Role of O-GlcNAcylation in cancer biology.

One of the general characteristics of cancer cells is the abnormal increase of O-GlcNAcylation. Recent studies have shown that it affects the basic functions of proteins and regulates multiple phenotypes of cancer cells through key signals and metabolic pathways. O-GlcNAcylation is a covalent linkage between the ß-D-N-acetylglucosamine (GlcNAc) sugar and target protein. It interacts with many other types of post-translational modifications and works together in the whole process of cancer development. For example, it regulates cell activities such as cell signal transduction, transcription, cell division, metabolism and cytoskeleton regulation. In this review, we summarized the general concept of O-GlcNAcylation and its related role in the ten major tumor phenotypes.

CSNK1D is associated with stemness and invasiveness in glioblastoma.

BACKGROUND: Glioblastoma (GBM) is the most common primary malignant brain tumor. It has a poor 5-year survival rate, a high recurrence rate, and few therapeutic options. Exploring the molecular processes underlying the formation and progression of GBM, as well as identifying novel therapeutic targets, is critical for improving GBM therapy and prognosis. METHODS: We extracted primary GSCs (glioblastoma stem cells) from patient-derived samples. Different levels of CSNK1D were evaluated through immunohistochemistry, western blot and real-time PCR assays. A Transwell assay was used to detect invasive ability of cell lines. Tumorsphere formation assay was performed to detect cancer stemness properties. Orthotopic xenograft models were used to evaluate the effect of CSNK1D on GSC tumorigenesis. RESULTS: We found the expression levels of CSNK1D was elevated in GBM tissues compared with normal brain. CSNK1D expression had an increased tendency among WHO grades (G2-G4), and was higher in IDH wildtype group than in mutation group. The prognosis of the CSNK1D high expression group was significantly worse than that of the low expression group. Cox multivariate analysis showed that CSNK1D was also an independent prognostic factor in GBM patients. In primary GBM cells, we observed increased levels of CSNK1D in GSCs compared to non-stem tumor cells (NSTCs). In addition, the change of stemness markers expression and proliferation of GSCs were in coordinate with CSNK1D overexpression or knockdown. Furthermore, CSNK1D could affect the epithelial-mesenchymal transition (EMT) markers and MMPs expression in GSCs. Finally, disruption of CSNK1D expression impairs GSC survival and GBM tumor propagation in orthotopic xenograft models. CONCLUSION: Our results suggest that CSNK1D correlated with GBM prognosis and might influence the stemness and invasiveness of GSCs, which represented a potential therapeutic target in GBM patients.

[Acupuncture for secondary dysmenorrhea of adenomyosis: a prospective case-series study].

OBJECTIVE: To observe the clinical effect of acupuncture by stages on secondary dysmenorrhea of adenomyosis through prospective case-series study. METHODS: A total of 36 cases of adenomyosis patients with moderate-to-severe dysmenorrhea were treated with acupuncture by stages. The acupoints of Diji (SP 8), Sanyinjiao (SP 6), Ciliao (BL 32) and Shiqizhui (EX-B 8) were selected and acupuncture was given once a day during menstrual period; the acupoints of Guanyuan (CV 4), Zigong (EX-CA1), Sanyinjiao (SP 6) and Zusanli (ST 36) ect. were selected and acupuncture was given twice per week during non-menstrual period. All the treatment was given for three menstrual cycles. The visual analogue scale (VAS), Cox menstrual symptom scale (CMSS), Endometriosis Health Profile-5 (EHP-5) scores and the menstrual blood volume of pictorial blood loss assessment chart (PBAC) were observed before treatment and at the 1st, 2nd and 3rd menstrual cycle into treatment. Before treatment and at the 3rd menstrual cycle into treatment, the volume of uterus was measured by transvaginal ultrasound and the correlation among the quality of life, the severity of pain and symptoms was analyzed. RESULTS: The VAS, CMSS and EHP-5 scores at the 1st, 2nd and 3rd menstrual cycle into treatment were lower than those before treatment (P<0.01, P<0.05), and the PBAC scores were reduced but without statistical different (P>0.05). Compared before treatment, at the 1st, 2nd and 3rd menstrual cycle into treatment, the PBAC scores were reduced in patients with PBAC>100 points (P<0.01). Compared between 2nd and 1st menstrual cycle into treatment, between 3rd and 2nd menstrual cycle into treatment, the VAS, CMSS scores were all decreased (P<0.01, P<0.05). There was a significant positive correlation between the severity score of CMSS and EHP-5 at the corresponding time points of the 1st, 2nd and 3rd menstrual cycle into treatment (P<0.01). CONCLUSION: The acupuncture by stages has significant analgesic effect in patients with secondary dysmenorrhea of adenomyosis, and has the advantages of relieving the menstruation-related symptoms, regulating menstrual blood volume and improving the quality of life.

Impact of acupuncture for allergic rhinitis on the activity of the hypothalamus-pituitary-adrenal axis: study protocol for a randomized controlled trial.

BACKGROUND: Patients with moderate and severe persistent allergic rhinitis (AR) have long-term physical and mental stress, leading to dysfunction of the hypothalamus-pituitary-adrenal (HPA) axis, which results in recurrence of AR. Previous research has proved acupuncture can regulate the function of the neuron-endocrine-immune system and contribute to improving the quality of life of patients with AR. This research aims to investigate the mechanism of acupuncture on the HPA axis in patients with moderate or severe persistent AR. METHODS/DESIGN: This randomized controlled trial aims to study the impact of acupuncture on the HPA axis of patients with moderate and severe AR. This research also aims to compare the curative effects of different treatments in three groups of patients: those receiving western medicine, western medicine and conventional acupuncture, or western medicine and mind-regulating acupuncture. We will study the therapeutic effect of acupuncture and the correlation between the changes of therapeutic indexes and experimental indexes after the treatments. Therapeutic indexes include the Visual Analog Scale (VAS) of nasal symptoms and the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) for AR patients; experimental indexes include corticotropin releasing hormone (CRH), adreno-corticotropic hormone (ACTH), cortisol (CORT), interleukin 4 (IL-4), and interferon-γ (IFN-γ). DISCUSSION: The results of this trial will provide evidence for the influence of chronic, long-term, repeated stimulation in patients with moderate and severe persistent AR and the impact of acupuncture on the HPA axis of these patients.

[A Randomized Controlled Clinical Trial of Treatment of Moderate and Severe Persistent Allergic Rhinitis of Spleen Deficiency Pattern by Herbal Cake-partitioned Moxibustion Combined with Rhinocort Nasal Spray].

OBJECTIVE: To evaluate the clinical effect of herbal cake-partitioned moxibustion combined with medication in the treatment of moderate and severe persistent allergic rhinitis (PAR) patients of spleen deficiency pattern. METHODS: Sixty patients with moderate and severe PAR of spleen deficiency pattern were randomized into medication (Rhinocort) group and herbal cake-partitioned moxibustion combined with medication group (combination group, n=30 cases in each). Medicinal cake-partitioned moxibustion was applied to Yintang (GV 29, for about 20 min), Shenque(CV 8, about 50 min), bilateral Zusanli (ST 36, about 40 min)and Hegu(LI 4, about 40 min)once every other day for successive 8 weeks. All the patients received treatment with Rhinocort nasal spray, 2 jets/day for each nostril (64 µg/jet) for 8 weeks. The patients' conditions (symptoms of nasal sufferings, sleeping, sniffle, eye, emotion, etc.) were assessed by visual analogue scale (VAS) and rhino conjunctivitis quality of life questionnaire (RQLQ, 24 items of 7 aspects, 0-6 points/item), respectively. The spleen deficiency syndrome score was determined according to "Guiding Principles for Clinical Research of New Drugs of Chinese Materia Medica" (2002). The therapeutic effect was assessed by referring to "the Diagnostic and Therapeutic Principles and Recommended Schemes for Allergic Rhinitis" (2004). RESULTS: Following the treatment, the scores of VAS, RQLQ, spleen deficiency syndrome were significantly decreased on the 4thand the 8th week of treatment in both groups in comparison with those of their own individual pre-treatment (P<0.05, P<0.01). Four weeks' follow-up survey showed that the VAS score and RQLQ score of the combination group were obviously lower than those of the medication groups (P<0.05), suggesting a better post-effect of moxibustion. Of the two 30 cases in the medication and combination groups, 9 and 9 experienced marked improvement in their symptoms, 16 and 17 were effective, and 5 and 4 ineffective, with the effective rate being 83.3% and 86.7%, respectively. No significant differences were found between the two groups in the VAS and RQLQ scores on the 4th and 8th week during treatment and in the effective rate (P>0.05). CONCLUSION: Herbal cake-partitioned moxibustion combined with hormone (Rhinocort) nasal spray is effective in relieving symptoms of moderate and severe PAR patients of spleen deficiency syndrome, and has a better post-effect.

[Herbal-partitioned moxibustion for moderate to severe persistent allergic rhinitis with spleen-qi deficiency syndrome].

OBJECTIVE: To explore the clinical efficacy of herbal-partitioned moxibustion on moderate and severe persistent allergic rhinitis (AR) with spleen-qi deficiency syndrome. METHODS: With prospective case series study method, forty-seven patients of moderate and severe persistent AR with spleen-qi deficiency syndrome were treated with herbal-partitioned moxibustion at Yintang (GV 29), Shenque (CV 8), Hegu (LI 4) and Zusanli (ST 36), once every two days, three treatments a week, continuously for 8 weeks. The visual analogue scale (VAS), rhinoconjunctivitis quality of life questionnaire (RQLQ) and scores of spleen-qi deficiency syndrome were recorded before treatment, 2 weeks, 4 weeks and 8 weeks into treatment as well as 4 weeks after treatment; in addition, the improvement rate of each index was compared before and after treatment. RESULTS: Compared before treatment, the VAS, RQLQ and scores of spleen-qi deficiency syndrome were significantly reduced 2 weeks, 4 weeks and 8 weeks into treatment as well as 4 weeks after treatment (P<0.05, P<0.01). The efficacy was gradually increased 2 weeks, 4 weeks and 8 weeks into treatment (all P<0.01). On the 8 weeks into treatment, the improved and markedly effective rate was 59.6% (28/47) for VAS, 19.1% (9/47) for RQLQ and 14.9% (7/47) for scores of spleen-qi deficiency syndrome; the total effective rate was all 85.1% (40/47). Compared with 4 weeks after treatment, there was no significant difference (all P>0.05). CONCLUSIONS: The herbal-partitioned moxibustion has superior efficacy for moderate and severe persistent allergic rhinitis with spleen-qi deficiency syndrome.
