Study on the Effect of PRKCB1 Modulating Inflammatory Factors & the Role

Status Recruiting

Clinical Trial Summary

Depressive disorder is known as being accompanied with the activation of immune system which could lead to a series of changes including the neuron apoptosis, synapses transmission inhibition and emotional symptoms. The activation of protein kinase C (PKC) can reverse the immune/inflammatory process and restore the neuroplasticity and neurotransmitters transmission. Based on our finding that patients with major depressive disorder (MDD) showed a significantly lower gene expression of PRKCB1, while the PKC activation mediated by PRKCB1, we hypothesize that PRKCB1 contribute to the development of MDD and treatment response by its specific expression in brain, regulating ERBB, Chemokine signaling pathways and PKC activation during the neuroinflammatory process. In the present study, we aim to evaluate and verify the regulation effect of PRKCB1 on the neuroimmune and inflammatory mechanism in depressive disorder by a serious of studies focus on PRKCB1 gene expression modulating process and different downstream biomarkers which associated with PRKCB1 effect, combined with the specified treatment (plus omega-3 poly unsaturated fat acids). This study may provide scientific evidences for using neuroinflammatory biomarkers to diagnose MDD, as well as personalized treatment.

Clinical Trial Description

(1）To find out the differences of expression of mRNA, lncRNA, miRNA and proteins of PRKCB1 between patients with depressive disorder and healthy subjects.

(2) Patients with depressive disorders will be randomized into two groups that they will be treated with escitalopram or escitalopram plus Omega-3 PUFAs. To observe the effects of Omega-3 PUFAs on PRKCB1 and related neuroimmune/neuroinflammatory pathway which may improve understanding the relationship between neuroinflammatory regulation and depressive disorder treatment. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
