Metabolic changes in primary tumors can lead to the development of the metastatic phenotype. The objective of this study is to demonstrate the link between LDH-A expression and lactate level in tumors. The LDH-A silenced 4T1 tumors have slower growth rate compare to the control 4T1 tumors. Both nonlocalized- and localized-spectra are acquired using the selective multiple-quantum coherence transfer (SelMQC) sequence in vivo. The LDH-A silenced 4T1 tumors showed a lower level of lactate compare to 4T1 control tumors.
