Colorectal cancer (CRC) remains one of the most common malignancies worldwide with relatively high levels of morbidity and mortality. Current data demonstrate the significant role of adipokines, in particular leptin and adiponectin, in CRC pathogenesis and progression. Both adipokines exert pleiotropic activities and often possess opposing physiological effects. The main goal of this study was to provide a comprehensive overview of current knowledge regarding the complex relationship between leptin and adiponectin signaling and tumorigenesis with a specific focus on CRC. The pro-tumorigenic role of leptin in CRC has been highly emphasized by recent reports, primarily by activation of JAK2/STAT3 and PI3K/Akt/mTOR signaling pathways. In contrast, adiponectin has been shown to demonstrate an anti-tumorigenic role mainly because of activation of AMPK and PPARα signaling cascades. Focusing on the current advances in the field of adipokines’ signaling, we highlighted the latest achievements in understanding their role in colorectal malignancy.

Dysregulation in miRNA expression has been reported in a variety of tumors, including colorectal cancer (CRC), where adiponectin regulates a number of processes related to tumorigenesis. The aim of this study was to identify a panel of heavily and consistently altered miRNAs in CRC that affect adiponectin signaling based on bioinformatics analysis and cross-referencing the available literature. Bioinformatics tools were used to analyze publicly available datasets to identify miRNAs targeting the adiponectin pathway that are substantially dysregulated in CRC. In parallel, a comprehensive literature review was conducted to gather and explore existing knowledge on the relationship between CRC, adiponectin signaling, and miRNA dysregulation. Bioinformatics analysis revealed a set of miRNAs that target adiponectin signaling and are consistently altered in CRC. Several candidate miRNAs, including miR-215-5p, miR-340-5p, miR-181a-5p, miR-150-5p, miR-96-5p, miR-19a-3p, and miR-21-5p, were identified as potential key regulators of the adiponectin cascade, while also being systemically dysregulated in CRC. Through gene ontology enrichment analysis, we further elucidated the biological processes and pathways impacted by these miRNAs, providing insight into their contributions to CRC. The literature review did not identify any previously reported shared connection between these miRNAs, adiponectin signaling, and CRC pathogenesis.

A complex evaluation of colorectal cancer (CRC) in relation to screening, diagnosis, stage determination, prognosis, and treatment requires valuable biomarkers. The aim of this study was to measure selected biomarkers—uric acid (UA), lactate, Na⁺, Cl⁻, and osmolality—in CRC patients and to assess their diagnostic value to distinguish between CRC and healthy controls. Plasma lactate (2.21 ± 0.11 vs. 2.88 ± 0.19, p < 0.01), Na⁺ (130.79 ± 0.42 vs. 133.23 ± 0.25, p < 0.001), Cl⁻ (102.59 ± 0.45 vs. 103.94 ± 0.23, p < 0.01), and osmolality (266.44 ± 0.86 vs. 271.72 ± 0.62, p < 0.001) were found to be significantly lower in CRC patients as compared to the healthy controls group. Among them, with satisfactory diagnostic potential, were plasma Na⁺ concentrations and osmolality (AUCNa+ = 0.752, p < 0.0001; AUCosmolality = 0.757, p < 0.05), respectively. UA concentrations were detected at higher concentrations in CRC patients (333.67 ± 13.05 vs. 295.88 ± 13.78, p < 0.05). The results of this study contribute to the elucidation of molecular mechanisms of CRC pathogenesis and the role of studied metabolic parameters in this process. Plasma uric acid, lactate, and osmolality parameters can be used for screening and monitoring colorectal cancer. Further studies are required to elucidate the molecular mechanisms of their action in cancer development. The action of circulating plasma lactate may be different from those locally produced in the tumor microenvironment.

Background: Leptin and adiponectin play a key role in obesity-associated malignancy, particularly in colorectal cancer (CRC). Immunohistochemical (IHC) evaluation of these adipokines may offer valuable prognostic insights in CRC. This study aimed to analyze global publication trends and summarize current knowledge on the potential of these hormones as IHC biomarkers in CRC. Methods: A problem-oriented bibliometric analysis, including publications from 2000 to 2025 was performed across MEDLINE and Scopus databases. In parallel, a literature review was conducted to present the biological and clinical relevance of these adipokines in CRC. Results and Discussion: A total of 101 publications were identified. Scopus indexed substantially more studies than MEDLINE. The journals Cancer Research, Journal of BUON, Cells, BMC Cancer, and Asian Pacific Journal of Cancer Prevention were identified as the core journals publishing on this topic over the 25-year period. Leading countries were China and USA. A review of the literature showed that adiponectin is a promising prognostic marker, while leptin appears to be a better indicator of disease progression. Conclusions: IHC research on leptin and adiponectin in CRC is a promising but still underexplored area. Their integration with routine molecular assessment has the potential to improve patient stratification.
