Abstract
The invention relates to identification of potential biomarkers and drug targets in brain plasticity related disorders. In particular, the invention describes a system level model of brain plasticity related disorders in the fruit fly Drosophila melanogaster, thereby identifying potential biomarkers and drug targets in epileptogenesis and associated conditions. The invention also provides a means of screening therapeutic agents against epilepsy and related disorders using gene expression profiling in Drosophila.
Claims
1. A method for identification of potential biomarkers for epileptogenesis and related brain plasticity disorders, said method consisting the steps of:
[a] treating Drosophila flies with either convulsant or antiepileptic drugs in a chronic manner;
[b] extracting RNA from the heads of treated flies of step [a] at several time-points secondary to drug treatments*
[c] generating microarray gene expression profiles specific for convulsant and antiepileptic drugs respectively using the RNA extracted from step [b];
[d] identifying genes that are up- and down-regulated by convulsant and antiepileptic drugs from the microarray of step [c];
[e] identifying genes which are down- and up-regulated respectively by convulsant and antiepileptic drugs in the fly model and the homologs down regulated in established rodent models of epilepsy development as candidate biomarkers of epileptogenesis.
2. A method for identification of potential drug targets against epileptogenesis and related brain plasticity disorders, said method consisting the steps of:
(a) comparing fly genes that are regulated by different antiepileptic drugs in Drosophila head after categorizing them on the basis of biological processes they represent;
(b) identifying fly genes that are similarly regulated by different antiepileptic drugs as potential drug targets;
(c) validating the candidature of the potential drug targets by confirming the biological processes they represent.
3. A method according to claim 1, wherein products of Drosophila genes Aldolase (CG6058) and Glutathione S transferase D4 (CGl 1512) are identified as biomarkers of kindling- epileptogenesis like plasticity in the fly model.
4. A method according to claim 1, wherein the products of homologs of fly genes CG6058 and CGl 1512 are identified as potential biomarkers of epileptogenesis and associated disorders.
43
5. A method according to claim 2, wherein products of Drosophila genes Glutamate oxaloacetate transaminase 2 (CG4233) and Sorbitol dehydrogenase 1 (CGl 982) are identified as targets of antiepileptic drugs in fly model of kindling-epileptogenesis like plasticity.
6. A method according to claim 2, wherein products of homologs of fly genes CG4233 and CGl 982 are identified as potential targets for developing drugs against epilepsy and related disorders.
7. Use of products of human homologs of fly genes CG6058 and CGl 1512 as biomarkers of epileptogenesis in at-risk individuals.
8. Use of products of human homologs of fly genes CG4233 and CGl 982 as drug targets for developing therapeutic agents against epilepsy and related brain disorders.
