Article Abstract
Background: Endometrioid ovarian carcinoma and clear cell ovarian carcinoma are both classified as endometriosis-associated ovarian cancer (EAOC). Despite the high rates of recurrence and mortality of EAOC, no prognostic biomarkers have been determined. ADP-ribosylation factor-like protein 4C (ARL4C) has been reported to be involved in various tumor progression processes, but its clinical significance for predicting prognosis in EAOC cases has never been studied.
Objective: The present study aimed to determine the clinical significance of ARL4C expression in EAOC prognosis.
Methods: ARL4C expression was semi-quantitatively evaluated via immunohistochemistry in 61 EAOC patients, and the correlations between ARL4C expression and clinicopathological data and survival were statistically analyzed.
Results: Thirty-six (59%) cases had high levels of ARL4C, which was related to worse 5-year overall survival (OS) (log-rank test, p= 0.036). In multivariate Cox proportional hazard model, high ARL4C expression was a significantly independent predictive factor for worse 5-year OS (hazard ratio = 12.048, p= 0.0201) and 5-year PFS (hazard ratio = 8.130, p= 0.0036).
Conclusions: ARL4C is a biomarker for worse prognosis and a novel therapeutic target in EAOC.

Background: Interstitial fibrosis and tubular atrophy (IFTA) represent significant histopathological manifestations contributing to long-term kidney allograft failure after transplantation. Identifying M2 macrophage (Mφ2)-related biomarkers could enhance early diagnosis and prognosis prediction, improving patient outcomes. This study aimed to explore Mφ2-related biomarkers for IFTA via bioinformatics and machine learning approaches.

Foam cells are the risk factors for atherosclerosis. Recently, ARL4C, a member of the ADP-ribosylation factor family of GTP-binding proteins, was found to promote cholesterol efflux to decrease foam cell formation, suggesting that ARL4C may be a new promising target for the treatment of atherosclerosis. In fact, ARL4C regulated the expression of multiple atherosis-related genes, including ABCA1, ALDH1A3, ARF6, ENHO, FLNA, LRP6, OSBPL5, Snail2, and SOX2.

Colorectal carcinoma (CRC) is a deadly cancer with an aggressive nature, and how CRC tumor cells manage to translocate and proliferate in a new tissue environment remains not fully understood. Recently, higher-order chromatin structures and spatial genome organization are increasingly implicated in diseases including cancer, but in-depth studies of three-dimensional genome (3D genome) of metastatic cancer are currently lacking, preventing the understanding of the roles of genome organization during metastasis. Here we perform multi-omics profiling of matched normal colon, primary tumor, lymph node metastasis, liver metastasis and normal liver tissue from CRC patients using Hi-C, ATAC-seq and RNA-seq technologies.

The changes in the level of small GTPase ARL4C are associated with the initiation and progression of many different cancers. The content of ARL4C varies greatly between different tissues, and the induction of ARL4C expression leads to changes in cell morphology and proliferation. Although ARL4C can bind alpha-tubulin and affect intracellular transport, the role of ARL4C in the functioning of the tubulin cytoskeleton remained unclear.

Low-grade gliomas are divided into two main genetic phenotypes based on the presence or absence of mutations in the isocitrate dehydrogenase () genes. The mutated IDH phenotype (IDHmut), in contrast to the wild-type phenotype (IDHwt), is characterized by a more positive response to pharmacological intervention and a significantly longer survival time. In this study, we analyzed the differential co-expression of 225,000 microRNA-mRNA pairs at the level of correlations between microRNA levels and their potential mRNA targets.
