Abstract
Forkhead box D1 (FOXD1) expression is upregulated in various types of human cancer. To the best of our knowledge, the roles of FOXD1 in prostate cancer (PC) remain largely unknown. The Cancer Genome Atlas dataset was used for the bioinformatics analysis of FOXD1 in PC. FOXD1 expression levels in normal immortalized human prostate epithelial cells (RWPE-1) and prostate cancer cells were detected by reverse transcription-quantitative PCR. PC cell viability was detected using Cell Counting Kit-8 assay. Transwell assays were performed to assess the migration and invasion of PC cells. Luciferase reporter gene assay was used to validate the association between FOXD1 and lamin (LMN)B1. LMNB1 is an important part of the cytoskeleton, which serves an important role in the process of tumor occurrence and development, regulating apoptosis and DNA repair. FOXD1 expression was upregulated in PC tissues, with its high expression being associated with clinical stage and survival in PC. Knockdown of FOXD1 inhibited viability, migration and invasion of PC cells. FOXD1 positively regulated LMNB1 expression. The effect of FOXD1 knockdown on PC cells was reversed by LMNB1 overexpression. In conclusion, FOXD1, positively regulated by LMNB1, served as an oncogene in PC and may be a potential biomarker and treatment target for PC.

Abstract
Forkhead box D1 (FOXD1) serves a critical role in colorectal cancer (CRC). FOXD1 expression is an independent prognostic factor in patients with CRC; however, the molecular mechanism and signaling pathway of FOXD1 that regulates cell stemness and chemoresistance has not been fully characterized. The aim of the present study was to further validate the effect of FOXD1 on the proliferation and migration of CRC cells, and to delve into the possible potential of FOXD1 in the clinical treatment of CRC. The effect of FOXD1 on cell proliferation was assessed using Cell Counting Kit 8 (CCK‑8) and colony formation assays. The effect of FOXD1 on cell migration was assessed by wound‑healing and Transwell assays. The effect of FOXD1 on cell stemness was assessed by spheroid formation in vitro and limiting dilution assays in vivo. The expression of stemness associated proteins, leucine rich repeat containing G protein‑coupled receptor 5 (LGR5), OCT4, Sox2 and Nanog, and epithelial‑mesenchymal transition associated proteins, E‑cadherin, N‑cadherin and vimentin, were detected by western blotting. Proteins interrelationships were assessed by a co‑immunoprecipitation assay. Oxaliplatin resistance was assessed using CCK‑8 and apoptosis assays in vitro, and using a tumor xenograft model in vivo. By constructing FOXD1 overexpression and knockdown stably transfected strains of colon cancer cells, it was revealed that the overexpression of FOXD1 increased CRC cell stemness and chemoresistance. By contrast, knockdown of FOXD1 produced the opposite effects. These phenomena were caused by the direct interaction between FOXD1 and β‑catenin, thus promoting its nuclear translocation and the activation of downstream target genes, such as LGR5 and Sox2. Notably, inhibition of this pathway with a specific β‑catenin inhibitor (XAV‑939) could impair the effects induced by the overexpression of FOXD1. In summary, these results indicated that FOXD1 may promote cell stemness and the chemoresistance of CRC by binding directly to β‑catenin and enhancing β‑catenin nuclear localization; therefore, it may be considered a potential clinical target.

Abstract
To investigate the mechanism of renal ischemia-reperfusion injury (IRI) via regulation of N6-methyl-adenosine (m6A) and relevant genes, IRI was induced in Sprague-Dawley rats, and urine and serum creatinine levels and tissue structure changes were observed. m6A and methyltransferase-like 3 (METTL3) protein levels were assessed via dot-blot and Western blot analyses, respectively. The hypoxia/reoxygenation (H/R) cell model was constructed using NRK-52E cells, and METTL3 protein levels were assessed. METTL3 was inhibited to observe its impact on NRK-52E cell apoptosis and m6A expression in H/R processes. Methylated RNA immunoprecipitation (MeRIP) sequencing was conducted followed by MeRIP-quantitative RT-PCR and quantitative RT-PCR validation. Our results indicated that urine and serum creatinine levels increased and that renal injury and cell apoptosis were both observed in the IRI model. In additon, m6A expression increased in the IRI model, and METTL3 protein levels significantly increased in the IRI and H/R models. When METTL3 was inhibited, m6A levels were accordingly decreased and cell apoptosis was suppressed in the H/R in vitro model. Based on MeRIP sequencing, transcription factor activating enhancer binding protein 2α (tfap2a), cytochrome P-450 1B1 (cyp1b1), and forkhead box D1 (foxd1) were significantly differentially expressed, as was m6A, which is involved in the negative regulation of cell proliferation and kidney development. We confirmed that foxd1 mRNA and its methylation levels contributed to IRI and H/R.
