Researchers continue to search for how they can inhibit cancer metastasis as it can severely worsen prognosis, even if the primary tumor responded well to therapy. Researchers at Università degli Studi di Torino and collaborators previously showed that injecting an RNA aptamer targeting the miRNA miR-214, called anti-miR-214 sponge, reduced metastasis of tumors to lungs and liver. One drawback of this potential therapeutic approach was that the inhibitor oligo could enter all cells, not only tumors.
Triple-negative breast cancer (TNBC) accounts for a substantial proportion of all breast cancers and is the most aggressive form of the disease. Identifying potential therapeutic targets is critical because the cancer does not express the three surface receptors recognized by current targeted therapies.
Proteinqure Inc. has received regulatory clearances from the U.FDA and Health Canada to initiate a phase I trial of lead candidate, PQ-203. The trial will begin in Canada and expand to U.S. sites later in 2025. The FDA also granted PQ-203 fast track designation for triple-negative breast cancer (TNBC).
Characteristics of the tumor microenvironment are likely to contribute to the aggressiveness of triple-negative breast cancer (TNBC) and the extremely poor prognosis of those who suffer it. By analyzing patterns of gene expression in cancer-associated fibroblasts from TNBC tumors, researchers in China identified the PLAU gene as a driver of aggressive phenotype.
With more-than-satisfying phase III data in hand, Minneapolis-based Celcuity Inc. is eyeing an NDA submission in the fourth quarter of this year for gedatolisib (geda) in breast cancer. Shares of the company (NASDAQ:CELC) closed July 28 at $36.79, up $23.02, or 167%, after Wall Street learned of stellar top-line results from the PIK3CA wild-type cohort of the phase III Viktoria-1 trial.
The sialyltransferase ST6GAL1 is upregulated in several types of cancer and its expression is particularly elevated in triple-negative breast cancer, which is extremely aggressive and associated with very poor prognosis.
Current treatments for Alzheimer’s disease have limited effects. While they can slow cognitive decline or alleviate symptoms, they do not reverse this complex neurodegenerative condition caused by multiple factors. Researchers from the Gladstone Institutes and the University of California, San Francisco (UCSF) have screened FDA-approved drugs in search of agents that could potentially modify the disease.
Plexāā Ltd. recently raised $4.5 million to support the upcoming U.S. launch of Bloom43, its wearable device that helps patients prepare for breast cancer surgery and reconstruction by using a technique called supraphysiological preconditioning.
In the current landscape of cancer research, much attention is focused on the tumor microenvironment (TME) at both the primary site and established metastases. However, the early micrometastatic niche remains poorly understood. Researchers from the Hospital del Mar Research Institute (HMRI) have pinpointed T cell immunoglobulin and mucin domain 3 (TIM3) as a key vulnerability in tumor micrometastasis, revealing a new target to halt metastatic progression at its origin.
Dysfunction of the tumor suppressor p53, commonly resulting from MDM2 overexpression or gene mutations, plays a key role in breast cancer progression. While the bioactive compound piperine has been shown to enhance p53 activity, its clinical utility is limited by poor bioavailability, potential toxicity and the risk of adverse drug interactions.
