Identification of Metastasis-Associated Metabolic Profiles of Tumors by 1H-HR-MAS-MRS

Abstract: Tumors develop an abnormal microenvironment during growth, and similar to the metastatic phenotype, the metabolic phenotype of cancer cells is tightly linked to characteristics of the tumor microenvironment (TME). In this study, we explored relationships between metabolic profile, metastatic propensity, and hypoxia in experimental tumors in an attempt to identify metastasis-associated metabolic profiles. Two human melanoma xenograft lines (A-07, R-18) showing different TMEs were used as cancer models. Metaboli… Show more

“…Consistent with these results, distinct metabolic profiles were revealed between non-metastatic and metastatic cells of human R-18 melanoma cell line (established from a xenograft model) by proton high resolution magic angle spinning magnetic resonance spectroscopy ( 1 H-HR-MAS-MRS) (198). The metastatic tumors expressed higher levels of phosphocholine, creatine, and glycine, while lower levels of lactate were observed.…”

“…The 5-year survival rate is 63% in patients with localized lung cancer, but it decreases to 35% if the cancer spreads to nearby tissue, and drops to approximately 7% if distant metastasis occurs [ 2 ]. Primary tumors and metastases show a variety of metabolic processes that are tightly linked to the characteristics of the tumor microenvironment [ 3 ]. More importantly, based on the various treatment responses of primary, metastatic, or recurrent tumors, understanding the metabolic status of the lesions would be a good means for predicting treatment responses [ 4 ].…”

“…The apparent diffusion coefficient (ADC), measured by DWI, reflects the structural limitation of tissue water molecule Brownian motion and is related to cell density. , The volume transfer constant ( K trans ) obtained from DCE-MR was reported to assess microvascular permeability changes after VEGF inhibitor therapy and informs on prognosis . Meanwhile, MRS, as a noninvasive method for obtaining in vivo biochemical and metabolic information, was shown to assess the hypoxia condition in metastasis via lactate (Lac) measurement .…”
