Researchers at the National Institutes of Health (NIH) and their collaborators have discovered a new way in which RAS genes, which are commonly mutated in cancer, may drive tumor growth beyond their well-known role in signaling at the cell surface. Mutant RAS, they found, helps to kick off a series of events involving the transport of specific nuclear proteins that lead to uncontrolled tumor growth, according to a study published November 11, 2024, in Nature Cancer.
First author on the QUT-led, multinational study published in Nature Communications, Brisbane’s Translational Research Institute-based Dr Srilakshmi Srinivasan, from QUT’s School of Biomedical Sciences, said the researchers studied the role of a particular prostate cancer genetic variation or SNP.
Gene fusions are vital biomarkers for tumor diagnosis and drug development, with precise detection becoming increasingly important. This review explores the links between gene fusions and common tumors, systematically evaluating detection technologies like fluorescence in situ hybridization (FISH), polymerase chain reaction (PCR), immunohistochemistry (IHC), electrochemiluminescence (ECL), and next-generation sequencing (NGS). FISH is the gold standard for DNA-level rearrangements, while PCR and NGS are widely used, with PCR confirming known fusions and NGS offering comprehensive genome-wide detection. Bioinformatic tools like STAR-Fusion, FusionCatcher, and Arriba are assessed for diagnostic accuracy. The review highlights how artificial intelligence (AI), particularly deep learning (DL) technologies like convolutional neural networks (CNNs) and recurrent neural networks (RNNs), is transforming gene fusion research by accurately detecting and annotating genes from genomic data, eliminating biases. Finally, we present an overview of advanced technologies for gene fusion analysis, emphasizing their potential to uncover unknown gene fusions.
The largest ever clinical trial of T cell therapy (a type of cell-based immunotherapy) for solid tumours has been completed.
Led by a Singapore clinician-investigator, the global, international, multisite trial recruited 330 advanced nasopharyngeal (NPC) cancer patients in 23 sites across Singapore, Malaysia, Thailand, Taiwan and the United States.
The trial did not show an overall survival benefit for the entire patient cohort but a subset analysis combining outcomes of US, Singapore and Taiwanese sites, showed better progression free survival and overall survival.
Results suggest that T cell therapy success would be enhanced by identifying the biomarkers in patients and within the cell therapy, to guide precision delivery.
In a study led by researchers at the NUS Yong Loo Lin School of Medicine, extracellular vesicles (EVs) loaded with customisable anti-cancer antisense oligonucleotides suppressed cancer growth.
A Cancer Research UK-funded trial is giving participants resveratrol as a potential prevention drug for bowel cancer. Resveratrol is a chemical mostly found in red grapes and products made from these grapes, such as wine and juice. Previous lab studies have shown that low doses of purified resveratrol can reach the bowel undigested and inhibit bowel cancer growth.
