| Outline of Research at the Start |
1. Elucidation of the relationships of STB/HAP1 with Steroid hormone receptors in vivo.
2. Assessments of effects of STB/HAP1 on serum hormone concentration.
3. Examination of effects of STB/HAP1 on the number of SHR-immunoreactive neurons.
4. Clarification of the effects of STB/HAP1 and steroid hormone-related functions.
5. Action in the event that the research does not progress as originally planned.

| Outline of Annual Research Achievements |
Our previous in vitro findings suggest that STB/HAP1 could be related to the subcellular regulation of SHRs. In this research project to clarify the in vivo effects of STB/HAP1 in regulating or protecting the functions of sex steroids via their receptors; AR and ER, I examined the detailed in vivo immunohistochemical relationships of HAP1 with AR, and ER in the preoptic area and hypothalamic areas in adult mice. I found that HAP1 was highly coexpressed with both the sex steroid receptors in the different brain regions, which is suggestive of HAP1 modification of the steroidal functions in the brain.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
I have completed my first objective, clarifying the in vivo relationships of STB/HAP1 with different steroid receptors. I have presented my research findings at several academic conferences.
|
| Strategy for Future Research Activity |
1. Assessments of effects of STB/HAP1 on serum hormone concentration.
2. Examination of effects of STB/HAP1 on the number of SHR-immunoreactive neurons.
3. Clarification of the effects of STB/HAP1 and steroid hormone-related functions.
4. Action if the research has yet to progress as planned initially.
