The completion of the first draft of the human genome has provided an unprecedented opportunity to understand the genetic and molecular basis of disease. Parallel developments of new biological technologies, such as transcript profiling, allow scientists to examine almost any biological system in high molecular resolution. Novel therapeutic interventions are being developed and evaluated as a result of this research which will be the basis of innovative pharmaceuticals of the future. Despite many advances in medicine, disease burdens remain significant in both developed and emerging countries.

Epigenetic Approaches in Drug Discovery, Development and Treatment

Prior efforts using genomics to inform drug discovery that is, expressed sequencing tag profiling and genome-wide association studies have yielded an array of potential targets but have encountered difficulty in translating these discoveries into clinically efficacious drugs. Precision medicine marks a new relationship between genomics and drug discovery, one that provides both insights into the mechanisms and potential treatment options of a single patient's disease. Oncology has been the leader in the field of precision medicine, with a multitude of successful examples of targeted treatments and immunotherapies available for a wide range of cancers.

Genomics in Drug Development

Establishment of a normal phenotype involves dynamic epigenetic regulation of gene expression that when affected contributes to human diseases. On a molecular level, epigenetic regulation is marked by specific covalent modifications acetylation, methylation, phosphorylation, sumoylation, PARylation and On a molecular level, epigenetic regulation is marked by specific covalent modifications acetylation, methylation, phosphorylation, sumoylation, PARylation and ubiquitylation of DNA and its associated histones. Studies also suggest the influence of such epigenetic modifications on non-coding RNA expression implicated in normal and diseased phenotypes. Epigenetic control of genetic expression is a reversible process essential for normal development and function of an organism. Alteration of epigenetic regulation leads to various disease forms such as cancer, diabetes, inflammation and neuropsychiatric disorders.


Historically, drug development and clinical practice have focused on Genetics- and Genomics-Based Drug Target Identification and Efficacy Biomarkers ​%%20BIO,%20Biomedtracker,%20Amplion%pdf.


Drug discovery

Analyzing historical pipeline data, Nelson et al. Taking advantage of recent clinical development advances and rapid growth in GWAS datasets, we extend the original work using updated data, test whether genetic evidence predicts future successes and introduce statistical models adjusting for target and indication-level properties. When causal genes are clear Mendelian traits and GWAS associations linked to coding variants , we find the use of human genetic evidence increases approval by greater than two-fold, and, for Mendelian associations, the positive association holds prospectively.

Molecular biomarkers are increasingly being used to identify subgroups of patients that have a higher chance of benefiting from targeted therapies. Identification of predictive biomarkers and development of companion diagnostics to accompany targeted agents have been shown to significantly improve the efficacy and approval rate of these novel therapies, making treatment decisions more personalized to individual patients. Mutations of epidermal growth factor receptor EGFR and rearrangements of anaplastic lymphoma kinase ALK in non-small-cell lung cancer and of BRAF in melanoma provide great examples of driver mutations defining patient subgroups that respond to specific therapeutic agents.

Genomics drugs in clinical trials

Bioinformatic analysis can not only accelerate drug target identification and drug candidate screening and refinement, but also facilitate characterization of side effects and predict drug resistance. High-throughput data such as genomic, epigenetic, genome architecture, cistromic, transcriptomic, proteomic, and ribosome profiling data have all made significant contribution to mechanism-based drug discovery and drug repurposing. Accumulation of protein and RNA structures, as well as development of homology modeling and protein structure simulation, coupled with large structure databases of small molecules and metabolites, paved the way for more realistic protein-ligand docking experiments and more informative virtual screening.

Они глупы и тщеславны, это двоичные самовлюбленные существа. Они плодятся быстрее кроликов. В этом их слабость - вы можете путем скрещивания отправить их в небытие, если, конечно, знаете, что делаете. Увы, у этой программы такого тщеславия нет, у нее нет инстинкта продолжения рода. Она бесхитростна и целеустремленна, и когда достигнет своей цели, то скорее всего совершит цифровое самоубийство.  - Джабба театральным жестом указал на громадный экран.  - Дамы и господа, - он опять тяжело вздохнул, - перед вами компьютерный агрессор-камикадзе… червь.

Я думаю, он собирался оставаться поблизости и вовремя все это остановить. Глядя на экран, Фонтейн увидел, как полностью исчезла первая из пяти защитных стен. - Бастион рухнул! - крикнул техник, сидевший в задней части комнаты.  - Обнажился второй щит. - Нужно приступать к отключению, - настаивал Джабба.

Именно он и подал ручную команду на отзыв Следопыта. Вопрос насколько .

Я спас вас, сделав это заранее. Можешь представить себе последствия, если бы это обнаружилось, когда Попрыгунчик был бы уже внедрен. - Так или иначе, - парировала Сьюзан, - теперь мы имеем параноиков из Фонда электронных границ, уверенных, что черный ход есть во всех наших алгоритмах.
