Background: Clear cell sarcoma (CCS) is a very rare disease and one with a very poor prognosis. Furthermore, its occurrence in the heart is very rare and past reports are scarce.
Case Summary: A 33-year-old man who had undergone left arm amputation due to CCS came to the hospital because a positron emission tomography computed tomography (PET-CT) four years post-amputation showed an accumulation in the heart. The PET-CT with glucose suppression treatment showed fluorodeoxyglucose accumulation in the myocardium between the middle of the anterolateral wall and the papillary muscle of the posterior lateral wall of the left ventricle (LV). Based on the course of the disease up to now, it was considered that the accumulation was most likely metastasis of CCS. Observation of the heart after a median sternotomy revealed a white tone, well-defined lesion in the middle of the anterolateral wall of LV. The tumour on the posterolateral side of LV was not exposed on the surface, but it was palpated and was still recognizable as a firm neoplastic lesion. Because the mass was identified as a sarcoma on intraoperative rapid pathology, we decide to perform a total resection. Both lesions were excised, and pathology revealed a diagnosis of CCS.
Discussion: Clear cell sarcoma is a very rare disease that accounts for <1% of all soft tissue sarcomas, and its occurrence in the heart is even rarer. It requires a combination of many imaging modalities. To our knowledge, this is the first case of CCS in the heart treated with surgical resection.

Brown adipose tissue (BAT) is an ideal target organ for obesity treatment. Resinacein S is extracted from Ganoderma lucidum and can elevate Uncoupling protein 1 (UCP1) in cells, but its related effects at the animal level are not clear. The mice were fed with high-fat diet to construct obesity models and treated with Resinacein S.

Efferocytosis refers to the process of phagocytes engulfing and clearing the cells after programmed cell death. In recent years, an increasing number of studies have shown that the mechanisms of efferocytosis are closely related to drug-induced liver injury, hepatic ischemia-reperfusion injury, viral hepatitis, cholestatic liver diseases, metabolic-associated fatty liver disease, alcoholic liver disease, and other liver disorders. This review summarized the research progress on the role of efferocytosis in liver diseases, with the hope of providing new targets for the prevention and treatment of liver diseases.

The connection between metabolic reprogramming and tumor progression has been demonstrated in an increasing number of researches. However, further research is required to identify how metabolic reprogramming affects interpatient heterogeneity and prognosis in clear cell renal cell carcinoma (ccRCC). In this work, single-cell RNA sequencing (scRNA-seq) based deconvolution was utilized to create a malignant cell hierarchy with metabolic differences and to investigate the relationship between metabolic biomarkers and prognosis.

Theileria parasites are known to induce the transformation of host bovine leukocytes, involved in rapid proliferation, evasion from apoptotic mechanisms, and increased dissemination. In this study, we reveal the involvement of mA RNA modification in T. annulata infection-induced transformation of bovine leukocytes.

N-methyladenosine (mA) modification and LncRNAs play crucial regulatory roles in various pathophysiological processes, yet roles of mA modification and the relationship between mA modification and LncRNAs in cadmium-induced oxidative damage of pancreatic β-cells have not been fully elucidated. In this study, mA agonist entacapone and inhibitor 3-deazadenosine were used to identify the effects of mA on cadmium-induced oxidative damage as well as LncRNA changes. Our results indicate that elevated levels of mA modification by entacapone can rescue the cell viability and attenuate the cell apoptosis, while the inhibition levels of mA modification can exacerbate the cell death.
