Tumor cells divide rapidly and dramatically alter their metabolism to meet biosynthetic and bioenergetic needs. Through studying the aberrant metabolism of cancer cells, other contexts in which metabolism drives cell state transitions become apparent. In this work, we will discuss how principles established by the field of cancer metabolism have led to discoveries in the contexts of physiology and tissue injury, mammalian embryonic development, and virus infection. We present specific examples of findings from each of these fields that have been shaped by the study of cancer metabolism. We also discuss the next important scientific questions facing these subject areas collectively. Altogether, these examples demonstrate that the study of "cancer metabolism" is indeed the study of cell metabolism in the context of a tumor, and undoubtedly discoveries from each of the fields discussed here will continue to build on each other in the future.

Background: Real-time reverse transcription quantitative polymerase chain reaction (RT-qPCR) is a powerful tool for analysing target gene expression in biological samples. To achieve reliable results by RT-qPCR, the most stable reference genes must be selected for proper data normalisation, particularly when comparing cells of different types. We aimed to choose the least variable candidate reference genes among eight housekeeping genes tested within a set of human cancer cell lines (HeLa, MCF-7, SK-UT-1B, A549, A431, SK-BR-3), as well as four lines of normal, non-malignant mesenchymal stromal cells (MSCs) of different origins.

Background: Endometriosis patients exhibit a cancer-like glycolytic phenotype. The pyruvate kinase M2 (PKM2)/hypoxia-inducible factor-1 alpha (HIF-1α) axis plays important roles in glycolysis-related diseases, but its role in patients with endometrial polyps (EPs) combined with endometriosis has not been validated.
Methods: EP samples were collected from patients with and without endometriosis.

The Warburg effect, also known as 'aerobic' glycolysis, describes the preference of cancer cells to favor glycolysis over oxidative phosphorylation for energy (adenosine triphosphate-ATP) production, despite having high amounts of oxygen and fully active mitochondria, a phenomenon first identified by Otto Warburg. This metabolic pathway is traditionally viewed as a hallmark of cancer, supporting rapid growth and proliferation by supplying energy and biosynthetic precursors. However, emerging research indicates that the Warburg effect is not just a strategy for cancer cells to proliferate at higher rates compared to normal cells; thus, it should not be considered an 'enemy' since it also plays complex roles in normal cellular functions and/or under stress conditions, prompting a reconsideration of its purely detrimental characterization.

Objective: The current study aimed to develop an experimental approach for the direct co-culture of three-dimensional breast cancer cells using single-cell RNA sequencing (scRNA-seq).
Methods: The following four cell culture groups were established in the Matrigel matrix: the untreated Michigan Cancer Foundation (MCF)-7 cell culture group, the MCF-7 cell culture plus cisplatin group, the untreated co-culture group, and the cell co-culture plus cisplatin group. For cell co-culture, MCF-7 cells, human mammary fibroblasts, and human umbilical vein endothelial cells were mixed at a ratio of 1:1:1.

Background: Aneuploidy is crucial yet under-explored in cancer pathogenesis. Specifically, the involvement of brain expressed X-linked gene 4 () in microtubule formation has been identified as a potential aneuploidy mechanism. Nevertheless, 's comprehensive impact on aneuploidy incidence across different cancer types remains unexplored.
