ABSTRACT

Prefoldin (PFDN), a hexameric chaperone complex, is crucial for the correct folding of nascent proteins. PFDN5, a subunit of PFDN, also known as MM-1, plays an essential role in regulating cell migration and senescence. Emerging evidences suggest that PFDN-5 deletion or mutation significantly contributes to the initiation and progression of multiple cancers and the prognosis of patients. In this paper, recent researches on the biological underpinnings of PFDN-5 and its anti-cancer prospect are reviewed, aiming to provide a novel potential therapeutic target for the treatment of malignancies.

ABSTRACT

Objective To evaluate the clinical effects and safety of paclitaxel liposome or gemcitabine combined with cisplatin in elderly patients with advanced lung squamous cell cancer. Methods A total of 52 elderly patients with advanced lung squamous cell cancer in Kunshan First People's Hospital from January 2012 to October 2016 who received paclitaxel liposome with cisplatin (n=24) or gemcitabine with cisplatin(n = 28) were analyzed retrospectively. The patients received at least 2 cycles of chemotherapy, 2-6 cycles in total. CT was rechecked every 2 cycles. The clinical effects and adverse reactions were evaluated by National Cancer Institute Response Evaluation Criteria in Solid Tumors (NCI RECIST) and NCI Common Terminology Criteria for Adverse Events (NCI CTCAE). Results The objective response rate (ORR) and the disease control rate(DCR)in paclitaxel liposome group and in gemcitabine group had a lot in common [ORR:29.2 %(7/24)vs.32.1 %(9/28),χ2=0.054,P =0.817;DCR:70.8 %(17/24)vs.71.4 %(20/28),χ2=0.002,P =0.962]. The median progression-free survival(PFS) time in gemcitabine group was longer than that in paclitaxel liposome group (5.7 months vs. 5.4 months, χ2= 0.466, P = 0.495). One-year survival rate in gemcitabine group (37.0 %) was higher than that in paclitaxel liposome group (34.8 %) and there was no statistically significant difference (χ 2= 0.027, P = 0.869). However, hematologic adverse reactions in paclitaxel liposome group were lower than those in gemcitabine group (P< 0.05). Conclusion The effect of paclitaxel liposomes combined with cisplatin for treatment of elderly patients with advanced lung squamous cell carcinoma is not inferior to gemcitabine combined with cisplatin, which has less adverse reactions and may be recommended as the first-line chemotherapy for the patients.

ABSTRACT

Radiotherapy is a major local treatment for cervical cancer.However, local uncontrollability due to radioresistance is still common.Therefore, the prediction of radiosensitivity is quite beneficial to develop an optimal treatment strategy for individual patients.Multiple factors could influence the radiosensitivity of cells, and p53 status is one of them.The upstream or downstream molecules of p53 could also be regulated to affect the radiosensitivity of cervical cancer.The aim of the review is to analyze the difference in p53 status between different types of cervical cancer and to discuss how p53 regulates the response to radiotherapy.

ABSTRACT

Objective To analyze the therapeutic effect of the radical operation for gastric cancer in elderly patients and to investigate relevant factors affecting the efficacy Methods 216 cases of elderly patients with gastric cancer were divided into two groups:radical distal-and proximal-gastrectomy group (n=108,each).The therapeutic effect in the near future,intraoperative and postoperative recovery,numbers of lymph nodes resection as well as factors affecting the long-term survival rate were compared between two groups.Results The radical distal-versus proximal-gastrectomy group showed that the mean operation time was (241.8 ± 40.2) min vs.(244.7 ± 39.7)min,blood loss was(299.5 ± 114.9) ml vs.(273.8-± 121.4) ml,the number of lymph node dissection was(28.4± 9.4) vs.(27.7 ± 9.1) particles,the complication rate was[14/108 (13.0%)] vs.[15/108 (14.0 %)],3-year survival rate was (46.9 %) vs.(47.5 %),without statistically significant differences (all P > 0.05).Multiple regression analysis showed that TNM stage (OR =1.536),lymph node metastasis(OR =0.739),cancer infiltration depth (OR =1.534) and chemotherapy regimens (OR =1.337)are risk factors for the postoperative 3-year survival rate.Conclusions Surgical treatment of elderly patients with gastric cancer is significantly effective,TNM stage,lymph node metastasis,depth of invasion,tumor size and the chemotherapy regimens are closely associated with the life quality of patients.

ABSTRACT

Objective To value the clinical efficacy and toxicity of S-1 compared to gemcitabine combined with S-1 in treatment of patients with advanced pancreatic cancer.Methods From January 2011 to December 2013,the data of 46 patients with advanced pancreatic cancer were analyzed retrospectively,including 24 patients receiving S-1 alone (group A) and 22 patients who received gemcitabine combined with S-1 (group B).The results were evaluated by objective response rate (ORR),disease control rate (DCR),survival time and safety.Results In group A the ORR was 20.8 % (5/24),DCR was 66.7 % (16/24),median progression-free survival was 4.8 months,median overall survival was 9.6 months,and 1 year survival was 12.5 %.In group B the ORR was 27.3 % (6/22),DCR was 72.7 % (16/22),median progression-free survival was 5.9 months,median overall survival was 10.3 months,and 1 year survival was 22.7 %.There was no significant difference between the two groups (P > 0.05).The incidence rates of leukopenia,neutropenia and thrombopenia in group A were significantly lower than those in group B (P < 0.05).Conclusion S-1 alone and gemcitabine combined with S-1 have similar effects in the treatment of advanced pancreatic cancer,but the toxicity of S-1 is mild and tolerable.

ABSTRACT

Objective To investigate the mechanism of anti-breast cancer cell proliferation induced by doxorubicin (DOX).Methods AMP-Activated Protein Kinase (AMPK) activator AICAR,AMPK siRNA,AMPK inhibitor compound C(AMPKi) and doxorubicin treated MCF-7 cells at different time points; AMPK,acetyl CoA carboxylase (ACC),p38 activation were detected by Western blot.MTT was used as cell viability assay. Results Doxorubicin-induced activation of AMPK, AMPK agonist (AICAR)or in combination with doxorubicin activated AMPK and increased MCF-7 cell proliferation rate [the difference of cell viability between group AICAR+DOX(17.7±1.6 ) % and group DOX(71.4±1.8 ) % was significant(P<0.001)].After AMPKi or AMPK siRNA and doxorubicin combined administration, P-AMPK and P-ACC expression was significantly decreased,the level of p38 was not affected,and MCF-7 cell proliferation inhibition rate decreased [the cell viability of group AMPKi+DOX(72.7±1.8 ) % vs group DOX(96.3±1.7 ) %,P<0.001 ;group AMPK siRNA +DOX( 76.9±2.2 ) % vs group scramble siRNA+DOX(95.9±1.8) %,P<0.001].Conclusion AMPK is involved in doxorubicin-induced anti-breast cancer cell proliferation.
