Gene Sequences Shed Light on Over One Billion Years of Green Plant Evolution

Technology Networks | October 24, 2019

Gene sequences for more than 1100 plant species have been released by an international consortium of nearly 200 plant scientists who were involved in a nine-year research project, One Thousand Plant Transcriptomes Initiative (1KP), that examined the diversification of plant species, genes and genomes across the more than one-billion-year history of green plants dating back to the ancestors of flowering plants and green algae. Their findings, “One Thousand Plant Transcriptomes and Phylogenomics of Green Plants,” published today in Nature, (doi: 10.1038/s41586-019-1693-2) reveal the timing of whole genome duplications and the origins, expansions and contractions of gene families contributing to fundamental genetic innovations enabling the evolution of green algae, mosses, ferns, conifer trees, flowering plants and all other green plant lineages. The history of how and when plants secured the ability to grow tall, and make seeds, flowers and fruits provides a framework for understanding plant diversity around the planet including annual crops and forest tree species. Sequences, sequence alignments and tree data are available through the CyVerse Data Commons. “Plants have evolved to produce numerous useful chemicals. This study provides insight into that evolutionary process,” said Toni Kutchan, Ph.D., vice president for Research and Oliver M. Langenberg Distinguished Investigator, Donald Danforth Plant Science Center. Megan Augustin, research associate, Alex Harkess, Ph.D., postdoctoral associate and Michael McKain, Ph.D., former postdoctoral associate at the Danforth Center also contributed to the research.

Agricultural policy in Thailand has changed from having rice farming as the only major practice to one that promotes crop diversification and the promotion of field and horticultural crops. This shift can be attributed mainly to the trend towards export commodities.

Terumo Blood and Cell Technologies to Collaborate with CSL Plasma on U.S. FDA Clearance of Plasma Collection Technology

CSL Plasma | March 11, 2022

CSL Plasma, a division of global biotherapeutics pioneer CSL Behring, announced the Rika Plasma Donation System created by Terumo Blood and Cell Technologies, a medical technology company based in Lakewood, Colorado, has received regulatory approval. The new plasmapheresis system is expected to provide technologies to support a safe, efficient, and better experience for plasma donors and an improved experience for CSL Plasma personnel, according to Terumo Blood and Cell Technologies. Additional characteristics of the new Rika system, according to CSL Plasma, will allow for the collection of more plasma in less time, hence improving quality and safety and, in turn, better serving patients who rely on plasma-based therapies. These advantages include: On average, Rika completes one plasma collection in 35 minutes or less: Compared to previous average CSL Plasma donation timings, this might mean a nearly 30% reduction in donor donation time. It assures that no more than 200 milliliters of blood are ever removed from the donor's body. This is believed to make the donor more comfortable during the donation process and lessen the risk of red cell loss deferral. It has a sophisticated user interface that helps CSL Plasma front-line personnel operate the equipment. This milestone helps bring to life how we demonstrate innovation, collaboration, and patient-focus, part of the CSL Values that underpin our commitment to manufacturing and delivering life-saving and life-extending medicines around the world, We continue to evolve as a leading biotechnology company, investing in our core plasma business. Continued innovation that benefits our employees and plasma donors speak to how we are driven by our promise to save and improve lives around the world." CSL Chief Operating Officer Paul McKenzie. CSL Plasma will begin installing the new technology at locations in the Denver, Colorado, area in the following months. There is a critical and ongoing need for human plasma to produce life-saving medicines for people with serious and rare diseases, CSL Plasma's decision to work with Terumo Blood and Cell Technologies is consistent with our business goals to improve the donor and employee experience through innovation and remain the plasma donation center of choice. We look forward to rolling out this new technology." CSL Plasma General Manager Michelle Meyer.

Xalud Therapeutics Completes Oversubscribed $30 Million Series C Financing

Xalud Therapeutics | August 25, 2021

Xalud Therapeutics, a clinical-stage biotechnology company developing novel non-viral gene therapies to treat pathologic inflammation, announced today that it has raised $30 million in a Series C financing. “We are well positioned to continue advancing XT-150, our lead therapeutic candidate, through clinical development and further expand our platform” XT-150 is a locally injectable plasmid DNA gene therapy expressing IL-10v – a proprietary long-acting, modified variant of IL-10 with enhanced durability properties over the naturally occurring wild-type cytokine. XT-150 is currently being evaluated in a Phase 2b study for moderate-to-severe pain caused by osteoarthritis of the knee, a Phase 1/2a study for peripheral neuropathic pain and a study for facet joint syndrome is expected to be initiated by end of year. While serving as milestones along a potential route to approval for each of these indications, the studies also provide valuable safety and efficacy data to guide future clinical development for additional indications currently in the IND-enabling stage. “We are proud to lead Xalud’s Series C financing and continue to support their efforts to build a leading gene therapy company that will address a significant unmet need in the field of chronic inflammatory diseases,” said Paul Manning, chief executive officer and chairman of PBM Capital. “Xalud has assembled an experienced leadership team, supported by diverse and distinguished strategic advisors, who have made strides in progressing their clinical programs and exploring additional indications with large potential.” About Xalud Therapeutics Xalud Therapeutics is a biotechnology company developing a non-viral gene therapy platform to treat pathologic inflammation through immune modulation. The company is harnessing the power of interleukin-10 (IL-10), a potent cytokine that acts as a master regulator for multiple inflammatory pathways, to address the root cause of inflammation and subsequently restore homeostasis in the immune system. Xalud’s lead product candidate, XT-150, is a locally injectable plasmid DNA gene therapy expressing IL-10v, a proprietary modified variant of IL-10, that addresses pathologic inflammation and pain.
