Abstract

The study of osteoblast (OB) metabolism has recently received increased attention due to the considerable amount of energy used during the bone remodeling process. In addition to glucose, the main nutrient for the osteoblast lineages, recent data highlight the importance of amino acid and fatty acid metabolism in providing the fuel necessary for the proper functioning of OBs. Among the amino acids, it has been reported that OBs are largely dependent on glutamine (Gln) for their differentiation and activity. In this review, we describe the main metabolic pathways governing OBs’ fate and functions, both in physiological and pathological malignant conditions. In particular, we focus on multiple myeloma (MM) bone disease, which is characterized by a severe imbalance in OB differentiation due to the presence of malignant plasma cells into the bone microenvironment. Here, we describe the most important metabolic alterations involved in the inhibition of OB formation and activity in MM patients.

  • Cancer cells primarily use glucose, fatty acids, and amino acids to meet their biosynthetic needs.

    “In other words, cancer cells primarily use glucose, fatty acids, and amino acids to meet their biosynthetic needs [49–52].”

    From Mesenchymal stromal cells in bone marrow niche of patients with multiple myeloma: a double-edged sword (2025) · cites this paper as [49]

    Section 5.3 says glucose and glutamine are two main nutrients cancer cells use for energy, and Section 4.1 links tumor-cell glucose metabolism to production of molecules needed for cell division. The paper’s fatty-acid discussion in Section 4.2 concerns osteoblasts, not cancer cells; it does not support the claim that cancer cells primarily use fatty acids for biosynthesis.

  • Osteoblasts and progenitors use different amino acids such as proline, methionine, arginine and tryptophan in their metabolism to support anabolic functions during bone formation and mineralization.

    “Many studies have shown that OBs and progenitors use different amino acids such as proline, methionine, arginine and tryptophan in their metabolism to support anabolic functions during bone formation and mineralization [49].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
