The new system, which has been demonstrated to work in E. coli, might have significant implications for human clinical applications. A significant challenge in synthetic biology is the regulation of gene networks rather than single genes. Traditional methods often struggle to control multiple genes simultaneously due to the complexity and interconnectivity of gene networks. This complexity can result in unpredictable behaviours and reduced efficiency in gene expression control. The precision required to manage multiple genes, especially within metabolic pathways, demands sophisticated tools that can integrate various signals and respond accurately, something that has proven difficult with existing technologies. The concept of logical operations, such as those found in digital electronics, offers a promising solution for the regulation of gene expression. By employing Boolean logic gates (AND, OR, NOT, and their combinations), researchers can create genetic circuits that perform complex decision-making processes based on multiple inputs. Logic gates allow for the conditional regulation of genes, providing a more robust and flexible approach to controlling biological systems. Logical operations enable the integration of diverse signals, facilitating precise control over gene networks and enhancing the ability to fine-tune cellular processes.

𝗖𝗥𝗜𝗦𝗣𝗥 𝗧𝗮𝗿𝗴𝗲𝘁𝘀 𝗣𝗮𝗻𝗰𝗿𝗲𝗮𝘁𝗶𝗰 𝗖𝗮𝗻𝗰𝗲𝗿 𝗠𝘂𝘁𝗮𝘁𝗶𝗼𝗻𝘀 Researchers have developed a selective CRISPR-Cas9 strategy to target somatic mutations in pancreatic cancer cells, which is showing promising results for precision cancer therapy. American researchers at the Johns Hopkins University School of Medicine adapted the CRISPR-Cas9 technology to specifically target somatic mutations that generate protospacer adjacent motifs (PAMs) within pancreatic cancer genomes. Whole genome sequencing of tumours and normal tissues from pancreatic cancer patients revealed numerous somatic PAMs, providing specific targets for CRISPR-induced double-strand breaks (DSBs). This selective targeting method resulted in significant cancer cell death with minimal off-target effects. The CRISPR approach involves the identification and utilisation of single base substitutions that create over 400 novel PAM sequences unique to the cancer cells. Researchers developed a bioinformatics pipeline named PAMfinder to pinpoint these mutations across the cancer genome.

"The 3rd Copenhagen symposium on Advances in T cell therapy and Cellular engineering (CATC)" 24-25 September 2024. DTU, Kgs Lyngby, Denmark The Copenhagen Symposium on T Cell Therapy and Cellular Engineering (CATC) is a key event dedicated to exploring recent advancements in medical science.

𝗖𝗥𝗜𝗦𝗣𝗥 𝗜𝗱𝗲𝗻𝘁𝗶𝗳𝗶𝗲𝘀 𝗡𝗲𝘄 𝗚𝗲𝗻𝗲𝘀 𝗮𝘀 𝗗𝗿𝗶𝘃𝗲𝗿𝘀 𝗼𝗳 𝗣𝗿𝗼𝘀𝘁𝗮𝘁𝗲 𝗖𝗮𝗻𝗰𝗲𝗿 𝗠𝗲𝘁𝗮𝘀𝘁𝗮𝘀𝗶𝘀  Three research groups recently independently elucidated the genetic and epigenetic mechanisms driving prostate cancer metastasis. The innovative use of CRISPR technology not only facilitated the discovery of the genes but also opened potential new avenues for targeted cancer therapies to prevent metastasis. CRISPR Medicine News interviewed Juan Martín Arriaga and Martin Kristian Thomsen who have made significant contributions to understanding the genetic drivers of prostate cancer metastasis using CRISPR technology. Arriaga's research identified CITED2 as a novel driver of bone metastasis in prostate cancer by conducting an in vivo genome-wide CRISPR screen. His team found that overexpressing CITED2 in the prostate led to metastasis, demonstrating its crucial role. Conversely, when CITED2 was inhibited, metastasis was suppressed. Thomsen's approach involved mutating specific tumour suppressor and epigenetic factor genes in a Cas9-positive mouse model, allowing for precise targeting within the prostate. His research revealed that mutations in the gene KMT2C were particularly significant for lung metastasis. We also dive into a third study by Maria Rodrigo-Faus who identified PRMT7 as crucial for prostate cancer metastasis.
