Weights were measured and recorded at 4 weeks or less and 4 to 7 weeks. compared to woman crazy type (WT) mice by demonstrating improved marble-burying activity (p=0.0025) and a pattern towards increased grooming behavior (p=0.06). Male haploinsufficient mice exhibited no behavioral changes Rabbit polyclonal to WBP2.WW domain-binding protein 2 (WBP2) is a 261 amino acid protein expressed in most tissues.The WW domain is composed of 38 to 40 semi-conserved amino acids and is shared by variousgroups of proteins, including structural, regulatory and signaling proteins. The domain mediatesprotein-protein interactions through the binding of polyproline ligands. WBP2 binds to the WWdomain of Yes-associated protein (YAP), WW domain containing E3 ubiquitin protein ligase 1(AIP5) and WW domain containing E3 ubiquitin protein ligase 2 (AIP2). The gene encoding WBP2is located on human chromosome 17, which comprises over 2.5% of the human genome andencodes over 1,200 genes, some of which are involved in tumor suppression and in the pathogenesisof Li-Fraumeni syndrome, early onset breast cancer and a predisposition to cancers of the ovary,colon, prostate gland and fallopian tubes (p 0.05). Elevated plus-maze and open-field test results showed no overt anxiety-like behavior in haploinsufficient mice irrespective of sex (p 0.05, both). No variations in brain excess weight were found in haploinsufficient mice compared to WT mice (p 0.05). However, female haploinsufficient mice weighed more than female WT mice in the 4 to 7 weeks age range (p=0.0051). Male haploinsufficient mice showed no variations in excess weight compared to male WT mice (p= 0.05) at any age range examined. Summary haploinsufficiency led to sex-dependent, compulsive-like behavioral changes inside a murine model. Interestingly, haploinsufficiency also led to a sex-dependent increase in body excess weight. These results exposed a requirement for AKAP13 in murine behavior, particularly in female mice, and is the 1st statement of AKAP13 involvement in murine behavior. Long term studies may show AKAP13 involvement in the pathophysiology of OCD in female humans and may contribute to a better understanding of the part of AKAP13 and sex hormones in the development and exacerbation of OCD. null mutation (haploinsufficient (haploinsufficient mice to their WT littermates. Mice were housed with same sex littermates, with no more than 5 mice per cage. Mice were tested between 2 and 7 weeks old. Vivarium conditions included controlled heat between 22C25 C and a 12:12 hour light/dark cycle. Food and water were available haploinsufficient mice and WT mice were observed both pre- and post-novel object placement. The open-field test was carried out as previously explained with nominal modifications (Li et al., 2006). Screening required the following: enclosed test package (50cm 50cm 53cm), blue screw cap (33mm) novel object, video recorder and video tracking software (ANY-maze software, San Diego Devices, San Diego, CA). The box consisted of 4 walls and a floor; the top of the box was left uncovered to video record the mouses physical movements. The floor area was pre-divided into zones marked by black tape: center zone and peripheral zone. For testing, each mouse was placed alone, under video surveillance, in the open-field at the periphery, and tested for 15 minutes. The recordings were divided into two segments (pre-novel object and post-novel object placement). The pre-object PF-3758309 segment lasted for 10 minutes PF-3758309 prior to placing the novel object into the 20cm 20cm center zone, whereas the post-novel object segment was recorded for an additional 5 minutes. The number of times the animal defecated or urinated during testing was recorded. Movement within the open-field was separated into five categories: a) Wall time (time in the peripheral zone), b) Center latency time (time until first entry to the center zone), c) Center time (amount of time in the center zone), d) Center entries (number of times the mouse moved into the center zone) and e) number of defecations and urinations. 2.2.4. Elevated plus-maze As another test for stress, we uncovered both male and female mice to the elevated plus-maze as previously described (Pellow et al., 1985; Walf et al., 2007). The maze was elevated 38cm from the floor and was comprised of four arms (two open without walls and two enclosed by 15cm high walls). Each arm measured (30cm 5cm) (Li et al., 2006). AnyMaze software was used PF-3758309 to track the time each mouse spent in the closed arm, open arm, and center of the maze. 2.3. Weight evaluations Animal and brain weights were obtained using standard procedures and gear from adult mice between 3-9 months old. We wanted to determine whether any gross anatomical changes were present in the brains of haploinsufficient mice of both sexes. Mouse brains, including the olfactory bulb, were collected post-mortem; standard dissection procedures were followed. The fresh brains were weighed pre-paraffin embedding. Adult haploinsufficient mice appeared visibly larger in size than WT mice. To test our hypothesis, haploinsufficient and WT mice, of both sexes, were observed for up to 6 months of age. Weights were measured and recorded at 4 months or less and 4 to 7 months. For body weight measurements, mice were placed into weigh boats (14.6cm 7.7cm). Weigh boats were tared before mouse or organ placement. 2.4. Statistical analyses Data are presented as mean standard error of the mean (SEM). SAS version 9.4 (SAS Institute, Cary, NC) was used for all statistical analyses. Differences were considered significant when p PF-3758309 0.05. ANOVA was used to test for genotype effects, sex effects, and age effects, and the conversation.
