Cholesterol metabolism reprogramming in multiple myeloma: examining its specificity and impact on the immune microenvironment.
Review in American journal of cancer research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Multiple myeloma (MM) represents a malignancy within the hematological system, in which the reprogramming of cholesterol metabolism plays a pivotal role in its pathogenesis. This review focuses on the specificity of cholesterol metabolism abnormalities in the diagnosis of MM and their implications for the immune microenvironment, aiming to provide new perspectives for both diagnosis and treatment of MM. The expression changes of cholesterol metabolism-related genes (CMGs), such as ANXA2 and CHKA, closely correlate with the prognosis of MM. These CMGs are linked not only to clinical parameters, including the number of transplants and the International Staging System, but also to tumor incidence, progression, and treatment resistance. Consequently, they offer new biological markers for both the prognosis assessment and therapeutic strategies for MM. In terms of the immune microenvironment, reprogramming of cholesterol metabolism significantly influences tumor-infiltrating immune cells (TIICs), including T lymphocytes, B lymphocytes, tumor-associated macrophages (TAMs), dendritic cells (DCs), and myeloid-derived suppressor cells (MDSCs). Moreover, the cholesterol metabolite 25-hydroxycholesterol (25-HC) enhances the activity of immunosuppressive macrophages by modulating lysosomal AMPK activation and metabolic reprogramming, thus presenting a new metabolic target for tumor immunotherapy. The regulatory effects of cholesterol metabolism on MDSCs are also noteworthy; these cells promote tumor progression by inhibiting T-cell responses. High-fat diets and obesity can induce the accumulation of MDSCs, where molecules involved in the cholesterol metabolic pathway, such as the synthase CYP27A1 for 27-hydroxycholesterol (27-HC), have been associated with poor prognoses in ovarian cancer. Genetic knockout of this enzyme significantly inhibits tumor progression. Regarding the diagnostic specificity of cholesterol metabolism abnormalities, these changes present novel biomarkers for the early diagnosis and therapeutic monitoring of MM. Analyzing the correlation between immune cell proportions in the tumor microenvironment and lipid metabolism genes has unveiled potential links between cholesterol metabolism and immune responses, paving the way for precision medicine in MM. Thus, the reprogramming of cholesterol metabolism in MM offers a multidimensional and interdisciplinary research avenue. Future studies need to delve deeper into the specific mechanisms through which cholesterol metabolism contributes to MM development and leverage these findings to formulate new therapeutic strategies, ultimately improving outcomes for MM patients.
