Schizophrenia is a life-long,complex mental illness that still lacks satisfactory treatments.In recent years,increasing numbers of candidate biomarkers of schizophrenia occurrences and drug responses to schizophrenia therapies have been successfully identified by many omics studies.This review discusses the latest discoveries regarding effective drug targets and relevant drug classifications in schizophrenia.It also assesses our understanding of biomarkers for drug efficacy and adverse drug reactions in current schizophrenia treatments using omics technologies.Future applications in clinical practice have been proposed based on these new findings,and are now considered highly promising strategies to better treat schizophrenia.Finally,we explore several novel approaches that aim to reveal additional genetic signatures of schizophrenia using multi-omics data,which are hoped to improve the diagnosis and treatment of this illness in the future.

The ataxin-2 （ATXN2） gene is located on human chromo-some 12q24.1. In normal individuals, the coding region in exon 1 of this gene has fewer than 31 CAG repeats （Yu et al., 2005： Laffita-Mesa et al., 2012）. However, an abnormal expansion of CAG trinucleotide repeats results in the aggre-gation of polyglutamine （polyQ）, which causes spinocer-ebellar ataxia type 2 （SCA2） （Pulst et al., 1996）. The expanded alleles have more than 32 repeats in the affected individuals, and generally there is an inverse correlation between CAG repeat length and age of onset （Pulst et al., 1996）. SCA2 is an autosomal dominant inheritance neurodegenerative disease, whose major clinical feature is progressive cerebellar ataxia. Atrophies of the brainstem and frontal lobe have been frequently detected by magnetic resonance imaging （MRI） （Yamamoto-Watanabe et al., 2010）. This disease has the strong effect on sensory and motor control.
OBJECTIVE:To explore biomarkers of Pien Tze Huang(片仔癀)that ameliorated the symptoms of hepatic fibrosis.METHODS:Two groups of carbon tetrachloride-induced hepatic fibrosis(HF)mice model were constructed in our study:one group received PZH treatment and another group received no treatment.We performed this study to investigate the role of PZH in the regulation process of hepatic fibrosis.RESULTS:We identified 31 down-regulated and 39 upregulated mi RNAs using small RNA-seq analysis.Combining RNA-Seq data analysis,our study revealed 7 significant target genes(Sp4,Slc2 a6,Tln2,Hmga2,Ank3,Pax9,Fgf9).The results of real-time quantitative polymerase chain reaction analysis suggested that the expression level of 6 genes(Sp4,Tln2,Hmga2,Ank3,Pax9,Fgf9)were down-regulated compared to control group.On the other hand,the expression level of Slc2 a6 appeared to be up-regulated.The protein mass spectrometry showed that PZH group had lower protein expression of Tln2 compared to control group.CONCLUSION:We identified 7 genes that were significantly related to PZH response in HF mice using multiple conjoint analysis methods.These genes could participate in underlying regulation mechanism of hepatic fibrosis during PZH treatment.
