Nowadays, drug discovery is a long process which includes target identification, validation, lead optimization, and many other major/minor steps. The huge flow of data has necessitated the need for computational support for collection, storage, retrieval, analysis, and correlation of data sets of complex information. At the beginning of the twentieth century, it was cumbersome to elaborate the experimental findings in the form of clinical outcomes, but current research in the field of bioinformatics clearly shows ongoing unification of experimental findings and clinical outcomes. Bioinformatics has made it easier for researchers to overcome various challenges of time-consuming and expensive procedures of evaluation of safety and efficacy of drugs at a much faster and economic way. In the near future, it may be a major game player and trendsetter for personalized medicine, drug discovery, drug standardization, as well as food products. Due to rapidly increasing commercial interest, currently probiotic-based industries are flooding the market with a range of probiotic products under the banner of dietary supplements, natural health products, food supplements, or functional foods. Most of the consumers are attracted toward probiotic formulations due to the rosy picture provided by the media and advertisements about high beneficial claims. These products are not regulated by pharmaceutical regulatory authorities in different countries of origin and are rather regulated as per their intended use. Lack of stipulated quality standard is a major challenge for probiotic industry; hence there would always be a possibility of marketing of ineffective and unsafe products with false claims. Hence it is very important and pertinent to ensure the safety of probiotic formulations available as over-the-counter (OTC) products for ignorant society. At the same time, probiotic industry, being in its initial stages in developing and underdeveloped countries, requires to ensure safe, swift, and successful usage of probiotics. In the absence of harmonized regulatory guidelines, safety, quality, as well as the efficacy of the probiotic strain does not remain a mandate but becomes a choice for the manufacturer. Hence there is an urgent need to screen already marketed probiotic formulations for their safety with respect to specific strains of probiotic. Various conventional methods used by the manufacturers for the identification of probiotic microbes create a blurred image about their status as probiotics. The present manuscript focuses on a bioinformatics-based technique for validation of marketed probiotic formulation using 16s rRNA sequencing and strain-level identification of bacterial species using Ez Texan and laser gene software. This technique gives a clear picture about the safety of the product for human use.
如今,药物研发是一个漫长的过程,包括靶点识别、验证、先导化合物优化以及许多其他主要/次要步骤。大量的数据使得对复杂信息数据集的收集、存储、检索、分析和关联需要计算支持。在20世纪初,以临床结果的形式阐述实验结果很麻烦,但生物信息学领域目前的研究清楚地表明,实验结果和临床结果正在不断统一。生物信息学使研究人员能够以更快、更经济的方式克服评估药物安全性和有效性的耗时且昂贵程序的各种挑战。在不久的将来,它可能成为个性化医疗、药物研发、药物标准化以及食品领域的主要参与者和引领者。由于商业利益迅速增加,目前基于益生菌的产业打着膳食补充剂、天然健康产品、食品补充剂或功能性食品的旗号,向市场大量倾销一系列益生菌产品。大多数消费者被媒体和广告所描绘的关于益生菌诸多有益功效的美好图景所吸引。这些产品在不同原产国不受药品监管当局的监管,而是根据其预期用途进行监管。缺乏规定的质量标准是益生菌产业面临的一个重大挑战;因此,总是有可能销售无效且不安全但却有虚假宣称的产品。因此,对于无知的社会大众来说,确保作为非处方(OTC)产品的益生菌制剂的安全性非常重要且相关。与此同时,益生菌产业在发展中国家和不发达国家尚处于起步阶段,需要确保益生菌的安全、快速和成功使用。在缺乏统一监管指南的情况下,益生菌菌株的安全性、质量以及功效不再是强制性要求,而成为制造商的一种选择。因此,迫切需要对已上市的益生菌制剂进行特定益生菌菌株安全性的筛选。制造商用于鉴定益生菌微生物的各种传统方法使其作为益生菌的地位变得模糊不清。本手稿重点介绍一种基于生物信息学的技术,用于通过16s rRNA测序验证已上市的益生菌制剂,并使用Ez Texan和激光基因软件对细菌物种进行菌株水平鉴定。该技术能清楚地表明产品对人类使用的安全性。
