Abstract
Rapid advances in nanomedicine have enabled potential applications in cancer therapy. The enhanced permeability and retention (EPR) effect is the primary rationale for the passive targeting of nanoparticles in oncology. However, growing evidence indicates that the accumulation of nanomaterials via the EPR effect could be more efficient. Inspired by our clinical observation of the Gap Junction connecpion between folliculostellate cells and pituitary adenoma cells, we designed a novel drug delivery system that targets tumours by coating folliculostellate cell (FS) membranes onto PLGA nanoparticles (NPs). The resulting FSNPs, inheriting membrane proteins from the folliculostellate cell membrane, significantly enhanced the EPR effect compared to nanoparticles without cancer cell membranes. We further demonstrated that mitotane encapsulation improved the therapeutic efficacy of mitotane in both heterotopic and orthotopic pituitary adenoma models. Owing to its significant efficacy, our FS cell membrane-coated nanoplatforms has the potential to be translated into clinical applications for the treatment of invasive pituitary adenoma.

Abstract
BACKGROUND The role and mechanism of long non-coding RNA cytoskeleton regulator (CYTOR) in Invasive Pituitary Adenomas (IPA) have not been elucidated previously. OBJECTIVE This study aimed to investigate the interaction between CYTOR and miR-206 and their roles in IPA using HP75 cells as the model. METHODS The expression levels of CYTOR and miR-206 were detected by quantitative real-time polymerase chain reaction (qRT-PCR) in IPA tissues and cell lines. The Chi-square test was used to analyze the correlation between CYTOR expression and clinical-pathological parameters. HP75 cell proliferation was detected by Cell Counting Kit-8 assay and colony formation assay. Scratch healing experiments and Transwell assay were used to detect migration and invasion of HP75 cells. The relationship between CYTOR and miR-206 was predicted by bioinformatics and verified by qRT-PCR and the dual-luciferase reporter gene method. RESULTS CYTOR is up-regulated in IPA tissues and cell lines. The high expression of CYTOR is associated with adenoma invasiveness and adenoma size of the patients. Down-regulation of CYTOR decreases the proliferation, migration and invasion of HP75 cells, while up-regulation of miR-206 can inhibit proliferation, migration and invasion of HP75 cells. MiR-206 is identified as a target of CYTOR and could be negatively regulated by it in IPA. DISCUSSION CYTOR, as a tumor-promoting factor, facilitates the proliferation, migration and invasion of HP75 cells through sponging miR-206. CONCLUSION The CYTOR-miR-206 axis provides new insights into the diagnosis and treatment of IPA.

Abstract
BACKGROUND Pituitary adenomas (PAs) are intracranial tumors, deriving from anterior pituitary cells. Previously, expression of non-metastasis-23 (NM23) gene has been shown to correlate with the progression of PAs. In this study, we aim to determine whether there is association between specific NM23 polymorphisms and invasive pituitary adenoma (IPA). METHODS Genotypes of rs2302254 and rs16949649 of NM23 were identified in the peripheral venous blood of patients by PCR-RLFP. Next, the correlation between specific genotypes of rs2302254 and rs16949649 and risk of IPA was investigated. Finally, the correlations between NM23 polymorphisms and tumor size, Ki67 LI and recurrence of IPA were analyzed with 3 to 24 months follow-up for the enrolled patients. RESULTS We observed that the TT genotype at rs16949649 correlated closely with a high risk of IPA, while CC and CT genotypes reduced the risk of IPA. CC genotype at rs2302254 increased the risk of IPA, while CT and TT genotypes reduced the risk of IPA. Trs16949649Crs2302254 haplotype of NM23 was found to be a high-risk haplotype for IPA. TT genotype at rs16949649 and CC genotype at rs2302254 were associated with higher rates of tumors larger than 20 mm, Ki67 LI and tumor recurrence. CONCLUSION Taken together, the present study provides evidence that NM23 polymorphisms are closely associated with the incidence and recurrence of IPA. Specifically, TT genotype at rs16949649 and CC genotype at rs2302254 are risk factors of IPA. NM23 polymorphisms could therefore be used as a reference for clinical diagnosis and prognosis of IPA.

Abstract
Although pituitary adenomas (PAs) are regarded as benign neoplasm, efficient postoperative management of PAs, especially invasive PAs, is still a major challenge for neurosurgeons. Thus, in order to verify the effect of postoperative surveillance alone for invasive PAs and identify helpful predictive factors of relapse after initial surgery, a series of 107 cases of surgically gross-totally resected invasive PAs were retrospectively investigated. With regarded to pituitary function, the preoperative incidence of hypothyroidism was higher than that of hypoadrenocorticism and hypogonadism (66.4% vs. 31.8% and 29.9%; p < 0.001). Tumors extended into sphenoid sinus or cavernous sinus may be less likely to develop hypoadrenocorticism or hypogonadism. Postoperative relapse was found in 35 cases (32.7%) during a median follow-up of 27 months. The overall relapse rates were 12.3, 28.9 and 38.4% at 1, 3 and 5 years, respectively. Tumor size was the exclusive independent risk factor for relapse. Higher relapse rates presented in large invasive PAs (more than 3.45 cm) were 24.5, 48.9 and 59.2% at 1, 3 and 5 years, respectively. In conclusion, preoperative larger tumors shared significantly higher risk of relapse after initial surgical total resection. Due to the relatively high relapse rate, close surveillance should be executed in strict rotation in postoperative management of gross-totally resected invasive PAs. Moreover, special attention should be payed to tumors with diameter of more than 3.45 cm for more than half of them relapsed in 5 years.
