Cathepsin S (CTSS), a lysosomal cysteine protease, is overexpressed in various cancers, including glioblastoma (GB). A high level of CTSS is associated with tumor progression and poor outcome in GB. However, the underlying mechanisms of its role in the biological characteristics of G5B remain to be elucidated. Here, we uncovered a potential role of CTSS in the lysosomes and mitochondria of GB cells (GBCs). Downregulation of CTSS in GBCs could increase the expression of autophagy-related proteins; however, there was no significant change in p62, suggesting autophagy blockade. Moreover, inhibition of CTSS increased the expression of mitochondrial calcium uniporter (MCU) and enhanced mitochondrial Ca2+ uptake ability, causing mitochondrial Ca2+ overload, the generation of copious reactive oxygen species (ROS) and eventual mitochondrial apoptosis. Additionally, elevated damage to mitochondria exacerbated the burden of autophagy. Finally, we found that silence of MCU could alleviate the inhibition of CTSS-induced autophagosome accumulation and mitochondrial stress. Collectively, these results demonstrate that CTSS plays an important role in the process of autophagic flux and mitochondrial functions in GBCs.

Mucinous tumors of the prostate are seen as rare morphological variants of prostate carcinoma. Misdiagnosis and missed diagnosis are frequent clinically, especially when the clinical performance appears atypical. Furthermore, there has not been reported about the urethrocystoscopic performance of mucinous adenocarcinoma growing into the prostatic urethra so far.

The current case report describes a 48-year old Asian male who was hospitalized because of intermittent gross hematuria for more than two months. SU5416 in vivo The patient was diagnosed as prostatic space occupying lesions and an examination of needle biopsy was conducted on him, which did not indicate a definite malignancy. Transurethral plasma kinetic resection of the prostate (TUPKP) was performed for the patient, but the postoperative pathology revealed prostatic adenocarcinoma with mucinous features. Specifically, two cord-like neoplasms, extending to the bladder neck, were found through urethrocystoscopy in the prostatic urethra, both of which grew pedicln for the first time.Breast cancer is among the frequently occurring cancer worldwide. The foremost underline aim of this study was to determine the growth inhibitory effect along with mechanistic study of a Bruguiera gymnorrhiza extract on MCF-7. The cytotoxicity activity was determined by using the MTS assay. Butanol extract exhibited the maximum cytotoxicity activity against the MCF-7 cells with IC50 of 3.39 μg/mL, followed by diethyl ether and methanol extract (IC50 at 16.22 μg/mL and 37.15 μg/mL, respectively) at 72 h. The DeadEndTM Colorimetric Apoptosis Detection System confirmed the induction of apoptosis (via DNA fragmentation) in MCF-7 cells. Both butanol and diethyl ether extracts of B. gymnorrhiza significantly increase the caspase-3 level. However, the diethyl ether extract induced higher caspase-9 levels compared to caspase-8, suggesting that the intrinsic pathway was the major route in the process of apoptosis. Thin-layer chromatography profiling demonstrated the presence of phenolic, terpene, and alkaloid compounds in crude methanol, diethyl ether, and butanol extracts. The phytochemicals present in the extracts of B. gymnorrhiza might have the potential to be a future therapeutic agent against breast cancer.Jatropha sap (JTS), an important fluid carried in xylem and phloem tubes of Jatropha multifida L. plant, has good wound healing property. However, physicochemical stability of JTS needs to be improved in order for it to be useful as a topical wound-healing agent. In this study, we developed an iota carrageenan-polyvinyl alcohol (IC-PVA) hydrogel film (HF) as a carrier of JTS and evaluated its wound-healing ability. The characterization of JTS secondary metabolites by ultraviolet-Vis spectrophotometry suggested presence of flavonoid, saponin, and alkaloids in the sap. We successfully extracted IC from Euchima spinosum using alkaline solvent at 80°C-90°C with calcium chloride as the precipitator. The result of computer simulation using Discovery Studio software and Autodock Tools showed the presence of hydrogen bonding interaction of IC-PVA. IC-PVA/JTS HF with excellent physical properties including high swelling ratio (246.32%) and high gel fraction (16.75%). In addition, irritation test in mice confirmed the absence of hypersensitivity reaction, redness, and allergic reactions. Interestingly, IC-PVA/JTS HF significantly accelerated wound healing when compared to the nontreated group/control with 98% wound closure by 10 days. These results suggest that IC-PVA HF has improves wound-healing ability of JTS.Cocos nucifera Linn., which contain lauric acid has been known had antibacterial activity against Propionibacterium acnes that usually improve severe of pimple. Current study investigated optimum formula of emulgel mask based on the C. nucifera L. Extract from Kopyor coconut. Extract were tested for antibacterial against P. acnes ATCC 11827. In this research, C. nucifera L. extract of 1 and 5% were formulated as an active agent of peel off antiacne emulgel mask-containing carbomer 940 in various concentration (1% and 1.5%). The peel-off emulgel mask of C. nucifera L extract was then evaluated in terms of viscosity, pH, drying time, spreadability, and antibacterial activity. The selected formula was formula containing 5% of extract and 1% of carbomer 940. This formula had pH that suitable with skin pH 4.5-6.5, had good spreadability, and also produced highest antibacterial activity against P. acnes.The advanced, metastasis, and reccurent of osteosarcoma (OS) patients have a poor prognosis postaggresive surgery and chemotherapy. Peripheral blood mononuclear cells (PBMCs) as cell-based immunotherapy may successful in the OS treatment. To investigate the enhancement apoptosis of OS-mesenchymal stem cells (OS-MSCs) co-cultivated with PBMCs sensitized using the secretome and granulocyte macrophage colony-stimulating factor (GMCSF). This true experimental study with posttest only control group design and in vitro study. The sample was cultured OS-MSCs which confirmed by Cluster of Differentiation-133 using immunocytochemistry (ICC) and histopathology analysis. The sample divided into six groups accordingly OS-MSC, OS-MSC + PMBC, OS-MSC + PMBC + Secretome, OS-MSC + PMBC + GMCSF, OS-MSC + PBMC + Secretome + GMCSF (n = 5/N = 30). The enhancement of OS-MSCs apoptosis was analyzed through Interleukin-2 (IL-2) level through the Enyzme-Linked Immunosorbent Assay examination, expression of Signal Transducers and Activators of Transcription (STAT)-3 and caspase-3 by ICC.
