Researchers at the Dana-Farber Cancer Institute have been able to identify proteins that were released from muscles during exercise in relatively small quantities. Using their method, the team was able to demonstrate that the neurotrophic factor prosaposin was produced during exercise. Prosaposin is “a well-known CNS neurotrophic factor, but has never been seen to come out of muscle or fat,” Bruce Spiegelman told BioWorld. Spiegelman is a researcher at the Dana-Farber Cancer Institute and Stanley J. Korsmeyer Professor of Cell Biology and Medicine at Harvard Medical School.

Alzheimer’s disease has a higher incidence in women. This sex difference was associated with a modification of certain proteins of the immune system. According to a recent study, the drop in estrogen with menopause increased the expression in the brain of a neurotransmitter, nitric oxide (NO), generating the S-nitrosylation of complement factor C3 (abbreviated SNO-C3), which activated the microglia.

Protein profiling startup Nomic Bio has secured $17 million in an oversubscribed series A financing led by Lux Capital. The funds will be used to expand the company’s servicing and manufacturing labs in Montreal and Boston, to broaden access to its proteomic platform by scaling profiling capacity to 100,000 samples per quarter starting in the second quarter of 2022 and by scaling its protein-detection method, called nELISA, to 500 on-boarded proteins.

Isoplexis Corp. has debuted on the Nasdaq, pricing its initial public offering of 8.3 million common shares at $15.00 per share. Shares of the proteomics platform developer (NASDAQ:ISO) were trading slightly under at $13 following the listing. The offering is expected to close on Oct. 12, 2021. The Branford, Conn.-based company is aiming to raise $125 million from the public market to accelerate commercialization of its cell analysis platforms. The single-cell proteomics systems are automated, benchtop products designed to reduce therapeutic development timelines.

Prophet, Oncohost Ltd.’s artificial intelligence-driven proteomics profiling platform, predicted response to immune checkpoint inhibitor (ICI) therapy in non-small-cell lung carcinoma (NSCLC) patients in a study presented at the European Society for Medical Oncology Virtual Congress 2021. While ICI can generate a significant positive response in some patients with advanced NSCLC, in others the therapy promotes tumor growth, making identification of likely responders prior to treatment critical.

Intervenn Biosciences raised $201 million in a series C financing led by new investors Softbank Group, Heritage Provider Network, Irving Investors and Highside Capital Management. The proceeds are earmarked to speed development and commercialization of Dawn, a liquid biopsy assay for immune checkpoint inhibitor prediction, and to expand the network of partnerships on the company’s artificial intelligence (AI)-driven glycoproteomics platform.

Oncohost Ltd. has opened eight U.K. trial sites in the study assessing the ability of its artificial intelligence (AI)-driven proteomics profiling technology to single out which cancer patients will respond to treatment with immune checkpoint inhibitors. The sites will carry out proteomic analyses of blood samples from patients with late-stage melanoma or non-small-cell lung cancer (NSCLC), to predict their likely response to immunotherapy.

Somalogic Inc. has agreed to go public via a merger with blank-check company CM Life Sciences II. Upon closing, CMLS II – a special purpose acquisition company (SPAC) sponsored by affiliates of Casdin Capital LLC and Corvex Management LP – will be renamed Somalogic and its common stock listed on the Nasdaq Global Market under the ticker symbol SLGC.

New funding to the tune of $8 million in series B investment moves Oncohost Ltd. a good bit closer to bringing its personalized immunotherapy prediction platform to market and key operations to the U.S.

New funding to the tune of $8 million in series B investment moves Oncohost Ltd. a good bit closer to bringing its personalized immunotherapy prediction platform to market and key operations to the U.S. Ourcrowd, an investment platform that simplifies investment by accredited investors and others in startups, early-stage companies and venture funds, led the round. Other participants included a group of family offices and private investors.
