Long-term blood glucose control via glucose-activated transcriptional regulation of insulin analogue in type 1 diabetes mice.

Aim: To achieve glucose-activated transcriptional regulation of insulin analogue in skeletal muscle of T1D mice, thereby controlling blood glucose levels and preventing or mitigating diabetes-related complications.

Materials And Methods: We developed the GANIT (Glucose-Activated NFAT-regulated INSA-F Transcription) system, an innovative platform building upon the previously established intramuscular plasmid DNA (pDNA) delivery and expression system. In the GANIT system, skeletal muscle cells are genetically engineered to endogenously produce the insulin analogue INSA-F (Insulin Aspart with Furin cleavage sites).

Glucose-Activated Switch Regulating Insulin Analog Secretion Enables Long-term Precise Glucose Control in Mice With Type 1 Diabetes.

Unlabelled: Genetic modification of non-β-cells to produce insulin is a promising therapeutic strategy for type 1 diabetes; however, it is associated with issues, including biosafety and precise regulation of insulin supply. In this study, a glucose-activated single-strand insulin analog (SIA) switch (GAIS) was constructed to achieve repeatable pulse activation of SIA secretion in response to hyperglycemia. In the GAIS system, the conditional aggregation domain-furin cleavage sequence-SIA fusion protein was encoded by the intramuscularly delivered plasmid and temporarily kept in the endoplasmic reticulum (ER) because it binds to the GRP78 protein; then, upon hyperglycemia, the SIA was released and secreted into the blood.

KIF4A knockdown inhibits tumor progression and promotes chemo-sensitivity via induction of P21 in lung cancer cells.

KIF4A has been demonstrated to play a crucial function in the pathogenesis of a broad number of tumors and have close association with PI3K/AKT pathway. The aim of this study was to explore the potential function of KIF4A in lung cancer progression by targeting PI3K/AKT pathway and P21 combination with doxorubicin. A549 cell lines were transfected with siRNA against KIF4A and negative control siRNA (si-NC).

Prolonged control of insulin-dependent diabetes via intramuscular expression of plasmid-encoded single-strand insulin analogue.

Daily insulin injection is necessary for the treatment of the insulin-dependent diabetes. However, the process is painful and inconvenient. Accordingly, we have made exploratory efforts to establish an alternative method for continuous insulin supply via intramuscular injection of a designed plasmid encoding the single-strand insulin analogue (SIA), which provides safe, effective and prolonged control of insulin-dependent diabetes.

F-FDG-PET/CT-guided intensity-modulated radiotherapy for 42 FIGO III/IV ovarian cancer: A retrospective study.

The aim of the present study was to evaluate the curative effect of fludeoxyglucose-positron emission tomography/computed tomography (F-FDG-PET/CT)-guided intensity-modulated radiotherapy (IMRT) for 42 patients with International Federation of Gynecology and Obstetrics (FIGO) stage III/IV ovarian cancer. Between January 2012 and December 2015, 42 patients with FIGO stage III/IV ovarian cancer who were treated with F-FDG-PET/CT-guided IMRT at the Department of Radiation Oncology were analyzed. A total of 21 patients who exhibited recurrence following surgery and 11 patients who were unable to tolerate or rejected surgery received 5-10 cycles of chemotherapy only.

Curative effect of stereotactic body radiotherapy for unresectable massive primary liver cancer.

The aim of this study was to evaluate the curative effect of gamma knife stereotactic body radiotherapy (SBRT) for unresectable massive primary liver cancer. A total of 69 patients with unresectable massive (>10 cm) primary liver cancer who were treated by SBRT at the Department of Radiation Oncology of the 323 Hospital of People's Liberation Army (Xi'an, China) between October, 2006 and October, 2010, were analyzed. According to the Union for International Cancer Control TNM staging guidelines, the patients were graded as stage T1 (n=8), T2 (n=12), T3 (n=21) and T4 (n=28).

Curative effect of stereotactic body radiotherapy on hepatic hilar carcinoma.

This study was conducted to investigate the effect of stereotactic body radiotherapy (SBRT) on hepatic hilar tumors. Between October, 2006 and October, 2012, we analyzed 63 unresectable hepatic hilar tumors that were treated by SBRT at the Department of Radiation Oncology, 323 Hospital of the People's Liberation Army, Xi'an, China. The patients received a total radiation dose of 45 Gy (range, 44-48 Gy) with a dose fractionation of 3-6 Gy/fx, administered for a total of 9-12 times, 2-5 times/week.
