From Cirrhosis to the Dysbiosis (A Loop of Cure or Complications?).

Gut dysbiosis and liver cirrhosis are two corelated complications that highly disturbs the metabolism of a normal human body. Liver cirrhosis is scarring of the hepatic tissue and gut dysbiosis is the imbalance in the microbiome of the gut. Gut dysbiosis in cirrhosis occurs due to increased permeability of the intestinal membrane which might induce immune responses and damage the normal functioning of the body. Dysbiosis can cause liver damage from cirrhosis and can further lead to liver failure by hepatocellular carcinoma. In this review we discuss if eubiosis can revert the poorly functioning cirrhotic liver to normal functioning state? A normal microbiome converts various liver products into usable forms that regulates the overgrowth of microbiome in the gut. The imbalance caused by dysbiosis retards the normal functioning of liver and increases the complications. To correct this dysbiosis, measures like use of antibiotics with probiotics and prebiotics are used. This correction of the gut microbiome serves as a ray of hope to recover from this chronic illness. In case of alcohol induced liver cirrhosis, intervention of microbes can possibly be helpful in modulating the addiction as well as associated complications like depression as microbes are known to produce and consume neurotransmitters that are involved in alcohol addiction. Hence a correction of gut liver brain axis using microbiome can be a milestone achieved not only for treatment of liver cirrhosis but also for helping alcohol addicts quit and live a healthy or at least a near healthy life.

Association of the CDH13 gene variant rs9940180 with schizophrenia risk in North Indian population.

BACKGROUND AND OBJECTIVES: Cadherin13 (CDH13) is an uncommon cadherin family member, lacking a transmembrane domain, and attaches via a glycosylphosphatidylinositol anchor to the peripheral surface of the cell membrane. CDH13 plays an important role in the development and maintenance of axonal growth cones, synapse morphogenesis, and the embryonic neural tube. Cadherin superfamily genes have been associated with many neuropsychiatric diseases. Studies have shown the Cadherin13 gene as a risk locus for Schizophrenia (SCZ). In this study, we investigated CDH13 gene variants rs7204454 in the promotor region and rs9940180 in the intronic region of the gene with susceptibility to SCZ risk in the population of Jammu region of J&K, India. METHODS: The genotyping was performed using TaqMan assay, where 560 individuals, comprising 164 patients and 396 healthy controls, were genotyped. RESULTS: The result of the study suggested rs9940180 was significantly found to be associated with Schizophrenia and the "C" allele of rs9940180 was associated with increased risk for SCZ (P = 0.03817; OR = 1.527; 95% CI, 1.022-2.28) whereas the other variant rs7204454 of CDH13 gene did not show significant association with schizophrenia risk with P = 0.8827, OR = 0.582-1.33 at 95% CI. CONCLUSION: This is the first report suggesting a significant association of polymorphism at CDH13 rs9940180 with Schizophrenia in the Dogra population group of the Jammu region. The current study offers a piece of important information on the genetic reason for CDH13 in the Jammu population of J&K. Also, it supports the GWAS findings on the correlation of CDH13 in schizophrenia.

Genetic evidence for association of NOTCH4 variant rs2071287 with schizophrenia susceptibility in the North Indian population.

Background: Neurogenic locus notch homolog 4 (NOTCH4) regulates signaling pathways associated with neuronal maturation, a process involved in the development and patterning of the central nervous system. The NOTCH4 gene has also been identified as a possible susceptibility gene for schizophrenia (SCZ). Aim: The study aimed to determine the association of NOTCH4 polymorphisms with the risk of SCZ in the North Indian population of the Jammu region. Methods: The single nucleotide polymorphism genotyping for NOTCH4 variant rs2071287 was done by Sanger's sequencing method, and the other variant rs3131296 was done by TaqMan assay method for 207 SCZ cases and 304 healthy controls of North Indian origin. Results: This association study suggested that the rs2071287 was found to be significantly associated with SCZ. Moreover, the GG genotype of rs2071287 was observed to be associated with a higher risk for SCZ (P-value = 6.45 × 10 - 5; OR = 1.71; 95% CI, 1.31-2.24). Conclusion: To establish the potential biomarker role of this variant, large-scale association analyses in other populations is required.
