronically treated with saline evidenced the influence of long-term manipulations with experimental animals on olfactory function per se.

Differential expression of inflammasomes in lung cancer cell lines and tissues. Tumour Biol 2015; 36:7501-13.

Abstract
As pivotal elements involved in inflammation, inflammasomes represent a group of multiprotein complexes triggering the maturation of proinflammatory cytokine interleukin (IL)-1β and IL-18. Although the importance of the inflammasomes in inflammatory diseases is well appreciated, a precise characterization of their expressions in lung cancer remains obscure. This study aimed to determine the expressions of inflammasomes in various lung cancer cell lines and tissues to understand their potential roles in lung cancer. Our findings showed that inflammasome components were markedly upregulated in lung cancer and elicited the maturation of IL-1β and IL-18. In addition, enormous variations in subtypes and levels of inflammasomes were detected in lung cancers depending on their histological type and grading, invasion ability, as well as chemoresistance. Generally, AIM2 inflammasome was overexpressed in nonsmall cell lung cancer (NSCLC), while NLRP3 inflammasome was upregulated in lung adenocarcinoma (ADC) and small cell lung cancer (SCLC). The high-metastatic or cisplatin-sensitive NSCLC cells expressed more inflammasome components and products than their counterpart low-metastatic or cisplatin-resistant NSCLC cells, respectively. In resected lung cancer tissues, high-grade ADC expressed more inflammasome components and products than low-grade ADC. Together, these findings suggest that inflammasomes may be crucial biomarkers for lung cancer as well as potential modulators of the biological behaviors of lung cancer. Further, pharmacotherapeutics targeting inflammasomes might be novel adjuvant therapy strategies for lung cancer.

Abstract
Chronic exposure to d-galactose (d-gal) serves as a model for age-related oxidative damage and cognitive dysfunction. However, methods used, including the dose and treatment time of d-gal as well as the gender, age and strain of animals used, vary greatly among published articles. In this study, we investigate the effect of gender, age and treatment time on brain oxidative stress and spatial memory deficits induced by d-gal in mice, respectively. Eight-week-old female mice injected with 100mg/kg d-gal per day, for 6 weeks, did not show spatial memory impairment or high levels of hydroxyl radical, protein carbonyl and malondialdehyde in brain homogenates, although brain reactive oxygen species were increased when compared with saline control mice. In contrast, both 8-week-old male mice and 24-week-old female mice receiving 100mg/kg d-gal for 6 weeks, or 8-week-old female mice receiving 100mg/kg d-gal for 10 weeks showed spatial memory deficits and significant increases in the above oxidative markers, compared with their corresponding controls. These results demonstrate that d-gal-induced brain oxidative stress and spatial memory impairment are dependent upon exposure time of d-gal, plus gender and age of the animals used. The findings can serve as a useful guide for successfully establishing d-gal induced age-related oxidative damage models.

Abstract
One of the important factors in aging is oxidative stress and aging-related disturbances are believed be ameliorated by antioxidants. Diosgenin is a bio-active ingredient of dioscorea that is widely used in Chinese medicine, shows anti-oxidant activity and improves some aging-related deficits in senescent and menopausal animals. We compared alterations in behavior, biochemical parameters (plasma levels of the uric acid, creatinine, calcium, phosphate, total cholesterol, low-density lipoprotein cholesterol and triglycerides, and the plasma activity of aminotransferases AST and ALT), and sperm motility in two models of accelerated senescence (d-galactose-induced (150 mg/kg/day, i.p., 57 days) aging in Wistar rats vs. genetically defined in OXYS rats) and examined the protective effects of diosgenin (10 or 50mg/kg/day, p.o., 57 days). Both models had augmented levels of ALT activity indicating hepatopathology. Compared to d-galactose-treated animals, OXYS rats demonstrated profound biochemical alterations (hypocalcemia, hypophosphatemia, and hypocholesterolemia) and behavioral deficits (impaired object recognition, decreased sexual motivation and locomotor activity, retarded learning) that confirmed the difference in the mechanisms of accelerated senescence in these models. We first showed diminished sperm motility in males of both models of accelerated senescence studied. Chronic diosgenin treatment failed to improve biochemical and behavioral disturbances and had some undesirable side effects on body weight and working memory in OXYS rats. However, diosgenin restored moderately decreased sperm motility in d-galactose-treated Wistar males and might be recommended for treatment of mild age-related reproductive dysfunctions.
