26.03.2013 - British researchers have found that one single protein seems to control resistance against multiple herbicides of cereal crops weeds.
Multiple-herbicide resistance (MHR) in black-grass and annual rye-grass is a global threat for agriculture, leading to loss of chemical weed control in cereal crops. Until now, it was only poorly understood why MHR is associated with an enhanced ability to detoxify xenobiotics. Assuming an analogy with multiple drug resistance, which occurs in human tumours, researchers from York University and Syngenta now report they have found a possible explanation.
When they searched in black-grass and annual rye-grass for a plant homologue to the MDR causing phi glutathione S transferase (GSTP1) they found an enzyme that also showed both detoxification and signalling. When expressed in Arabidopsis thaliana, the protein termed GSTF1 led to multiple herbicide resistance in the model organism and showed a similar secondary metabolism pattern as the weeds. Those were not associated with a differential gene expression pattern but directly caused by GSTF1.
When they applied the GSTP1 blocker 4-chloro-7-nitro-benzoxadiazole to the weeds, the MHR masterswitch was blocked. They conclude that overexpression of GSTF1 orchestrates multi-herbicide resistance in grass weeds and that targeting the protein is a promising approach to regain weed control in cereal crops.
04.05.2016 Barcelona-based epigenetics expert Oryzon Genomics has closed a debt funding round of €10.5m, bringing the total money raised since last year to €27m. The funds will serve to advance the company’s two LSD1 inhibitors in cancer and neurodegeneration.
03.05.2016 Ipsen is strengthening its ties to long-time development partner Oncodesign, a Dijon-based cancer treatment biotech. The French pharma is handing over the pre-clinical pharmacology for its oncology research programmes to Oncodesign.
29.04.2016 Swiss bank Group UBS has raised US$471m (€412m) for the UBS Oncology Impact Fund, which was set up to invest in early-stage cancer treatments. The money raised by the fund, nearly half of which comes from investors in Asia, is the largest amount ever raised for such a cancer investment fund.
27.04.2016 More revenue, more jobs, more financing, more R&D expenditure – all signs point towards sustainable growth in the German biotech sector. These are the results of the most recent company survey 2016, published by biotechnologie.de. The report was once again conducted alongside the biotech standards defined by the organisation for economic cooperation and development (OECD).
21.04.2016 An expert panel’s final report on the fatal drug trial earlier this year in France states that the death of one of the participants was most likely caused by the drug’s toxicity and not by any violation of the rules.
21.04.2016 For up to US$685m (€606m), Dutch ArgenX has outlicensed its human antibody programme ARGX-115 to AbbVie. The pre-clinical immuno-oncology candidate targets a protein believed to contribute to immunosuppressive effects of T-cells.
19.04.2016 British drug developer Heptares Therapeutics and mAb maker Kymab Ltd have partnered up in yet another immuno-oncology collaboration. The companies plan to discover antibody meds targeting a superfamily of receptors.
15.04.2016 Not every company is put off by the current stock market climate. Swiss biopharma company GeNeuro has gone public at Euronext Paris, raising €33m in the process. Others, meanwhile, have to find different ways to raise money.
13.04.2016 Despite political disturbances, 2015 was a good year for the biotech scene in Switzerland. Net sales increased by 5.1% to CHF5,133m and 400 additional people found jobs in the sector. As usual, the new numbers were presented at the annual Swiss Biotech Day – which set new records as well.
