Prostate cancer is the second highest caused by cancer-related death among males. microRNAs (miRs) have been reported to participate in carcinogenesis, yet their roles in prostate cancer are rarely studied or investigated. Therefore, the present study attempted to explore the effect of miR-137 in prostate cancer via regulating NADPH oxidase 4 (NOX4). Initially, microarray analysis was performed to obtain prostate cancer-related differentially expressed genes and miRs that regulated NOX4, followed by detecting the expression of miR-137 and NOX4 and its target relationship. Moreover, PC-3 cells were transfected with small interfering RNA (siNOX4) and miR-137 mimic for exploring the effect of miR-137 on glycolysis, cell proliferation, and apoptosis in prostate cancer by evaluating lactate production, glucose uptake, adenosine triphosphate (ATP) production, viability rate, and expression of cleaved caspases 3, 8, and 9, cytochrome c, cleaved poly ADP ribose polymerase (PARP), Bax, and Bcl-2. miR-137 was vital to prostate cancer progression via regulating NOX4. Besides, miR-137 expressed poorly while NOX4 expressed highly in prostate cancer. NOX4 was the target gene of miR-137. Additionally, overexpression of miR-137 and silencing of NOX4 were observed to decrease NOX4 and Bcl-2 protein expression, but increase cleaved caspases 3, 8, and 9, cytochrome c, cleaved-PARP, and Bax protein expression. Furthermore, miR-137 overexpression and NOX4 silencing contributed to decreased lactate production, glucose uptake, ATP production, and cell proliferation, but increased apoptosis rate. Collectively, the present study showed that miR-137 repressed glycolysis in prostate cancer through knockdown of NOX4, which might be a potential theoretical target for prostate cancer treatment.

Downregulated NOX4 underlies a novel inhibitory role of microRNA-137 in prostate cancer.

Despite major advances in combating pathogenic bacteria caused infection, infectious diseases remain a major cause of death today. A variety of bacteria detection approaches have been established by exploiting the aptamer to specifically identify target. However, these methods require specific equipment or laboratory based instruments, which is expensive and not easily available to the public. To deal with this issue, we develop here a portable and sensitive pathogenic bacteria detection approach through integrating capture probe based recognition and Exo-III assisted signal amplification. In this method, a designed capture probe identifies the surface protein of target bacteria, leading to the release of blocker sequence. The released blocker sequence mediates Exo-III enzyme based signal amplification, generating a large amount of signal strand DNA (ssDNA) sequences. The obtained ssDNA works as a linker to conjugate streptavidin magnetic beads (SMBs) with DNA invertase. After magnet based enrichment and washing away of free DNA invertase, the SMBs-DNA invertase complex is used to catalyze the hydrolysis of sucrose into glucose for PGM readout. Based on this, the approach exhibits a 6 order of magnitudes in detecting Staphylococcus Aureus (S. aureus) with the limit of detection as low as 78 cfu/mL. In addition, the capability to specifically detect target bacteria and high repeatability (relative standard deviation, 4.44%) endows the method wider applicable scenes. In all, the established shows a promising prospect in the detection of bacteria pathogen and the early-diagnosis of bacterial infections.
