Project description:Neuronal activity is altered in several neurological and psychiatric diseases. Upon depolarization not only neurotransmitters are released but also cytokines and other activators of signaling cascades. Unraveling their complex implication in transcriptional control in receiving cells will contribute to understand specific central nervous system (CNS) pathologies and will be of therapeutical interest. In this study we depolarized mature hippocampal neurons in vitro using KCl and revealed increased release not only of Brain-derived neurotrophic factor (BDNF), but also of Transforming growth factor beta (TGFB). Neuronal activity together with BDNF and TGFB controls transcription of DNA modifying enzymes specifically members of the DNA-damage-inducible (Gadd) family, Gadd45a, Gadd45b, and Gadd45g. MeDIP followed by massive parallel sequencing and transcriptome analyses revealed less DNA methylation upon KCl treatment. Thereby, psychiatric disorder-related genes, namely Tshz1, Foxn3, Jarid2, Per1, Map3k5, and Arc are transcriptionally activated and demethylated upon neuronal activation. To analyze whether misexpression of Gadd45 family members can be associated with psychiatric diseases, we applied unpredictable chronic mild stress (UCMS) as established model for depression to mice.UCMS lead to a reduced expression of Gadd45 family members. Taken together, our data demonstrate that Gadd45 family members are new putative targets for UCMS treatments.

Project description:This study is a prospective and effective research study. The aim is to assess the difference in the quality of life of the family members of patients with colorectal cancer after application of follow-up disease management using mobile network terminals and routine clinical treatment follow-up management. The hypothesis is that the application of mobile-based disease management system significantly improves the quality of life of the patients’ family members, thereby improving the quality of life of the patients’ families.
Approximately 100 families of colorectal cancer patients who had been diagnosed as high-risk stage II or stage III and required adjuvant chemotherapy XELOX regimen within 6 months after initial diagnosis were randomly assigned to the control and study groups at a 1: 1 ratio, with approximately 50 cases in the control group and about 50 patients in the study group. The reason for choosing these tumors is because the patients with these tumors will present a series of clinical symptoms during the treatment, which requires family members to take care of them. All patient and their family demographics, questionnaires on quality of life of patient’s family, adverse events and other information will be collected.
The study uses a network-centric randomization system. In the randomization process, stratified randomization will be carried out according to the education level of the patient’s family members (junior college degree or above vs. below college degree). The family members of the patients participating in the study will be randomly assigned to the tumor patient management platform or clinical routine treatment follow-up group.
Family members of all patients will be followed up to 2 months after randomization, or withdrew from the study (with the preceding events as the end point). Unless the patient’s family member withdraws from the study, lost to follow-up, or the study is terminated, the patient is considered to be in the study. Family members of patients who are randomly assigned to the full management platform need to participate in a 60 minutes concentrated training session for 27 days, taught by experts online. The content of the lectures includes medical treatment guidelines, pain relief, family rehabilitation, family communication, family roles, early screening prevention, Medical insurance and other aspects. The contents of the online courses are: 1) Doctors are also mortal; 2) New medicines and new therapies; 3) Alternative therapies; 4) Don’t panic during the operation; 5) Pain relief; 6) Side effects of treatment; 8) About the truth; 9) New topics; 10) Anti-cancer cost-effectiveness; 11) Medical insurance; 12) Commercial medical insurance; 13) Exercise and rehabilitation; 14) Nutrition and Foods to increase leukocytes level ; 15) Long-term persistence; 16) Acceptance Change; 17) Two new roles; 18) Future expectation.
Project description:THAP1 is a transcription factor and its mutations are responsible for DYT6 dystonia. However, how THAP1 mutations lead to these gene expression alterations and whether the gene expression changes are also reflected in the brain of THAP1 patients are still unclear. In this study we used epigenetic and transcriptomic approaches combined with multiple model systems to uncover the function of THAP1 and the potential pathogenesis of DYT6 dystonia. THAP1 mutations lead to dysregulation of genes mainly through regulation of SP1 family members, SP1 and SP4, in a cell type dependent manner.

Project description:Whole Exome Sequencing of IOP family members
Project description:To assess variation and inheritance of genome-wide patterns of DNA methylation simultaneously in humans, we applied reduced representation bisulfite sequencing (RRBS) to somatic DNA from six members of a three-generation family. Reduced representation bisulfite sequencing was applied to genomic DNA from leukocytes of 6 family members and two unrelated individuals.
