Researchers identify potential new combination treatment for pancreatic cancer

Medical Xpress | March 20, 2019

Researchers from UCLA's Jonsson Comprehensive Cancer Center have identified a possible new therapeutic strategy using two types of drug inhibitors at once to treat one of the world's deadliest cancers. The combination approach uses one drug that inhibits the process—known as lysosome—that allows cancer cells to recycle essential nutrients to survive, and another drug that blocks the pathway used to repair DNA. Researchers found the approach to be promising after testing it on pancreatic cancer cells and mice in the laboratory. Pancreatic cancer, which is the third leading cause of cancer-related deaths in the United States, is known to be highly resistant to treatments. The lack of effective treatments also suggests there is an inadequate understanding of the biologic complexity of the disease and the mechanisms to explain why this type of cancer often becomes resistant to therapies that work in treating other types of cancers. Because of these limitations, researchers have sought to better understand how the cancer cell pathways work to help identify potential new targets for therapies. Pancreatic cancer cells rely on lysosome-dependent pathways, which are an essential component of autophagy, where cancer cells break down and recycle some of their own components for fuel. Understanding the underlying mechanism and impact of inhibiting this pathway can lead to new treatment strategies for the disease.

Roche Signs an Agreement with Sysmex to Bring Haematology Testing Innovations Globally

Roche | January 25, 2021

Roche declares that, on 14 December, 2020, it marked a Global Business Partnership Agreement* (GBP) with Sysmex. Under this new system, the gatherings restored their obligation to the long standing Distribution, Sales and Service (DSS) arrangement, permitting Roche to keep on disseminating Sysmex hematology items, including instruments and reagents. This GBP sees the presentation of an IT Solutions Collaboration Agreement. In the recently characterized joint effort, the two organizations have consented to use their separate IT stages to improve client experience, in the short to mid-term, with a more drawn out term aspiration to utilize the IT frameworks to prompt improved clinical dynamic. The GBP arrangement will run until the finish of 2030. “Roche is committed to supporting improvements in haematology testing, which helps patients with the diagnosis and management of blood diseases, as diverse as anemia and leukaemia”, said Thomas Schinecker, CEO Roche Diagnostics. “Extending our longstanding partnership with Sysmex underscores our unique synergy and our objective to offer our customers high-quality haematology solutions to improve the testing efficiency in central laboratories in hospitals and commercial laboratories, ultimately benefiting the millions of patients living with blood disorders.” The burden of blood disorders is exceptionally high, for patients as well as for society overall. Ongoing examinations assessed that, in Europe, 80 million individuals experience the ill effects of hematological issues and the monetary effect of blood issues in Europe adds up to EUR 23 billion every year, generally in medical services use. Improved administration is a vital factor to neutralize the ascent of this monetary weight for healthcare and society.

CosmosID Launches Accurate and Easy Functional Microbiome Analysis with New Software Platform, CosmosID-HUB: Microbiome

CosmosID | September 27, 2021

A complete analysis of the microbiome should combine taxonomic profiling ("who is there?") with functional characterization ("what are they doing?") to discover the capabilities of an entire community of microorganisms. But research teams often require specialized training and extensive computational infrastructure to establish an in-house suite of tools for processing shotgun metagenomic data – and even with the right know-how, the processing can be both time-consuming and challenging. CosmosID®, known for the most accurate, multi-kingdom, strain level taxonomic profiling technology, has added a functional analysis module to its popular online user-interface, renamed 'CosmosID-HUB: Microbiome'. Now, in addition to microbiome sequencing services out of its Germantown, MD, laboratory, its industry-leading team of bioinformaticians and software developers, has unveiled a suite of new features for seamless analysis of the genomic potential of microbial communities: Direct links from the platform to MetaCyc and GO terms databases. Data import via direct upload, Illumina BaseSpace & automated SRA import from NCBI with analysis speeds up to 19X faster than open-source tools. Find your organism or gene/pathway of interest with search functions, exportable charts & visualizations. Comparative analysis software, complete with dynamic charts, graphs, and statistical significance testing. Easy-to-navigate user interface OR command-line access. Applicable to almost any sample type Applicable to both metagenomic and metatranscriptomics data Knowing the combined genomic potential of a microbial community is proving indispensable for practical applications of translational microbiome science, This cutting edge, accurate, easy and fast functional analysis feature is part of our ongoing mission to provide everything researchers need to complete their end-to-end microbiome analysis and lower the barrier to entry for those interested in the field. - CosmosID CEO, Manoj Dadlani. The updated web application is part of CosmosID's microbial genomics platform, CosmosID-HUB, which is continually expanding with various apps and modules for analyzing microbial communities and for inferring translational and actionable microbiome insights. Currently, CosmosID-HUB: Microbiome provides options for discovering antimicrobial resistance and virulence markers, microbial taxa (composition) and function whereas CosmosID-HUB: COVID-19 is a separate module for detecting the presence of COVID-19 and characterizing variants of concern/interest in both clinical and wastewater specimens. Researchers have the flexibility to access and pay for the type of analysis they require. Soon, CosmosID-HUB will include a revolutionary web application for microbiome multi-dimensional feature testing and multi-omics analysis. In addition to strain-level resolution enabled by its curated databases of over 170,000 genomes and gene sequences, CosmosID® also offers next-generation sequencing services. To date, the company has demonstrated its best-in-class technology and won three different challenges for its detection accuracy, including both PrecisionFDA challenges as well as the Janssen/DNAnexus Mosaic 'Strain' challenge. About CosmosID® CosmosID® provides end-to-end solutions unlocking the microbiome. A provider of CLIA-certified & ICH-GCP compliant NGS Services and Bioinformatics Solutions, CosmosID offers a range of validated and optimized workflows for a range of applications including pharmaceutical R&D, infectious disease diagnostics, environmental testing, microbiome research, animal health, cosmetics & personal care as well as many more.
