Malignant melanoma is a highly lethal disease, and advanced stages of melanoma have proven to be resistant to many chemotherapeutic drugs including temozolomide and paclitaxel. Cancer stem cells (CSCs) have been identified and isolated in different cancers including melanoma, and have been proven playing important role in the drug resistance. Retinoic acid (RA) is a promising anticancer agent, which can induce differentiation of CSCs. The main purpose of the present study was to evaluate the possible RA-induced differentiation of melanoma CSCs and sensitization of melanoma CSCs to paclitaxel...

Tumstatin7 (CNYYSNS) is an antitumor peptide derived from the NC1 domain of Type IV collagen that has been associated with tumor angiogenesis. In this work, we generated a peptide composed of tumstatin7 fused to TAT, a cell-internalizing peptide consisting of 11 amino acids. Tumstatin7-TAT was internalized by cells and triggered cell death. The new peptide was more potent in inducing B16F10 melanoma cell apoptosis in vitro than the shorter tumstatin7. Whereas tumstatin7-TAT significantly reduced tumor cell viability, tumstatin7 showed only weak effects even at the highest treatment concentration applied...

Recently, many kinds of microRNAs (miRNAs) have been found to play a critical role in progression of osteosarcoma (OS). miR-217 was reported to function as a tumor suppressor in a number of human cancers but its precise mechanism to exert the suppressive role remains to be investigated. In this study, we found that miR-217 was downregulated in OS tissues and its downregulation predicts poor overall survival of OS patients. Importantly, we found that a lower expressed miR-217 in OS cell lines inhibited the cell proliferation and invasion in vitro ...

Propofol has been considered as a near-ideal anesthetic agent since its introduction 40 years ago. However, the side effects of propofol including bacterial contamination, hyperlipidemia, and neurotoxicity also aroused attention. Nerve growth factor (NGF) plays a pivotal role in the development, differentiation, and survival of the neurons of the peripheral and central nervous system. In the present study, we found that NGF alleviated the apoptosis induced by propofol in hippocampal neurons. Furthermore, NGF treatment augmented the protein abundance and mRNA level of Rac1 while silencing Rac1 significantly blunted the effects of NGF upon propofol-induced apoptosis...

Ulinastatin vaginal suppositories, used to prevent threatened premature delivery, are frequently used in hospitals. However, there is no established method for quantifying ulinastatin contained in suppositories. Therefore, we investigated a simple and efficient method for quantifying ulinastatin contained in suppositories. Our analytical method involved removal of the base; optimising the enzyme inhibition reaction time and enzyme reaction time; and measuring the absorbance. The modified method was reproducible, operation time was significantly shortened, and cost was reduced to approximately 1/17 of that of the previously reported method...

Cleopatra VII (69-30 BC), the last Ptolemaic ruler of Egypt, is probably best known for her love affairs with Julius Caesar (100-44 BC) and Marcus Antonius (83-30 BC). Rightly or wrongly she became the epitome of shrewd seduction, leading brave Roman commanders on a path to debauchery and destruction. Among the seductive strategies attributed to her is the ingestion of small amounts of turpentine [the resin of the terebinth tree ( Pistacia terebinthus )] or of derived oil ( Oleum terebinthinae ) with the purpose of conferring to her urine a more pleasant scent reminding of violets...
