Most cancer deaths are due to tumor metastasis rather than the primary tumor. Metastasis is a highly complex and dynamic process that requires orchestration of signaling between the tumor, its local environment, distant tissue sites, and immune system. Animal models of cancer metastasis provide the necessary systemic environment but lack control over factors that regulate cancer progression and often do not recapitulate the properties of human cancers. Bioengineered "organs-on-a-chip" that incorporate the primary tumor, metastatic tissue targets, and microfluidic perfusion are now emerging as quantitative human models of tumor metastasis. The ability of these systems to model tumor metastasis in individualized, patient-specific settings makes them uniquely suitable for studies of cancer biology and developmental testing of new treatments. In this review, we focus on human multi-organ platforms that incorporate circulating and tissue-resident immune cells in studies of tumor metastasis.

Colorectal cancer ranks among the most prevalent and lethal malignant tumors globally. Historically, the incidence of colorectal cancer in China has been lower than that in developed European and American countries; however, recent trends indicate a rising incidence due to changes in dietary patterns and lifestyle. Lipids serve critical roles in human physiology, such as energy provision, cell membrane formation, signaling molecule function, and hormone synthesis.

Various cancer therapeutic strategies have been designed for targeting tumor-associated macrophages (TAMs), but TAM reprogramming-based monotherapy is often clinically hindered, likely due to the lack of a coordinated platform to initiate T cell-mediated immunity. Herein, we fabricated reactive oxygen species (ROS)-responsive human serum albumin (HSA)-based nanoparticles (PEG/IL12-IA NPs) consisting of indocyanine green (ICG), arginine (Arg), and interleukin 12 (IL12). Upon laser irradiation, the nanoparticles were found to be able to dissociate, thus facilitating the release of IL12.

Objectives: To investigate the antitumor effects of aucubin (AC) in non-small cell lung cancer (NSCLC) and uncover its plausible mechanism against lung cancer stem-like cells (LCSCs).
Methods: In vitro experiments included MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, a reagent commonly used for cell viability assay) and colony formation assays to assess anti-proliferative effects on A549 and NCI-H1975 lung cancer cell lines, wound healing and Transwell invasion assays to evaluate inhibition of cell migration and invasion, tumorsphere-formation experiments to detect changes in NSCLC cell stemness, as well as Western blot and quantitative reverse transcription polymerase chain reaction (qRT-PCR) analyses to measure the expression of LCSC markers (CD44, CD133, Oct4, and Nanog). In vivo experiments were conducted to observe the impact of AC on NSCLC metastasis and mouse survival rates.

Post-translational modifications (PTMs) are chemical modifications that occur on specific amino acid residues after protein biosynthesis, which can affect protein function by altering protein structure, localization and activity, thus expanding protein diversity. Extensive research has demonstrated that PTMs can regulate various metabolic processes, such as glucose and lipid metabolism, as well as immune modulation in tumor cells, thereby promoting tumor initiation, progression, and metastasis. In this article, we systematically review a class of emerging PTMs whose roles in tumor metabolism and immune regulation have gradually been recognized in recent years, including six types: lactylation, palmitoylation, SUMOylation, succinylation, crotonylation, and myristoylation.

Given the limited diagnostic technologies and treatment options available for lung adenocarcinoma (LUAD) patients with liver metastases, it is crucial to identify potential genomic signatures associated with liver metastasis, which could significantly contribute to the development of improved diagnostic tools and treatment strategies for LUAD patients with liver metastases. In this study, we identified specific genetic alterations in tumor samples with liver metastases by targeted capture sequencing. The results showed that the significantly higher mutation frequencies of , and in LUAD patients with liver metastases and and mutations found in both tumor tissues and plasma samples from patients with liver metastases.
