“Cancers are characterized not only by major changes in their genomes, but also by profound shifts in how they take up and utilize nutrients to propel rapid tumor growth,” said senior author Paul S. Mischel, MD, professor in the UC San Diego School of Medicine Department of Pathology and Ludwig member. “How do these diverse aspects fit together and can they be taken advantage of, for the benefit of patients?”
‘DNA sequencing technology helped to understand the molecular basis of cancer, which further aids to identify a new and more effective way of treating cancer patients.’
Without LPCAT1, tumors cannot survive. When researchers genetically depleted LPCAT1 in multiple types of cancer in mice, including highly lethal glioblastomas (brain) and an aggressive lung cancer, malignancies shrank dramatically and survival times improved.
The results, wrote the authors, demonstrate that LPCAT1 is an important enzyme that becomes dysregulated in cancer, linking common genetic alterations in tumors with changes in their metabolism to drive aggressive tumor growth.”
“Advances in DNA sequencing technologies have reshaped our understanding of the molecular basis of cancer, suggesting a new and more effective way of treating cancer patients,” said Mischel. “However, to date, precision oncology has yet to benefit many patients, motivating a deeper search into understanding how genetic alterations in tumors change the way cancer cells behave, and potentially unlocking new ways to more effectively treat patients.
“These results also suggest that LPCAT1 may be a very compelling new drug target in a wide variety of cancer types.”
