An 84-year-old female presented with bilateral scotomas and progressive nyctalopia over 1 year. Best-corrected visual acuity was 20/50 in both eyes with reduced color vision. Goldmann visual field showed bilateral cecocentral scotomas and generalized constriction of the visual fields. This led to an electroretinogram showing an electronegative pattern consistent with autoimmune retinopathies. Infectious workup was negative. Anti-retinal antibodies were positive, leading to a presumed diagnosis of cancer-associated retinopathy (CAR). Imaging showed a previously unknown left renal lower pole mass, and she underwent a radical nephrectomy. Biopsy showed nuclear grade-3 clear cell renal carcinoma staged T1. The patient was treated with oral prednisone with no ocular improvement. We report on a rare case of clear cell renal carcinoma causing CAR. CAR is an important paraneoplastic syndrome to diagnose since the majority of ocular cases precede other manifestations of malignancy. Therefore, a timely diagnosis of CAR can be lifesaving or at least life-extending.

Background: DNA methylation (DNAm) data from human samples has been leveraged to develop "epigenetic clock" algorithms that predict age and other aging-related phenotypes. Some DNAm clocks were trained using DNAm obtained from blood cells, while other clocks were trained using data from diverse tissue/cell types. To assess how DNAm clocks perform across non-blood tissue types, we applied DNAm algorithms to DNAm data generated from 9 different human tissue types.

Inflammation, a central process in numerous diseases, plays a crucial role in hepatic disorders, arthritis, cardiac conditions, and neurodegenerative ailments. Given the lack of effective anti-inflammatory drugs, it is imperative to assess inflammation severity and explore novel therapeutics. Selenocysteine (Sec), a key mediator of selenium's biological function, is closely involved in anti-inflammatory responses.

Enhancer RNA (eRNA) has emerged as a key player in cancer biology, influencing various aspects of tumor development and progression. In this study, we investigated the role of eRNAs in kidney renal clear cell carcinoma (KIRC), the most common subtype of renal cell carcinoma. Leveraging high-throughput sequencing data and bioinformatics analysis, we identified differentially expressed eRNAs in KIRC and constructed eRNA-centric regulatory networks.

Background: Tumor microenvironment (TME) plays a crucial role in tumor growth and metastasis. Exploring biomarkers that are significantly associated with TME can help guide individualized treatment of patients.
Methods: We analyzed the expression and survival of P4HB in pan-cancer through the TCGA database, and verified the protein level of P4HB by the HPA database.
