Short guide RNAs of catalytically inactive CRISPR associated 9 nuclease uses to express endogenous genes in human cells and bacteria. Chimeric nucleases help in precise and efficient genetic modifications leads to double strand breakage which can be repaired by DNA repair mechanism by homology directed repair and non-homology end joining. Here, we describe that single or multiple gRNAs direct dCas9 fused to a VP64 transcriptional activation domain to enhance the expression of endogenous human genes. Light-activated CRISPR-Cas9 effector (LACE) system induces dynamic regulation of genes in the presence of blue light. Targeted activation of endogenous neurogenic genes in transgenic mice leads to direct and efficient conversion of astrocytes into functional neurons in vivo. CRISPR-on can activate the endogenous IL1RN, SOX2, and OCT4 genes. Activation of genes was achieved by clusters of 3-4 sgRNAs that bind to the proximal promoters, result in their synergistic action in gene induction. Moreover, it fused with transcriptional activators in endogenous human INS (silenced gene with a fully methylated promoter). Multiplexed gene editing helps in metabolic engineering in yeast and CHO mammalian host. In this review we describe the applications and development of Cas9 for a variety of research or translational applications.

Establishment of Mouse Model for Obesity and Type 2 Diabetes and Expression of Secreted Frizzled Related Protein 4 (SFRP- 4) As A Biomarker
Type 2 diabetes is a metabolic, progressive and chronic disease associated with β-cell dysfunction and insulin resistance that leads to a decrease in insulin production followed by a decrease in insulin secretion. The main objective of the study was to develop a mouse model for type 2 diabetes that resembles most of the features of human T2D along with SFRP4 expression. Initially, all parameters to be studied in the research were measured and recorded prior to the start of the experiment. In order to accomplish this model, two groups of mice were fed high fat diet (HFD) and two groups were fed low fat diet (LFD) and tap water for a period of twelve weeks. Mice exposure to HFD has shown diet-induced obesity. At the end of the feeding period, the serum lipid profile including triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL) and total cholesterol (TC) of all experimental animals was evaluated. Significant increase in serum levels of TG, TC and LDL while low serum HDL levels were detected in HFD-fed mice serum. Similarly, the serum-SFRP4 level of all animals was measured using the ELISA kit. The serum level of SFRP4 was shown to be elevated (P < 0.01) in mice fed with HFD compared to control objects (P < 0.01). SFRP4 was associated with a high risk of developing type 2 diabetes. In conclusion, HFD dietary manipulation induces obesity, hyperglycemia, abnormal lipid profile and significant SFRP4 levels that ultimately lead to type 2 diabetes. SFRP4 may be a potential biomarker for early detection of type 2 diabetes.

DNA barcoding especially used in the field of molecular biology that uses primers with 500-700 segments to classify various species at molecular and genetic level. This review focuses on the role of DNA barcoding in conservation of biodiversity and current applications for the discovery of species. Some species of plants and animals remain unidentified at molecular level. DNA barcoding uses molecular tools for the discovery of species found in natural ecosystem and playing important role in biodiversity conservation. Genetic barcoding mainly focuses on conservation strategies on populations due to differences found in the mitochondrial DNA. The most commonly used DNA barcodes for the plant species are ITS, rbcL, psbA-trnH and matK. DNA barcodes has several applications for the detection of plants species by providing specific information about the taxa. There is need to use DNA barcoding in combinations with other sciences such as ecology and taxonomy methods for conservation of biodiversity. There is also need to use databases for appropriate storage of data about species to conserve biodiversity.

Role of DNA Barcoding in Plant Biodiversity Conservation
To prove the importance of DNA barcode one of the major point is that the genetic data is an important factor to improve the biodiversity conservation strategies and in fact at the different level of analysis in conservation biology many molecular tools. The aim of this review article is to access the role of DNA barcoding in biodiversity conservation in For the fine scale management of plant species, coral reefs, identification of cryptic and invasive species and regional management of fisheries in the field conservation biology molecular tools offer a great help. DNA barcoding had contribution in the conservation policy in such a way is that it came forward with the success of conservation action and other one is that it provide useful information about phylogenetic diversity and also about evolutionary history.

In India, cataract accounts for 80% of treatable blindness. Many factors such as ageing, altered blood electrolyte levels, diabetes mellitus, hypertension, nutrition and family history are involved in cataract genesis. Lens has a high content of potassium and low content of sodium. These two cations are in balance with each other due to Na+- K+-ATPase pump and lens capsular permeability. Normally to maintain lens membrane permeability, water electrolyte balance must be maintained intracellularly as well as extracellurly. Hence alteration in cation concentration of aqueous humors can be attributed to changes in the serum electrolytes, these ultimately affect lens metabolism leading to cataract formation. The composition of aqueous humour has been studied in various animals. Few human aqueous humour studies were conducted so far. An attempt is made here to establish a range for the electrolytes mentioned i.e. sodium, potassium, and chloride in the human aqueous humour in cataract patients and also compare it with serum electrolyte levels. It’s a case control study. Sample size includes 60. Aqueous humour and serum electrolytes (Na+, K+, Cl-) were estimated by ion selective electrode method. Sodium and Chloride levels were higher in serum compared to aqueous humour. Further sodium levels were increased from Grade I to Grade IV cataract. Biochemical parameters such as serum electrolytes can be used as marker to determine the risk involved in progression of cataract. This serum electrolytes measurement should be done as a routine screening investigation as it might help in predicting early development of senile cataract.

Background: Diabetes Mellitus is a syndrome characterised by a loss of glucose homeostasis from defective insulin secretion and its action; both are resulting in impaired metabolism of carbohydrate, lipid and protein. Diabetes mellitus, if uncontrolled, leads to many complications and the significant being atherosclerosis. Diabetes Mellitus could be treated by nutritional therapy/drug therapy and others. But the drug therapy would have its limitations and side effects. To overcome this, a herbal extract is recommended, such as Diallyl Disulphide (DADS) a principle compound of Garlic oil. Objectives: To assess the hypoglycaemic and hypolipidemic effects of Diallyl Disulphide (DADS) in alloxan-induced diabetic rats. Methods: Healthy adult Wister strain male albino rats, weighing around 100-150 grams were randomly selected from the animal house at BLDE University’s Shri B.M.Patil Medical College, Hospital and Research Centre, Bijapur, India. Diabetes was induced using alloxan and was treated with DADS. After a stipulated time, the rats were anaesthetised and sacrificed to collect the blood. Blood glucose and serum lipid profile were estimated using standard procedures. One way ANOVA followed by post hoc‘t’ test was done. Results: There was a significant decrease in the blood glucose, and lipid parameters of DADS treated alloxan-induced diabetic rats when compared to the alloxan-induced diabetic rats. Conclusion: From this study, it is concluded that the DADS a principle compound of garlic, definitely has the hypoglycaemic and hypolipidemic effect in diabetic rats, which is reducing the morbidity in diabetic cases without the adverse effects.
