Laboratory Information Management System for Biotech Labs: Significance & Benefits

Article | July 20, 2022

If you have ever visited the testing laboratory of a large biotechnology company, you will be aware that managing the laboratory's operations single-handedly is no easy task. The greater the size of a lab, the more research and testing activities it must accommodate. A variety of diagnostic tests are prescribed for patients in order to detect various diseases. For example, it may include blood glucose testing for diabetics, lipid panel, or liver panel tests for evaluating cardiac risk and liver function, cultures for diagnosing infections, thyroid function tests, and others. Laboratory management solutions such as laboratory information management systems (LIMS) and other software play a significant role in managing various operational data at biotech laboratories. It is one of the important types of software developed to address thedata management and regulatory challenges of laboratories. The software enhances the operational efficiency of biotech labs by streamlining workflows, proper record-keeping, and eradicating the need for manually maintaining data. What Are the Benefits of Laboratory Information Management Software in Biotechnology? As the trends of digitization and technology continue to create deeper inroads into the biotechnology sector, a significant rise in the adoption of innovative medical software solutions, such as LIMS, is being witnessed for managing research data, testing reports, and post-research results globally. Here are a few reasons that are encouraging biotech facilities to adopt LIMS solutions Real-Time Data Collection and Tracking Previously, collecting and transporting samples was a tedious and time-consuming task. However, the adoption of LIMS with innovative tracking modules has made the job easier. The real-time sample tracking feature of LIMS has made it possible for personnel to collect the research data in real-time and manage and control the workflow with a few mouse clicks on the screen. Increase Revenue LIMS makes it possible to test workflows while giving users complete control over the testing process. A laboratory is able to collect data, schedule equipment maintenance or upgrades, enhance operational efficiency, and maintain a lower overhead with the help of the LIMS, thereby increasing revenue. Streamlined Workflow With its completion monitoring, LIMS speeds up laboratory workflows and keeps track of information. It assigns tasks to the specialist along with keeping a real-time track of the status and completion of each task. LIMS is integrated into the laboratory using lab information, which ultimately speeds up internal processes and streamlines the workflow. Automatic Data Exchange LIMS solutions store data in a centralized database. Automated transfer of data between departments and organizations is one of the major features of LIMS. Through its automated information exchange feature, LIMS improves internal operations, decreases the reporting time for data sharing, and assists in faster decision-making. Final Thoughts As the healthcare sector continues to ride the wave of digital transformation, biotech laboratories are emphasizing adopting newer technologies to keep up with the changes. Citing this trend, laboratory information management systems are becoming crucial for biotech and medical organizations for maintaining research data, instant reporting, and managing confidential, inventory, and financial data with centralized data storage.

Researchers identify new way to make cancer self-destruct

Medicalxpress | July 01, 2019

For years, researchers have been trying to target a gene called MYC that is known to drive tumor growth in multiple cancer types when it is mutated or over-expressed, but hitting that target successfully has proven difficult. Now researchers in the Perelman School of Medicine of the University of Pennsylvania have identified a new pathway that works as a partner to MYC and may be its Achilles' Heel. The pathway involves a protein called ATF4, and when it's blocked, it can cause cancer cells to produce too much protein and die. These findings in cell lines and mouse models could point the way toward a new therapeutic approach as inhibitors that can block synthesis of ATF4 already exist. The journal Nature Cell Biology published the findings today. MYC is a gene that controls normal cell growth, but when it is mutated or amplified in cancer, it sets off a chain reaction that helps tumors grow uncontrollably. While there is currently no specific way to target it, previous research has focused on blocking other steps in the chain as a workaround to impede tumor growth. The team, led by Constantinos Koumenis, Ph.D., the Richard Chamberlain Professor of Radiation Oncology and vice chair and research division director of Radiation Oncology, have previously shown that in certain tumors, one of these steps is regulated by a kinase called PERK, which activates ATF4. However, in this new study, they've shown that blocking PERK does not always stop tumor growth because MYC actually controls a second process that can work in parallel as a redundancy in the system. This study identified this second kinase, which is called GCN2.
