Radiotherapy-induced DNA damage can lead to apoptotic cell death and trigger an anti-tumor immune response via the cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway, which senses cytoplasmic double-stranded DNA. However, radiotherapy resistance poses a significant challenge in treating cancers, including colorectal cancer (CRC). Understanding the mechanisms underlying this resistance is crucial for developing effective therapies.

The efficient generation of circularly polarized light (CPL) is crucial in information technologies such as optical communications and three-dimensional displays. In nature, many plants and animals can transform unpolarized light into CPL with chiral helical superstructures, which has inspired the development of CPL-related materials and devices. Herein, by combining the self-assembled chiral nematic liquid crystalline microstructures of cellulose nanocrystals with geometrical configurations of Fresnel lenses, free-standing solid-state cellulosic converging lenses with large sizes, circular polarization features, and adjustable chiral photonic bandgaps were fabricated at low cost, which could produce CPL beams exhibiting dissymmetry factors ( = 2( - )/( + )) up to -0.

Gravity of the Earth (g) drives the macroscopic differentiation of multiple phases with different volumetric mass densities in many chemical and physical processes. Herein, liquid crystalline phase separation of colloidal dispersions of rod-shaped cellulose nanoparticles in centrifugal acceleration fields up to 71 061 meters per second squared (7251 g) is studied. Through non-ionic in situ free-radical polymerization initiated by time-controllable oxidation-reduction reactions between tert-butyl hydroperoxide (oxidants) and thiourea (thiocarbamide, reductants) at room temperature (298 kelvins), ordered soft microstructures formed by entropy-driven self-assembly are immobilized within crosslinked polyacrylamide matrixes at various evolution stages (e.

Herein, an imidazo-pyridin-derived fluorescent probe ImPy-HS was developed for monitoring the hydrogen sulfide (HS) level in the water decoction of Chinese medicinal materials. Under the excitation at 355 nm, ImPy-HS exhibited the obvious fluorescence response at 490 nm. The detection system with ImPy-HS showed the advantages including relatively high sensitivity, high selectivity, and high steadiness.

Thermogenic fat, including brown and beige fat, dissipates heat via thermogenesis and enhances energy expenditure. Thus, its activation represents a therapeutic strategy to combat obesity. Here, we demonstrate that levels of F-box and WD repeat domain-containing 7 (FBXW7), an E3 ubiquitin protein ligase, negatively correlate with thermogenic fat functionality.

Muscular atrophy is among the systematic decline in organ functions in aging, while defective thermogenic fat functionality precedes these anomalies. The potential crosstalk between adipose tissue and muscle during aging is poorly understood. In this study, it is showed that UCP1 knockout (KO) mice characterized deteriorated brown adipose tissue (BAT) function in aging, yet their glucose homeostasis is sustained and energy expenditure is increased, possibly compensated by improved inguinal adipose tissue (iWAT) and muscle functionality compared to age-matched WT mice.

Tumor-associated macrophages (TAMs), a crucial component of the tumor microenvironment (TME), are closely associated to the growth, invasion, metastasis, and prognosis of breast cancer. Targeting TAMs is considered to be a potential new strategy for improving the therapeutic efficacy of breast cancer. TAMs interact with breast cancer cells and influence the development and progression of various breast cancer subtypes through multiple pathways, including the secretion of proteins, cytokines, chemokines, and exosomes.

Cholesterol metabolism is vital for multiple cancer progression, while how cholesterol affects lung, a low-cholesterol tissue, for cancer metastasis and the underlying mechanism remain unclear. In this study, we found that metastatic lung adenocarcinoma cells acquire cellular dehydrocholesterol and cholesterol by endogenous cholesterol biosynthesis, instead of uptake upon cholesterol treatment. Besides, we demonstrated that exogenous cholesterol functions as signaling molecule to induce FOXA3, a key transcription factor for lipid metabolism via GLI2.
