A-kinase anchor protein 12 (AKAP12) has been reported to be related to lung squamous cell carcinoma (LUSC) progression. However, its role and molecular mechanisms in LUSC have not been revealed. The mRNA and protein levels of AKAP12 and transcription factor 21 (TCF21) were tested by quantitative real-time PCR and western blot. Cell counting kit 8 assay, EdU assay, flow cytometry, wound healing assay, and transwell assay were used to evaluate cell proliferation, apoptosis, migration, and invasion. Cell glycolysis was measured by testing glucose consumption and lactate production. The interaction between AKAP12 and TCF21 was assessed by ChIP assay and dual-luciferase reporter assay. A mice xenograft model was constructed to explore AKAP12 and TCF21 roles in vivo. Our data showed that AKAP12 was underexpressed in LUSC tissues and cells, and its overexpression inhibited LUSC cell growth, metastasis, and glycolysis. TCF21 had decreased expression in LUSC, which facilitated AKAP12 expression through binding to its promoter region to enhance its transcription. Furthermore, TCF21 increased AKAP12 expression to repress LUSC cell growth, metastasis, and glycolysis. In vivo experiments showed that AKAP12 upregulation reduced LUSC tumorigenesis, and TCF21 knockdown reversed this effect. In conclusion, AKAP12 might be a tumor suppressor in LUSC, which was mediated by TCF21 and could inhibit cell growth, metastasis, and glycolysis to restrain LUSC malignant progression.
BACKGROUND:Advanced cancer (AC) patients experience serious physical and psychological problems with the disease progression. When approaching the end of life, these patients have to cope with not only the bodily illness, but also the spiritual crisis. Conventional psychological treatments reduce distress to a certain extent, but for patients with AC, especially when they face progressive illness and are approaching death, their psychological problems are complex, and no simple solutions are in sight. Therefore, we designed this study to evaluate the efficacy of the combined Naikan therapy (NT) and Morita therapy (MT) on psychological distress and posttraumatic growth in patients with AC. METHOD:One hundred thirty patients newly diagnosed with AC were allocated randomly into treatment (n = 65) and control (n = 65) groups. Patients in the treatment group received combined NT and MT for 7 consecutive weeks, while the control group received normal medical treatments without NT and MT. Patients were assessed before and after the therapies. The primary outcome measures include distress thermometer (DT) and posttraumatic growth, and the secondary outcome measure contains the list of distress problems. RESULTS:At the post-treatment stage, the treatment group displayed a decreased score of psychological distress as compared to that in the control group, which accompanied by a higher post-traumatic growth total score and subscale scores in relationship to others, new possibilities, personal strength, spiritual changes, and appreciation of life. A significant decrease in fear, sleeping difficulty/insomnia, nervousness/anxiety, and loss of appetite was also observed in the treatment group. CONCLUSION:The results proved that the combined Naikan and Morita therapies decreased the psychological distress and improved the posttraumatic growth of the patients with AC.

Zinc (Zn) has antioxidant effect in different types of organs and is closely associated with human health. Endometrial receptivity is one of the most important factors in the embryo implantation and development. However, the regulatory mechanism of Zn in endometrium tissue is still unclear. In the study, we found that plasma Zn level is significantly associated with female infertility, which severely affects female reproductive health. Primary endometrial stromal cells were isolated from female endometrium and cultured in the laboratory. Zn chelator TPEN treatment reduced the expression of stem cell markers CD73, CD90, and CD105 and generated reactive oxygen species in endometrial stromal cells. However, pretreatment of Zn (zinc sulfate) is able to prevent TPEN-induced oxidative stress in vitro. By transcriptional profiling and gene ontology analysis, we found that Zn increased the cellular pluripotency signaling and extracellular matrix-receptor interaction, but reduced autophagy, endocytosis, and the nitrogen metabolism pathway. We further discovered the antioxidant function of Zn through the peroxisome proliferator-activated receptor gamma coactivator 1α/nuclear factor erythroid-2-related factor signaling pathway in endometrial stromal cells. Zn supplementation may open up an effective therapeutic approach for patients with oxidative stress-related endometrial diseases.

Objective To explore the effect of combined Naikan therapy and modified Morita therapy on psychological distress and post traumatic growth in elderly patients with cancer pain.Methods Ninety elderly patients with cancer pain were randomly assigned into two groups;those in the study group(n =45)were given Naikan therapy and modified Morita therapy for 4 weeks and those in the control group (n =45) were given standardized aerodyne treatment and standardized nursing care.All subjects were assessed with the Distress Thermometer and Problem Listand the Post traumatic Growth Inventory before and after Naikan therapy and modified Morita therapy.Results Compared with the control group,the study group was associated with significantly decreased scores of psychological distress(1.8± 0.1 vs.3.9 ± 0.2,t =1.78,P<0.05),emotional problems (1.2 ± 0.4,vs.2.4±0.4,t=1.41,P<0.05)and family problems(1.1±0.1,vs.2.9±0.1,t=1.63,P<0.05).The study group also showed markedly higher scores in posttraumatic growth(66.0± 19.9 vs.45.3± 27.6,t=2.58,P<0.05),relationships to others(34.8±12.1 vs.23.8±12.2,t=1.91,P<0.05),new possibilities(25.2 ± 10.1 vs.13.7± 4.4,t=1.94,P<0.05),personal strength(20.7 ± 10.4 vs.7.6 ± 3.1,t =2.03,P < 0.05),spiritual change (11.6 ± 5.6 vs.5.4 ± 2.7,t =1.26,P < 0.05),and appreciation of life(18.9±6.2 vs.6.1±-2.1,t=1.88,P<0.05) than the control group.Conclusions Naikan therapy and modified Morita therapy can decrease psychological distress and improve post traumatic growth in elderly patients with cancer pain.
High-dose ionizing radiation can cause harmful effects on the cardiovascular system. Notably, endothelial cells are critical targets in radiation-induced damage. γ radiation exerts its biological effects through the radiolysis of water, which further generates ROS and induces lipid peroxidation and DNA damage. The present study aimed to evaluate the potential protective effects of celastrol against γ radiation-induced oxidative stress in human umbilical vein endothelial cells (HUVECs). HUVECs were exposed to γ radiation at different doses with or without celastrol treatment. Cell viability and cytotoxicity, migratory ability, ROS production, lipid peroxidation, oxidative DNA damage and antioxidative enzyme levels were evaluated in HUVECs at 24 h post-irradiation. It was observed that HUVECs exhibited decreased cell viability, increased cytotoxicity and a decreased migratory ability after exposure to 20-Gy γ radiation. Celastrol treatment concentration-dependently reversed these effects. γ irradiation was also demonstrated to increase the production of ROS, enhance lipid peroxidation and oxidative DNA damage and decrease the levels of SOD, catalase, GST and GPx in HUVECs. These detrimental effects were blocked by treatment with celastrol for 24 h. These data suggested that celastrol not only attenuated γ radiation-induced cytotoxicity, but also effectively blocked oxidative stress in HUVECs. As an antioxidant agent, celastrol may have potential protective effects in HUVECs against γ irradiation-induced injury.
Objective Investigate the effect of miR-126 and miR-199 on the cell cycle in breast cancer cells.Methods The expression of miR-126 and miR-199 in breast cancer cells was detected by qRT-PCR assay;the effect of miR-126 and miR-199 expression on the cell cycle of breast cancer cells was detected after miRNA mimics were transfected into breast cancer cell line MDA-MB-231.Results The expression of miR-126 and miR-199 in breast cancer cell line MDA-MB-231 was significantly lower than that of MCF-7 cell line;after transfection of miRNA mimics 48h,the expression of miR-126 and miR-199 in breast cancer cell line MDA-MB-231 was up-regulated,which could promote cell apoptosis and block the cell cycle progression of breast cancer.Conclusion Increasing the expression of miR-126 and miR-199 in breast cancer cells can inhibit tumor cell cycle progression and exert anti-tumor effect.
Objective:To observe the specific killing effect on tumor cells of the spleen cells in mice immunized with three tandem repeats of CEA minigene DNA vaccine pcDNA-triCEA625-667 and to evaluate the safety of the vaccine. Methods: The BALB/c mice were randomly divided into blank vector group ( pcDNA3. 0 ) , haploid vaccine group ( pcDNA-CEA625-667 ) and tandem repeats vaccine group (pcDNA-triCEA625-667). The mice received a total of 4 intramuscular immunization every 10 days once. The changes of body weight,survival state were recorded and the levels of serum ALT and serum creatinine were detected. The specific CTL killing activity of spleen cells in accinated mice on mouse hepatoma cells(H22-CEA+),gastric cancer cells(MFC-CEA+),colorectal cancer cells ( CT26-CEA+) with high expression of CEA and mouse hepatoma cells ( H22-CEA-) without expression of CEA was detected. Results:The two vaccines had strong killing activity on CEA positive liver cancer,gastric cancer and colon cancer cells,and the difference was statistically significant ( P<0. 01 ) compared with the PcDNA3. 0 group. And they had almost no effect on CEA negative tumor cells (H22-CEA-). The killing activity on liver cancer cell(H22-CEA+) and gastric cancer cell(MFC-CEA+) induced by pcDNA-triCEA625-667 was stronger than that induced by pcDNA-triCEA625-667(P<0. 05). The survival status,change of body weight and function of liver and kidney of the mice were not affected by the vaccine. Conclusion:There was no adverse reaction in the course of vaccine immunization. The minigene DNA vaccine derived from CEA can induce tumor specific CTL effect and the immune response level elicited by three tandem repeats of minigene DNA vaccine was superior to that elicited by haploid vaccine.

Objective:To observe the inhibitory effect of haploid vaccine pcDNA-CEA625-667 and three tandem repeats of minigene DNA vaccine pcDNA-triCEA625-667 derived from CEA gene on tumor in mice bearing tumor and the changes of survival time. Methods:The experimental animal model of mouse liver cell carcinoma was established and the mice were immunized with pcDNA-CEA625-667 and three series of DNA vaccine. Some of the mice were treated with normal saline as control group. The growth curve of tumor growth curve was recorded and the effect of vaccine on the survival time of tumor bearing mice was observed. Results:Compared with the normal saline control group,the two vaccines were able to significantly inhibit the tumor size and growth rate ( P<0. 01 ) of CEA positive tumor bearing mice,the inhibition of pcDNA-triCEA625-667 vaccine group was significantly better than the pcDNA-CEA625-667 vaccine group (P<0. 01),while the two were not inhibited tumor growth in CEA negative tumor bearing mice. The average survival time of the pcDNA-CEA625-667 vaccine group was(48. 50±6. 73)d,and there was significant difference (P<0. 01) compared with the saline control group ( 39. 00 ± 6. 64 ) d. The survival time ( 48. 50 ± 6. 73 ) d of the pcDNA-triCEA625-667 vaccine group was significantly higher than that of the normal saline control group and the pcDNA-CEA625-667 vaccine group (P<0. 01). The survival time of CEA negative tumor bearing mice could not be prolonged in the two groups. Conclusion:Either the haploid or the three series of the DNA vaccine,were able to significantly inhibit tumor growth rate (P<0. 01) and significantly prolong the survival time (P<0. 01) of CEA positive tumor bearing mice,but they had no therapeutic effect on CEA negative tumor bearing mice.
