Article Abstract
Metabolic rewiring/reprogramming is an essential hallmark of cancer. Alteration of metabolic phenotypes is occurred in cancer cells in response to a harsh condition to support cancer cell proliferation, survival, and metastasis. Stable isotope can be used as a tracer to investigate the redistribution of the carbons labeled in glucose in order to elucidate the detailed mechanisms of cellular rewiring and reprogramming in tumor microenvironment. Stable isotope-resolved metabolomics (SIRM) is an analytical method inferring metabolic networking by using advanced nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) to analyze the fate of a single atom from a stable isotope-enriched precursor to a product metabolite. This methodology has been demonstrated for a wide range of biological applications, including cancer metabolomic analysis. The basic principle and platforms of SIRM and its implication for cancer metabolism research will be addressed in this chapter.

Small cell lung cancer (SCLC) is a highly aggressive type of lung cancer, characterized by rapid proliferation, early metastatic spread, frequent early relapse and a high mortality rate. Recent evidence has suggested that innervation has an important role in the development and progression of several types of cancer. Cancer-to-neuron synapses have been reported in gliomas, but whether peripheral tumours can form such structures is unknown.

Chronic restraint stress (CRS) is a widely recognized model to study stress-induced anorexia and metabolic dysregulation in mice. Acyl-coenzyme A-binding protein (ACBP) has emerged as a critical player in metabolic regulation, with potential implications for stress-related disorders. This study presents two complementary methodologies to artificially elevate circulating Acyl-CoA-binding protein (ACBP) levels in mice under CRS.

Cystic fibrosis (CF) is a genetic disorder primarily known for its severe impact on lung function, but it also significantly affects the digestive system, leading to complications such as intestinal blockages, malabsorption, inflammation, and microbial dysbiosis. The study of CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) effects on intestinal physiology is critical for developing new effective treatments. This work highlights the use of the mouse intestine as a valuable model for analyzing cellular electrophysiology and CFTR function.

Head and neck squamous cell carcinoma (HNSCC) is among the most prevalent human malignancies globally, with approximately 887,000 new cases diagnosed each year. Currently, the standard treatment for HNSCC involves surgery, followed by radiotherapy, chemotherapy and immunotherapy. However, despite these available treatments, the survival rate of patients with HNSCC remains low.

Cushing's syndrome is caused by chronic exposure to excessive levels of glucocorticoids. It is characterized by significant phenotypic alterations including increased visceral adiposity and fat deposits on the cheeks, leading to a characteristic 'moon face' appearance. Although glucocorticoid therapy is widespread, its associated side effects are of significant clinical concern.
