Summary: Cooperative interactions in bistable biological regulatory systems can buffer system variability and hinder noise-induced regime shifts. Statistical early warning signals from distributional data can generically detect impending regime shifts. A generic framework based on minimal models can extract robustness and variability properties of more complex models and empirical data close to criticality.

Summary: This passage discusses the mechanical mechanisms of cell volume regulation in a 3D microenvironment, revealing a competitive relationship between intracellular cortices and 3D ECM, as well as the joint regulation of cell growth and volume adaption by factors such as initial cell size and ECM stiffness. It also highlights the critical role of prestresses on cell-ECM interfaces in constraining 3D cell growth, and the geometric size-dependent sensitivity of cell volume variation to external stimuli.

Summary: Animal appendages are used to dissipate excess body heat, with larger appendages facilitating more efficient heat exchange in warmer climates. Endotherms exhibit widespread evidence of 'shape-shifting' in response to climate change. Temperature is a strong predictor of morphological change independently or in combination with other environmental changes.

Summary: Cell-cycle progression and division in animal cells are regulated not only by biochemical factors, but also by mechanical interactions with the microenvironment. This review summarizes recent research on how cells interpret physical cues to promote cell-cycle progression and initiate cell division, as well as how dividing cells generate forces to successfully divide. Additionally, it discusses the potential contribution of force generation during division to larger tissue-scale processes involved in development and homeostasis.

Summary: Catalase is a crucial enzyme in eukaryotic antioxidant systems, and it plays a significant role in plant growth and defense processes. The activity, ligand binding, stability, compartmentation, and function of CAT proteins can be modified by various post-translational modifications. The CAT interactome involves interactions with many cytosolic and nuclear proteins, extending its roles beyond peroxisomal metabolism. Pathogen effector proteins and nucleoredoxin are involved in the nuclear trafficking and activation of CAT in the cytosol and nucleus.

Summary: Cell polarization, crucial in dynamic cellular processes, is precisely controlled by interactions between the nucleus and microtubule organizing center, involving cellular adhesion to extracellular matrix and nucleus-cytoskeletal connections. The localization of individual adhesive spots is more influential than cell shape in inducing intracellular polarization, with disruption of nuclear lamin A/C significantly reducing cell polarization. Geometrical cues guide intracellular polarization, determining directional cell migration through local activation of Cdc42.

Summary: This study investigates the influence of chiral morphologies of helical nanofibers on the fracture properties of biological materials, establishing a crack-bridging model and using a cohesive interfacial model. The research reveals an optimal helical angle for maximizing toughness and provides a scaling law to predict macroscopic fracture toughness of helical fiber-reinforced nanocomposites. It not only sheds light on toughening mechanisms of biological materials, but also offers inspirations for the design and optimization of advanced composites.

Summary: Collective polarization of carcinoma cells is predominantly controlled by the Golgi apparatus, which sustains membrane protrusion formation, polarized secretion, intracellular trafficking, and F-actin polarization. Disruption of the Golgi apparatus results in the destruction of collective polarization over a large scale, highlighting its crucial role in collective cancer cell invasion.

Summary: In the past 30 years, various nano-sized drug delivery systems (nanoDDSs) have been extensively studied for cancer therapy. They can passively target tumors and have enhanced permeability and retention effect. However, their systemic administration has led to complications such as insufficient tumor targeting, undesirable biodistribution, and carrier-associated toxicity. This review summarizes recent advancements in intratumoral nanoDDS administration, discussing factors that enhance therapeutic efficacy and the application in various cancer therapies. Intratumoral administration of nanoDDSs has shown versatility in enhancing tumor-specific accumulation and minimizing side effects, making it a potential solution to improve therapeutic effects and reduce toxicities.
