Introduction Recent breakthrough recognition of metastasis-free survival as a clinically relevant endpoint has opened a new era in the management of advanced prostate cancer. selective HDAC inhibitors The need for new, intermediate endpoints is the logical consequence of scientific advances in prostate carcinoma. The treatment algorithms for non-metastatic castration-resistant prostate cancer (M0 CRPC) have recently been updated by adding novel anti-androgen apalutamide, and also enzalutamide for high-risk patients. Objective To review clinical evidence of metastasis-free survival as an efficacy endpoint used in prostate cancer studies, especially those in an advanced stage of the disease and identify its clinical benefit and correlation with overall survival. Methods Literature search up to October 2019 was conducted, including clinical trials and clinical practice guidelines. Evidence synthesis Metastasis-free survival (MFS) was used as the primary endpoint in the registration of clinical trials of second-generation anti-androgens. The study results have demonstrated the beneficial effect of these anti-androgens on delaying the development of metastases or death (MFS), with median MFSextended by 22‒24 months. The correlation tests have shown a positive correlation of MFS and overall survival. Conclusion The metastasis-free survival can be considered a clinically significant and reliable efficacy endpoint in both localized prostate cancer patients and M0 CRPC patients being at high-risk of disease progression (Ref. 15).Aim The present study investigated the role of redox balance, inflammation, mitochondrial dysfunction, and apoptosis in Tramadol (Tra)-induced testicular toxicity. Method Twenty-four male Wistar rats were randomly divided into either the control group or the groups receiving different doses of Tra (25, 50, and 75 mg/kg/day, i.p.) for 21 successive days. Testicular tissues were collected for oxidative stress, mitochondrial function, sperm assays and histopathological evaluation. Real-time polymerase chain reaction was performed to evaluate the markers of inflammation and apoptosis. Results Tra caused a significant reduction in the sperm count, motility and morphology, while it caused a marked increase in oxidative stress parameters. In addition, Tra induced testicular mitochondrial dysfunction due to the collapse of mitochondrial membrane potential and mitochondrial swelling. It also led to the significant inhibition of anti-apoptotic Bcl-2 expression, besides a significant increase in pro-apoptotic Bax expression. There was a significant increase in the level of tumour necrosis factor-α, interlukin-1β and nuclear factor kappa B. Histopathological degenerative changes were observed in the testis after Tra exposure. Conclusions The present results suggest that Tra exposure may lead to reproductive toxicity due to the loss of the antioxidant defence system, mitochondrial dysfunction, and activation of inflammatory and apoptotic pathways (Tab. 4, Fig. 5, Ref. 63).Aims Visual snow is a neurological condition, for which an effective treatment has not been established. The aim of this study was to find whether Repetitive Transcranial Magnetic Stimulation (rTMS) can improve the state of patients suffering from visual snow. To our knowledge, no other group has tested this method in the treatment of visual snow. Methods We applied rTMS of 10 and 10+1 Hz on the visual cortices of 9 patients with visual snow. Sham stimulation with the vertex as the target site was also tested. As a method of assessment, we used visual evoked potentials, questionnaires and visual snow diaries. For data evaluation, we used the Paired Sample T-test separately for each stimulation type. Results The Paired Sample T-test revealed a decreased sum of visual snow intensities extracted from visual snow diaries in the week after 10+1 Hz stimulation as compared to the figure in the week before (p=0.02). Conclusion We detected a trend indicating an improvement of patients' condition based on the data from visual snow diaries. Research on a larger group of patients is required to confirm these findings; however, our study provides a framework to build upon (Tab. 4, Fig. 1, Ref. 22).Aim This article presents the development of a novel preparation and processing method as well as indication for clinical applications of human allogeneic acellular dermal matrix, which was developed originally in the Central Tissue Bank (CTB) for use in burn medicine and reconstructive surgery. Methods Acellular dermal matrix (ADM) is a biological material assigned for utilization in several surgical procedures due to its unique structure and advantageous properties. The article focuses on a novel preparation and processing method developed by CTB, which differs in its impact on the structure, biological and biomechanical properties of the final ADM compared to the wide range of commercially available ADM products and currently available ADM products of other tissue banks. Results The ubiquitous acellular allogeneic dermal collagen matrix is the main substance participating in advantageous properties facilitating the use of ADM in numerous indications from dermal replacement and soft tissue augmentation to mmes (Fig. 9, Ref. 60).Aim The purpose of this retrospective study was to perform an evaluation of postoperative positional changes of the condyle and mandibular function after bilateral sagittal split osteotomy (BSSO) with manual proximal segment positioning. Patients 45 patients were divided into the 2 groups ‒ G1 (advancement ‒ 14 patients) and G2 (setback - 31 patients). Rigid internal fixation screws were utilized in all cases. Inclusion criteria were only BSSO, no TMJ symptoms preoperatively and age 18 or older. Results The differences between pre- and postoperative condyle position were evaluated using measurements taken from preoperative CT scans and compared to CT scans made a minimum of 6 months postoperatively. The positional changes in both the axial and sagittal planes were measured and compared. The recovery of mandibular function was evaluated by measuring maximal interincisal opening (MIO). The results revealed that condylar positional changes after BSSO in both groups were minimal and not significantly different for all three dimensions measured. The recovery of mandibular function was faster in the group G2 than in the group G1. Mandibular function reached almost preoperative level in 6-12 months postoperatively in both groups. Conclusion The results demonstrated that following BSSO, only insignificant condylar displacement and functional changes occurred within 6 to 12 months postoperatively (Tab. 4, Fig. 2, Ref. 47).Death inducer obliterator (DIDO) is involved in apoptosis and embryonic stem cell self-renewal. Here, we investigate the effect of DIDO1 on bladder cancer cells and clarify the underlying molecular mechanism. Bladder cancer tissues and cell lines (T24, ScaBER, 5637), as well as normal bladder epithelial cells (SV-HUC-1), were used to measure the levels of DIDO1 mRNA and protein by qRT-PCR and western blot, respectively. The results indicated that DIDO1 was highly expressed in bladder cancer tissues and cell lines. And the expression of DIDO1 in T24 and 5637 cells was higher than that in ScaBER and SV-HUC-1 cells. The expression of DIDO1 was knocked down in T24 and 5637 cells by infection with shDIDO1-1 and shDIDO1-2 lentivirus. The growth of T24 and 5637 cells was monitored using Celigo, MTT assays, and colony formation assay. Apoptosis was examined by flow cytometric analysis. The effect of DIDO1 knockdown on tumorigenesis of T24 xenograft tumors was determined in nude mice. Reduction of DIDO1 mRNA resulted in reduced proliferation, decreased cell colony formation, increased apoptosis in vitro, and inhibited tumorigenesis in vivo. Furthermore, we identified signaling molecules involved in stress and apoptosis using the PathScan Antibody Array Kit and western blot. The depletion of DIDO1 significantly decreased the levels of phosphorylated SAPK/JNK, and Chk1/2, as well as the upregulating cleaved Caspase-7 expression. These results indicated that the potential mechanism of DIDO1 action might involve SAPK/JNK signaling cascades.microRNA-34a (miR-34a) and microRNA-1251-5p (miR-125a-5p) were considered as tumor suppressors in hepatocellular carcinoma (HCC). Nevertheless, the modulatory mechanisms of miR-34a and miR-125a-5p in HCC haven't been completely understood. The levels of metastasis-associated with colon cancer 1 (MACC1) and miRNAs (miR-34a and miR-125a-5p) were determined by quantitative real-time polymerase chain reaction (qRT-PCR), and the levels of associated proteins were detected by western blot assay. Cell proliferation and metastasis were examined via Cell Counting Kit-8 (CCK-8) and transwell assays, respectively. Cell apoptosis was measured through flow cytometry. The effect of MACC1 on HCC in vivo was explored via xenograft assay. Dual-luciferase reporter assay and RNA Immunoprecipitation (RIP) assay were implemented to explore the target correlation. The expression of MACC1 was upregulated in HCC tissues and cells. Knockdown of MACC1 inhibited proliferation and metastasis but expedited apoptosis of HCC cells and the repression of tumor growth in vivo was evoked by MACC1 downregulation. Both miR-34a and miR-125a-5p directly targeted MACC1 and repressed the expression of MACC1 in HCC cells. Overexpression of miR-34a or miR-125a-5p restrained cell proliferation and metastasis while induced apoptosis by downregulating MACC1 in HCC cells. miR-34a and miR-125a-5p repressed phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signal pathway via reducing MACC1 in HCC cells. miR-34a and miR-125a-5p refrained proliferation and metastasis while motivated apoptosis in HCC cells through the PI3K/AKT/mTOR pathway by repressing MACC1. miR-34a and miR-125a-5p might be splendid biomarkers in the therapeutic strategies for HCC.The kelch like family member 22 (KLHL22) is a member of the KLHL (Kelch-like) gene family, which was involved in the progression of breast cancer. However, its role remains unclear in malignant melanoma (MM). Our study found that KLHL22 expression was upregulated in human MM tissues. Regarding the functional analysis for KLHL22 in the progression of MM cells, we demonstrated that overexpression of KLHL22 could promote MM cell growth in vitro. Vice versa, knockdown of KLHL22 could suppress the proliferation of MM cells. Furthermore, KLHL22 also promoted tumorigenesis of MM cells in vivo. In experiments investigating the underlying mechanism, expressions of p-Akt and p-mTOR were significantly increased by overexpression of KLHL22. Meanwhile, knockdown of KLHL22 could decrease the expression levels of p-Akt and p-mTOR. Our studies thus suggest that KLHL22 can promote the growth of MM cells via activating the PI3K/Akt/mTOR signaling pathway, which can serve as a potential target in the diagnosis and/or treatment of MM.Gastric cancer (GC) is the second leading cause of cancer-associated deaths worldwide. Tanshinone IIA (TSN) is the pure extract from the root of red-rooted salvia and has been reported to inhibit the progression of GC cells. In this study, we investigated the microRNA (miRNA) mediated gene repression mechanism in TSN-administrated GC condition. The cell viability of GC was determined by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay. Cell migration and invasion were detected by transwell assays. The expression levels of epithelial-mesenchymal transition (EMT)-associated proteins (N-cadherin, vimentin, E-cadherin), High-mobility group box proteins 2 (HMGB2), β-catenin pathway-related proteins (β-catenin, c-myc, cyclin D1) were detected by western blot analysis in TSN/GC. The expression patterns of miR-874 and HMGB2 in GC were determined by quantitative real-time polymerase chain reaction (qRT-PCR). The potential miR-874-targeted HMGB2 was searched via bioinformatic methods and identified by dual-luciferase reporter assays, and RNA immunoprecipitation (RIP) assays, and RNA Pull-down assays.
