In the present study developmental changes in the cerebral sulci and volumes of subcortical and archicortical structures of the cerebrum in cynomolgus monkey fetuses were examined with T1-weighted magnetic resonance (MR) images in 3D. On the embryonic day (ED) 90, the lateral ventricle had still an immature vesicular shape in the occipital region of the cerebrum, and it dramatically closed its lumen by ED 100. In that period the calcarine sulcus progressively infolded from the medial surface of the cerebral hemisphere narrowing the lumen of the lateral ventricle in the occipital region. Volume of the lateral ventricle decreased in the period ED 90-100, increasing afterwards in spite of increasing volumes of subcortical and archicortical structures such as the caudate nucleus, putamen, globus pallidus, amygdala and hippocampal formation. During the same time, the volume of the germinal matrix around lateral ventricles decreased to disappear completely by ED 120. These results suggest that the morphological maturation of lateral ventricle is linked to the development of calcarine sulcus in cynomolgus monkey fetuses. The degree of infolding of calcarine sulcus on ED 100 would be useful as a gross anatomical landmark for evaluating the cerebral maturation in cynomolgus monkey fetuses. © 2011 by Polish Neuroscience Society - PTBUN, Nencki Institute of Experimental Biology.

The ontogenetic pattern of gyrification and its relationship with cerebral cortical volume were examined in cynomolgus monkey fetuses. T1-weighted coronal magnetic resonance (MR) images at 7 T were acquired from the fixed cerebra of three male fetuses, each at embryonic days (EDs) 70 to 150, and the gyrification index (GI) of each slice was estimated. The mean GI was low (1.1-1.2) during EDs 70 to 90, and then increased dramatically on ED 100. The developmental profiles of the rostrocaudal GI distribution revealed that cortical convolution was more frequent in the parietooccipital region than in other regions during EDs 100 to 150, forming an adult-like pattern by ED 150. The mean GI was closely correlated with the volume of cortical gray matter (r=0.9877), and also with the volume of white matter/intermediate zone (r=0.8961). These findings suggest that cortical convolution is correlated with either the maturation of cortical gray matter or the development of white matter bundles. The characteristic GI distribution pattern of catarrhines was formed by ED 150 in correlation with the progressive sulcal infolding in the parietooccipital region of the cerebrum. © 2010 IBRO.

A major laboratory company that sells primates was sued by the U.S. Department of Agriculture for violations of the Animal Welfare Act. The action against Shin Nippon Biomedical Laboratories USA, filed last month, follows several years of official complaints filed by the group People for the Ethical Treatment of Animals (PETA). The USDA alleges dozens of monkey deaths “willfully violated the Animal Welfare Act,” according to the administrative lawsuit, dated Sept. 22. “The gravity of the violations alleged in this complaint is great and includes 38 deaths of nonhuman primates and repeated instances in which Respondent failed to provide adequate veterinary care to animals and failed to meet the minimum standards for its facilities,” the agency alleges. SNBL was reached by phone Wednesday, but did not respond to Laboratory Equipment’s request for comment. The alleged mistreatment spans five years, from 2011 to May of this year, according to the papers. Among the accusations included are a shipment of 840 long-tailed macaques from Cambodia to Houston in the fall of 2013. Upon their farther travels to Washington and Texas, 25 of them died or were euthanized due to organ failure caused by dehydrations and hypoglycemia, according to the agency. A whistleblower report in 2011 detailed earlier abuse and neglect of monkeys, according to PETA. The USDA has previously stepped in and issued stipulations in 2006, 2008 and 2009. PETA said in a statement it was calling for the National Institutes of Health to block federal funding for the company – and also asking the Food and Drug Administration to investigate potential violations of the Food, Drug, and Cosmetic Act. “SNBL’s incompetence and indifference have killed too many monkeys for too many years,” said Kathy Guillermo, PETA’s senior vice president of laboratory investigations. “PETA is calling for this laboratory to be stripped of its funding and shut down.”

Polychlorinated biphenyls (PCBs) are endocrine disrupting chemicals that disturb normal development of embryonic brains. In the present study, we evaluated the relationship between maternal plasma PCB concentration and infant behavioral characteristics in mother-infant interactions. We grouped 20 pregnant cynomolgus monkeys (Macaca fascicularis) into higher and lower PCB exposure groups; monkeys in the higher PCB group had PCB concentrations above 15 pg/g, which is representative of natural exposure levels. Maternal PCB concentration correlated negatively with infant behaviors (approach, look, proximity, locomotion) at the age of 6 months (p < .05), when an increase in these behaviors should normally occur. These results suggest that maternal PCB exposure may affect the development of infant social behavior in cynomolgus monkeys. Furthermore, this study provides primate evidence to support observations of associations between behavioral and learning disabilities and prenatal exposure to PCBs in humans. © 2010 Wiley Periodicals, Inc.

Our article summarizes a series of studies about fetal gyrification and its relation to cerebral growth in cynomolgus monkeys. Based on the cerebral growth (i.e., brain weight, cerebral volume, and frontooccipital length of the cerebral hemisphere) and the developmental pattern of gyrification in each sulcus of cynomolgus monkeys, we divided the gyrification process into four stages: Stage 1. Demarcation of cerebral lobes and limbic gyri; Stage 2. Demarcation of neocortical gyri; Stage 3. Emergence of secondary and tertiary sulci; and Stage 4. Growth of sulcal length and depth. Each stage of those gyrification processes was influenced by different developmental events, such as the emergence of corticocortical long-associative fiber tracts, cortical maturations, and subcortical white-matter development. This is the first report to systematically propose gyrification processes closely related to the order of phyologenetical development of the cerebral cortex in primates. © 2012 Wiley Periodicals, Inc.

Congenital Anomalies | Year: 2011

The present study aimed to quantitatively clarify the gross anatomical asymmetry and sexual dimorphism of the cerebral hemispheres of cynomolgus monkeys. While the fronto-occipital length of the right and left cerebral hemispheres was not different between sexes, a statistically significant rightward asymmetry was detected in the cerebral width at the perisylvian region in females, but not in males (narrower width of the left side in the females). An asymmetry quotient of the sulcal lengths revealed a rightward asymmetry in the inferior occipital sulcus and a leftward asymmetry in the central and intraparietal sulci in both sexes. However, the laterality of the lengths of other sulci was different for males and females. The arcuate sulcus was directed rightward in males but there was no rightward bias in females. Interestingly, the principle sulcus and lateral fissure were left-lateralized in the males, but right-lateralized in the females. The results suggest that lateralization patterns are regionally and sexually different in the cerebrum of cynomolgus monkeys. The present results provide a reference for quantitatively evaluating the normality of the cerebral cortical morphology in cynomolgus monkeys. © 2011 The Authors.

Drug metabolizing activities of cytochromes P450 (P450s, or CYPs) 3A4 and 3A5 in liver microsomes from the cynomolgus monkey [Macaca fascicularis (mf)] were investigated and compared with those of human P450 3A enzymes. Low activities for dealkylation of ethoxyresorufin and pentoxyresorufin were seen in recombinant monkey mfCYP3A4 and mfCYP3A5 and in recombinant human CYP3A4 and CYP3A5 expressed in bacterial membranes. Hydroxylation activities of mfCYP3A4 and mfCYP3A5 toward coumarin, paclitaxel, diclofenac, flurbiprofen, and S-mephenytoin were below detectable levels, as was also true for CYP3A4 and CYP3A5. Monkey mfCYP3A5 and mfCYP3A4 were highly active in bufuralol 1′-hydroxyl-ation. mfCYP3A5 was efficient at dextromethorphan O-demethylation, although human CYP3A5 was unable to catalyze this reaction. Apparent bufuralol 1′-hydroxylation and dextromethorphan O-demethylation activities of monkey liver microsomes were higher than those of human liver microsomes, possibly because of contributions of mfCYP3A5 to these P450 2D-dependent drug oxidations. mfCYP3A5 and CYP3A5 catalyzed midazolam 1′-hydroxylation at a low substrate concentration more efficiently than the corresponding CYP3A4. mfCYP3A5 had higher testosterone 6β-hydroxylase activity than mfCYP3A4, but the reverse relationship was observed in oxidation of nifedipine and hydroxylation of dexamethasone. These results demonstrate that monkey P450 3A enzymes have similar substrate selectivity to that of human P450 3A enzymes, but exhibit wider substrate selectivity toward P450 2D substrates.

(R)-Thalidomide was oxidized to 5-hydroxythalidomide and 5′-hydroxythalidomide by NADPH-fortified liver microsomes from humans and monkeys. (R)-Thalidomide was hydroxylated more efficiently than (S)-thalidomide. Recombinant human P450s 3A4, 3A5, and 3A7 and monkey P450s 3A8 and 3A5 (coexpressed with NADPH-P450 reductase in bacterial membranes) also catalyzed (R)-thalidomide 5-hydroxylation. Purified human P450s 2C19, 3A4, and 3A5 mediated (R)-thalidomide 5-hydroxylation at similar rates in reconstituted systems. P450 2C19 showed a rather nonsaturable substrate-velocity curve; however, P450s 3A4 and 3A5 showed sigmoidal curves. P450 also oxidized 5-hydroxythalidomide to an epoxide or dihydroxy compound. Liquid chromatography-mass spectrometry analysis revealed the formation of a glutathione conjugate from (R)- and (S)-5-hydroxythalidomide, catalyzed by liver microsomal P450s 3A4 and 3A5 in the presence of glutathione (assigned as a conjugate of 5-hydroxythalidomide formed on the phenyl ring). These results indicate that human P450s 3A4 and 3A5 mediate thalidomide 5-hydroxylation and further oxidation leading to a glutathione conjugate, which may be of relevance in the pharmacological and toxicological actions of thalidomide. © 2010 American Chemical Society.
