time that Rb2 exerted an anti‑inflammation effect on the process of endothelial cell senescence and could be a potential therapeutic drug by targeting miR‑216a.ABT‑737 is a recently reported inhibitor of members of the Bcl‑2 family of apoptosis regulators. However, to the best of our knowledge, its necroptosis‑inducing function in bladder cancer has not yet been researched. Thus, the present study aimed to investigate whether this Bcl‑2 family inhibitor can induce both apoptosis and necroptosis of urothelial carcinoma cells. The proliferation and survival of urothelial carcinoma cell lines treated with a combination of both Z‑VAD‑FMK as a pan‑caspase inhibitor and ABT‑737 were assessed in vitro. Z‑DNA binding protein 1 (ZBP1), receptor‑interacting protein (RIP)1 and RIP3 were knocked down using small interfering RNA in urothelial carcinoma cell lines. The protein expression levels of ZBP1, RIP1 and RIP3 following cell transfection were measured via western blot analysis. Cell viability was determined using an MTT assay. Cell invasion was examined using cell invasion assays. The expression levels of necroptosis‑related proteins, high mobility group box 1, ZBP1, mixed‑lineage kinase domain‑like protein (MLKL) and RIP3, were measured via western blotting. Elamipretide mw It was found that ABT‑737 inhibited the proliferation and invasion of bladder cancer cells by inducing cell necrosis. The data demonstrated that ZBP1 and RIP3 have main roles in the cell necrosis induced by ABT‑737. In addition, RIP3 and ZBP1, without interacting with RIP1, directly induced MLKL‑mediated programmed cell necrosis. Thus, understanding how urothelial carcinoma cells react to Bcl‑2 family inhibitors may accelerate the discovery of drugs to treat bladder cancer.Thyroid carcinoma (THCA) is a common type of endocrine system cancer and its current clinical treatment method is surgical resection. Long non‑coding RNAs (lncRNAs) have been revealed to serve important roles in a variety of complex human diseases. Therefore, determining the association between lncRNAs and diseases may provide novel insight into disease‑related lncRNAs, with the aim of improving disease treatments and diagnoses. Long intergenic non‑protein coding RNA 1816 (LINC01816) was identified to be associated with the survival of patients with colorectal cancer using the IDHI‑MIRW method. The present study aimed to investigate the role and molecular mechanism of LINC01816 in THCA. Analysis of datasets from The Cancer Genome Atlas database revealed that the upregulation of LINC01816 expression levels was associated with a variety of cancer types. Reverse transcription‑quantitative PCR analysis demonstrated that compared with the normal thyroid tissues, the expression levels of LINC01816 were upregulated in THCA tissues. The results of wound healing and Transwell assays, and western blotting demonstrated that the overexpression of LINC01816 could strengthen the invasive and migratory abilities of THCA cells and enhance epithelial‑mesenchymal transition progression. Analysis using the starBase website and dual‑luciferase reporter assays identified that microRNA (miR)‑34c‑5p was a target of LINC01816. The overexpression of miR‑34c‑5p could inhibit the invasive and migratory abilities of THCA cells, in addition to inhibiting the cellular retinoic acid binding protein 2 (CRABP2) overexpression‑induced effects on invasion, migration and EMT processes. In conclusion, the findings of the present study indicated that LINC01816 may be capable of sponging miR‑34c‑5p to upregulate CRABP2 expression levels, which subsequently promoted the invasion, migration and EMT of THCA cells. Therefore, targeting the LINC01816/miR‑34c‑5p/CRABP2 pathway may be an effective therapeutic approach for patients with THCA.Breast cancer (BC) impacts 2.3 million women each year, making it the most frequent cancer diagnosed among the female population. An unexpected link has been discovered between BC and alterations in the mammary and gut microbiota, suggesting their possible role in BC development, prevention and management. Studies suggest a distinct microbiome in healthy breast tissue compared to BC tissue. The healthy breast tissue has been found to be mostly enriched with bacteria of the phyla Proteobacteria, Firmicutes and Actinobacteria. However, certain bacteria are more abundant in cancerous tissues compared to adjacent non‑cancerous tissues in BC women or compared to the breast tissues of healthy women. On the other hand, bacteria such as Lactococcus spp. are increased in the breast tissues of healthy women compared to the cancerous tissues of BC women and may therefore have potential protective effects against BC. Additionally, preliminary studies propose that the mammary microbiota is distinct in the different subtypes of BC, proposing a specific role of microbes in the development of BC and suggesting their possible use as biomarkers. Similarly, dysbiosis in the gut microbiota has been further linked to BC since certain gut bacteria can alter the production of beneficial metabolites and disrupt estrogen metabolism in the gut. While still at its infancy, such unexpected links between breast and gut microbiota and BC propose possible alternatives with regards to the prevention but also management of BC such as through the use of probiotics. The current review is focused on evaluating the recent evidence regarding the association between mammary and gut microbiota and BC and discusses the most important bacteria involved.Circular RNAs (circRNAs) are a special class of recently re‑discovered RNAs, which are covalently closed ring RNA molecules. circRNAs have been reported to possess multiple functions and are considered crucial regulators of several processes, and are therefore gaining increasing attention. In recent years, increasing evidence has shown that circRNAs are implicated in several crucial biological processes via regulation of gene expression, and their dysregulation is also associated with the development of numerous diseases, particularly acting as oncogenic or tumor‑suppressor molecules in cancer. Furthermore, circRNAs are involved in cell proliferation, differentiation, apoptosis, invasion and metastasis. In the present review, the biogenesis and functions of circRNAs are described, with a focus on the most recent research advances and the emerging roles of circular homeodomain‑interacting protein kinase 3 (circHIPK3) in human diseases. The present review may provide novel avenues for research on the roles of circHIPK3 as a clinical diagnostic and prognostic biomarker, as well as highlighting promising therapeutic targets for certain diseases and cancer.
