Description:
10-Deacetyl-7-xylosyl paclitaxel is a Paclitaxel derivative with improved pharmacological features and higher water solubility. It induced mitotic cell cycle arrest and apoptosis as measured by flow cytometry, DNA laddering, and transmission electron microscopy. Moreover, it had no effect on the expression of CD95 and NF-kappaB proteins, indicating that apoptosis was induced through the mitochondrial-dependent pathway in PC-3 cells.

1.Augmentation of response to nab-paclitaxel by inhibition of insulin-like growth factor (IGF) signaling in preclinical pancreatic cancer models.
Awasthi N1,2, Scire E3, Monahan S1, Grojean M4, Zhang E1, Schwarz MA5,2, Schwarz RE1,6. Oncotarget. 2016 Apr 26. doi: 10.18632/oncotarget.9029. [Epub ahead of print]
Nab-paclitaxel has recently shown greater efficacy in pancreatic ductal adenocarcinoma (PDAC). Insulin like growth factor (IGF) signaling proteins are frequently overexpressed in PDAC and correlate with aggressive tumor phenotype and poor prognosis. We evaluated the improvement in nab-paclitaxel response by addition of BMS-754807, a small molecule inhibitor of IGF-1R/IR signaling, in preclinical PDAC models. In subcutaneous xenografts using AsPC-1 cells, average net tumor growth in different therapy groups was 248.3 mm3 in controls, 42.4 mm3 after nab-paclitaxel (p = 0.002), 93.3 mm3 after BMS-754807 (p = 0.01) and 1.9 mm3 after nab-paclitaxel plus BMS-754807 (p = 0.0002). In subcutaneous xenografts using Panc-1 cells, average net tumor growth in different therapy groups was: 294.3 mm3 in controls, 23.1 mm3 after nab-paclitaxel (p = 0.002), 118.2 mm3 after BMS-754807 (p = 0.02) and -87.4 mm3 (tumor regression) after nab-paclitaxel plus BMS-754807 (p = 0.
2.Outcomes of Patients With Surgically and Pathologically Staged IIIA-IVB Pure Endometrioid-type Endometrial Cancer: A Taiwanese Gynecology Oncology Group (TGOG-2005) Retrospective Cohort Study (A STROBE-Compliant Article).

In the management of patients with advanced-stage pure endometrioid-type endometrial cancer (E-EC), such as positive lymph nodes (stage III) or stage IV, treatment options are severely limited. This article aims to investigate the outcome of women with FIGO III-IV E-EC (based on FIGO 2009 system).The retrospective cohort study, based on the Taiwanese Gynecologic Oncology Group (TGOG-2005), enrolled patients undergoing staging surgery to have a pathologically confirmed FIGO III-IV E-EC from 22-member hospitals between 1991 and 2010.This cohort included 541 patients (stage III, n = 464; stage IV, n = 77). Five-year overall survival (OS) was 70.4%. Median progression-free survival (PFS) was 43 months (range 0-258 months) and median OS was 52 months (range 1-258 months). Multivariate analysis showed that FIGO stage, >1/2 myometrial invasion (hazard ratio [HR] 1.53, 95% confidence interval [CI] 1.12-2.09; P = 0.007), histological grade 3 (HR 2.
3.Modified chitosan thermosensitive hydrogel enables sustained and efficient anti-tumor therapy via intratumoral injection.
Jiang Y1, Meng X1, Wu Z2, Qi X3. Carbohydr Polym. 2016 Jun 25;144:245-53. doi: 10.1016/j.carbpol.2016.02.059. Epub 2016 Feb 23.
Thermosensitive in situ hydrogels are potential candidates to achieve intratumoral administration, nevertheless their weak mechanical strength always lead to serious drug leakage and burst. Herein, we developed a chitosan based thermosensitive hydrogel of high mechanical strength, which was modified by glutaraldehyde (GA) and polyvinyl alcohol (PVA), for intratumoral delivery of paclitaxel (PTX). The modified hydrogel system could achieve sol-gel transition at 35.79±0.4°C and exhibit a 7.03-fold greater mechanical strength compared with simple chitosan hydrogel. Moreover, the drug release of PTX loaded modified hydrogel in PBS (pH 7.4) was found to be extended to 13 days. After intratumoral administration in mice bearing H22 tumors, PTX-loaded modified hydrogels exhibited a 3.72-fold greater antitumor activity compared with Taxol(®). Overall, these modified hydrogel systems demonstrated to be a promising way to achieve efficient sustained release and enhanced anti-tumor therapy efficiency of anticancer drugs through in situ tumor injectable administration.
4.Up-regulation of KIF14 is a predictor of poor survival and a novel prognostic biomarker of chemoresistance to paclitaxel treatment in cervical cancer.
Wang W1, Shi Y1, Li J2, Cui W2, Yang B3. Biosci Rep. 2016 Apr 5;36(2). pii: e00315. Print 2016 Apr.
Kinesin family member 14 (KIF14) is a member of kinesin family proteins which have been found to be dysregulated in various cancer types. However, the expression of KIF14 and its potential prognostic significance have not been investigated in cervical cancer. Real-time PCR was performed to assess the expression levels of KIF14 in 47 pairs of cervical cancer tissues and their matched normal tissues from patients who had not been exposed to chemotherapy as well as tissue samples from 57 cervical cancer patients who are sensitive to paclitaxel treatment and 53 patients who are resistant. The association between KIF14 expression levels in tissue and clinicopathological features or chemosensitivity was examined. Kaplan-Meier analysis and Cox proportional hazards model were applied to assess the correlation between KIF14 expression levels and overall survival (OS) of cervical cancer patients. KIF14 expression levels were significantly increased in cervical cancer tissues compared with matched non-cancerous tissues and it was higher in tissues of patients who are chemoresistant compared with those who are chemosensitive.
