2.The regulation of Cathepsin B on cell apoptosis induced by SAHA in breast cancer cell line MCF-7
Chinese Pharmacological Bulletin 2016;32(8):1086-1090
Aim To clarify the regulation role of ca-thepsin B ( Cat B ) in cell proliferation and apoptosis induced by SAHA in ER-positive breast cancer cell line MCF-7.Methods MTT was used to screen the optimal concentration and treatment time of SAHA . The expression levels of related proteins were deter-mined by ELISA , and the morphological changes were observed through time-lapse live cell imaging acquisi-tion.Cell viability and apoptosis assay in MCF-7 cells were assessed by Muse Cell Analyzer with SAHA and /or Cystatin C treatment .Results MTT assay showed that the anti-tumor efficacy of SAHA was significant . The optimal concentration and treatment time were 10μmol? L-1 and 24 h respectively . ELISA assay showed that SAHA could induce expression of Cat B in MCF-7 cells.Real-time live-cell imaging experiments demonstrated that the combination treatment of Cystatin C and SAHA significantly resumed the inhibitory effect caused by SAHA alone .Cytology test showed that SA-HA alone obviously depressed the cell viability and in-duced apoptosis . However , the effect was reversed with the combination of Cystatin C .Conclusion Cat B plays an important role in apoptosis induced by SAHA in ER +breast cancer cells MCF-7.

Objective To investigate the value of neuronavigation system in resection of pituitary adenoma through the endonasal transsphenoidal approach. Methods Twenty-one patients with pituitary adenomas underwent magnetic resonance imaging (MRI) or CT scans studies. The image datasets were transported into the neuronavigation system. The anatomic information of approach was reconstructed for three-dimensional visualization and the best approach was designed. The midline structure and internal carotid artery were displayed in real-time intraoperatively, the anterior-wall of sphenoidal sinus and the floor of sella were accurately opened and the tumor was resected guiding by neuronavigation system. Results All the operations were smoothly and accurately performed under the neuronavigation by transsphenoidal approach. No injury occurred in the internal carotid artery and cavernous sinus. After surgery, 13 patients got better vision and visual field. Postoperative transient diabetes insipidus was found in 11 cases, and CSF leak in 1 and serious hyponatremia in 2 cases. Total tumor removal was achieved in 17 patients and subtotal removal in 2 cases during operations, which were confirmed by postoperative MRI. Three-month follow-up data showed only one recurrence case (subtotal tumor removal), the recurrence rate was 4.8%. Conclusion Neuronavigation system provided real-time localization with three-dimensional anatomic information of the endonasal transsphenoidal approach during pituitary adenomas surgery. As a result, the approach proceeds more smoothly and accurately, the tumor can be resected more completely, the surgical injury and complications can also be reduced.
