Core Viewpoint - The article discusses a novel cancer treatment strategy called "Decaging-to-Ligation" (D2L), which enables precise recruitment of proteins or immune cells to tumor sites, significantly inhibiting tumor growth while minimizing systemic toxicity [3][12]. Group 1: Research Findings - The study successfully synthesized proteolysis-targeting chimeras (PROTAC) in tumor-localized concentrations sufficient for effective target protein degradation, leading to a 14.8-fold increase in T cell activation levels [2][10]. - The D2L strategy effectively overcomes On-target Off-tumor (OTOT) toxicity, a major barrier for therapies like PROTAC and T cell-mediated immunotherapy [5][12]. - The research team demonstrated the feasibility of the D2L strategy by achieving selective imaging of FAP-positive cells and successfully degrading the target protein BRD4 in tumors with minimal toxicity to the small intestine [10][12]. Group 2: Technological Innovations - The D2L strategy represents an innovative approach in the intersection of chemical biology and drug discovery, facilitating tumor-selective reactions that can induce proximity effects between proteins and cells [7][12]. - The study highlights the potential of bioorthogonal chemistry in achieving selective drug release at tumor sites, bridging the gap between bioorthogonal connection technology and tumor-selective regulation [6][12]. Group 3: Implications for Cancer Treatment - The D2L strategy is positioned as a promising platform for precise cancer treatment, aiming to activate therapeutic assemblies in vivo and address critical limitations of proximity-mediated cancer therapies [12].

Core Viewpoint - The article discusses the potential winners of the Nobel Prize in Physiology or Medicine, focusing on the significance of scientific discoveries and their applications in the medical field, particularly highlighting the discovery of GLP-1 as a strong candidate for the award in 2025 [1][3]. Group 1: Historical Context and Trends - The Nobel Prize in Physiology or Medicine has historically awarded discoveries that are significant in both scientific and practical applications, with a distribution ratio of approximately 3:2 between physiology and medicine since 2001 [1][2]. - The awarding pattern shows a tendency to recognize impactful medical discoveries every few years, with the last notable award in the metabolic research area occurring 40 years ago [6][7]. Group 2: GLP-1 Discovery - The discovery of GLP-1 is considered a major breakthrough in metabolic regulation, with an 85% probability of winning the Nobel Prize due to its significant scientific and practical implications [3][4]. - GLP-1-based drugs, such as semaglutide and tirzepatide, are projected to rank among the top ten global drug sales in 2024, showcasing their widespread application and importance in treating obesity [4][5]. - The recognition of GLP-1's importance has grown in recent years, and it has been a contender for major scientific awards, indicating its readiness for Nobel recognition [6][7]. Group 3: Potential Awardees - Key contributors to the discovery of GLP-1 include Jens Juul Holst and Joel Habener, both with a 100% probability of winning due to their foundational work in identifying and characterizing GLP-1 [8][10]. - Svetlana Mojsov, another significant contributor, has a 75% probability of winning, while Daniel Joshua Drucker and Lotte Knudsen have lower probabilities of 20% and 5%, respectively, due to their roles being more focused on later developments rather than the initial discovery [12][15][17]. Group 4: Other Potential Projects - Other projects, such as the development of fMRI and PET technologies, have a lower probability of winning (15%) due to their perceived lack of groundbreaking discovery elements compared to GLP-1 [19][21]. - Additional medical achievements, including Herceptin and Gleevec, are noted for their clinical significance but are considered less competitive against GLP-1 [22][23]. - Basic research achievements in physiology are deemed unlikely to win, with a probability of less than 1% due to the vast number of contributions in this area [24].
