Background: Uveal melanoma (UM) is a common intraocular malignancy in adults frequently with metastasis and poor survival.
Objective: This study aimed to identify genes, pathways and the ceRNA axes related to the metastasis of UM.
Methods: The GSE73652 dataset was downloaded and 1719 differentially expressed RNAs (DE-RNAs), including 13 lncRNAs, 5 miRNAs, and 1701 genes, were identified in metastatic UM samples compared with non-metastatic ones.
Results: A total of 11 lncRNA-miRNA pairs were identified by interviewing the DIANA-LncBase database. In addition, 49 UM-related KEGG pathways were filtered in CTD with the search term "uveal melanoma". KEGG pathways involving the differentially expressed genes (DEGs) among the miRNA targets were found and overlapped with UM-related pathways. Accordingly, two crucial overlapped pathways (Wnt and Chemokine signaling pathway) in UM metastasis were mediated by axes consisting of 6 lncRNAs (such as H19, PVT1 and SNGHG1), 3 miRNAs (including hsa-miR-1228, hsa-miR-106b and hsa-miR-6836) and 12 mRNAs (including CTNNB1, MAP3K7, WNT7B, MAPK10 and PLCB4).
Conclusion: The results showed that the involvement of UM-related Wnt/β-catenin and Chemokine signaling pathways and the ceRNA regulatory axes showed noteworthy interest in UM metastasis.

Background: Asian cancer patients have become the highest morbidity and mortality group, and gastrointestinal tumors account for the majority of them, so it is urgent to find effective targets. Therefore, ferroptosis-related lncRNAs models were established to predict the prognosis and clinical immune characteristics of GI cancer.
Methods: RNA sequencing and clinical data were collected from the TCGA database (LIHC, STAD, ESCA, PAAD, COAD, CHOL, and READ) of patients with gastrointestinal cancer in Asia.

Prostate cancer has garnered much importance in recent years due to its rising incidence and mortality among men worldwide. The ineffectiveness of existing therapies and adverse events associated with conventional treatment have led patients to turn towards traditional medicine for the management of prostate cancer. Cinnamomum zeylanicum bark essential oil (CZEO) possesses promising anticancer properties, yet the exact mechanism of action of CZEO for the management of prostate cancer remains unclear.

Background: Hidradenitis suppurativa (HS) is a chronic, inflammatory and common skin disease. Observation studies have reported the association between HS and cancers, however no studies reported whether a causal relationship exists between HS and cancers. This study aimed to explore the causal relationship between HS and differential subtypes of cancers by conducting a bidirectional Mendelian randomization (MR) analysis.

(1) Background: (CE) is an -induced worldwide parasitic zoonosis and is a recognized public health and socio-economic concern. The liver is the major target organ for CE's infective form protoscolex (PSCs), which causes serious liver damage and endangers the host's life. Reports show that PSC infection causes liver cell Fe metabolism disorder and abnormal deposition of Fe in liver cells and results in liver cell death.

Introduction: The adverse effects of goose astrovirus (GoAstV) on avian growth and health have been widely reported previously, while the stress reactions and corresponding mechanism of gosling liver responding to GoAstV infection remain not entirely clear.
Methods: One-day-old goslings inoculated subcutaneously with 2 × 10 TCID of GoAstV were employed as an experimental model, and the potential effects and pathways of GoAstV infection on gosling liver functions were investigated by combining the morphological, biochemical and RNA sequencing (RNA-seq) techniques.
Results: Structural and functional impairments were found in gosling livers post the virus infection, as characterized by the histological alterations in liver index and morphology of hepatic cord and sinuses, as well as the abnormal expression patterns of the cellular antioxidant, inflammation and apoptosis-related genes.
