OBJECTIVETo investigate the glycolytic phenotype of SHG44 human glioma cells under hypoxic conditions and the association between cell proliferation and apoptosis and the metabolic status.

METHODSAn in vitro hypoxic cell model was established in SHG44 cells using CoCl2. Real-time PCR and Western blotting were used to assess the expressions of hypoxia-inducible factor-1α (HIF-1α) and the enzymes involved in glycolysis including PDK1, PKM2, and LDHA. Intracellular ATP levels were measured by bioluminescence assay to assess the energy metabolic status of SHG44 cells. The viability and apoptosis of the cells were examined using MTT assay and flow cytometry, respectively.

RESULTSThe cells in hypoxic culture showed obviously increased expressions of HIF-1α, LDHA, PDK1, and PKM2 at both the mRNA and protein levels as compared to those in normal cell culture. Hypoxia of the cells also resulted in a lowered cell proliferative activity and an increased apoptosis rate with lowered intracellular ATP concentrations and elevated mitochondrial membrane potential.

CONCLUSIONHypoxia can induce a glycolytic phenotype of tumor cells. The sensitivity of tumor cells to hypoxia-induced cell death is directly correlated with their metabolic status.

Objective: To discuss the etiology, pathogenesis, clinical manifestation, diagnosis and therapy of sphenoid wing dysplasia(SWD) associated with neurofibromatosis type Ⅰ(NF-Ⅰ). Methods: We retrospectively reviewed its clinical manifestations, imaging, surgical treatment, complications and postoperative outcome of one NF-Ⅰ patient with SWD. Results: A 14 years-old girl presented with pulsating exophthalmos, loss of vision and café au lait spots. Radiological studies showed right-side orbital enlargement and complete absence of the greater wing of the sphenoid. Titanium mesh was tailored intraoperatively to close the defect as a barrier between the orbital cavity and the cranium and then covered by periosteum.The patient developed postoperative infectious which was controlled by after antibiotic treatment and proper drainage. Proptosis improved significantly after surgery within a month. Ocular pulsation subsided and clinical symptoms improved at 28-month follow-up. Conclusions Sphenoid greater wing dysplasia associated with neurofibromatosis type Ⅰ is a rare inherited autosomal dominant disorders. The treatment should be customized to each patient. Titanium mesh reconstruction is patients with symptomatic sphenoid dysplasia. It can correct the proptosis and pulsating exophthalmos without the risk of bone resorption and recurrence.However, high risk of infection is associated with the procedure.

Pheochromocytomas and paragangliomas(PPGLs)cause symptoms by altering the circulation levels of catecholamines and peptide hormones.Currently,the diagnosis of PPGLs relies on diagnostic imaging and the detection of catecholamines.In this study,we used ultra-performance liquid chromatography(UPLC)/quadrupole time-of-flight mass spectrometry(Q-TOF MS)analysis to identify and measure the perioperative differential metabolites in the plasma of adrenal pheochromocytoma patients.We identified differentially expressed genes by comparing the transcriptomic data of pheochromocytoma with the normal adrenal medulla.Through conducting two steps of metabolomics analysis,we identified 111 differential metabolites between the healthy group and the patient group,among which 53 metabolites were validated.By integrating the information of differential metabolites and differentially expressed genes,we inferred that the cysteine-methionine,pyrimidine,and tyrosine metabolism pathways were the three main metabolic pathways altered by the neoplasm.The analysis of transcription levels revealed that the tyrosine and cysteine-methionine metabolism pathways were downregulated in pheochromocytoma,whereas the pyrimidine pathway showed no significant difference.Finally,we developed an optimized diagnostic model of two metabolites,L-dihydroorotic acid and vanylglycol.Our results for these metabolites suggest that they may serve as potential clinical biomarkers and can be used to supplement and improve the diagnosis of pheochromocytoma.
