Abstract
Fibroblast growth factor 2 (FGF-2) is not only an angiogenic factor, but also a mitogen for epidermal keratinocytes. FGF-2 has been shown to be positively immunoreactive in the basal layer of psoriatic lesions. In previous work, we used the Escherichia coli (E. coli) expression system to biosynthesize a biologically active anti-FGF-2 nanobody (Nb) screened by phage display technology, but the low yield limited its clinical application. In this study, we aimed to increase the yield of anti-FGF-2 Nb, and evaluate its therapeutic potential for psoriasis by inhibiting FGF-2-mediated mitogenic signaling in psoriatic epidermal keratinocytes. We demonstrated a 16-fold improvement in the yield of anti-FGF-2 Nb produced in the Pichia pastoris (P. pastoris) compared to the E. coli expression system. In vitro, the FGF-2-induced HaCaT cell model (FHCM) was established to mimic the key feature of keratinocyte overproliferation in psoriasis. Anti-FGF-2 Nb was able to effectively inhibit the proliferation and migration of FHCM. In vivo, anti-FGF-2 Nb attenuated the severity of imiquimod (IMQ)-induced psoriatic lesions in mice, and also improved the inflammatory microenvironment by inhibiting the secretion of inflammatory cytokines (IL-1β, IL-6, IL-23, and TNF-α), chemokines (CXCL1 and CCL20), and neutrophil infiltration in skin lesions. These were mainly related to the suppression of FGF-2-mediated mitogenic signaling in psoriatic keratinocytes. In conclusion, we have improved the production of anti-FGF-2 Nb and demonstrated the modality of attenuating the abnormal proliferative behavior of psoriatic keratinocytes by inhibiting FGF-2-mediated mitogenic signaling, which offers the possibility of treating psoriasis.

Abstract
Paclitaxel, a compound naturally occurring in yew, is a commonly used drug for the treatment of different types of cancer. Unfortunately, frequent cancer cell resistance significantly decreases its anticancer effectivity. The main reason for the resistance development is the paclitaxel-induced phenomenon of cytoprotective autophagy occurring by different mechanisms of action in dependence on a cell type and possibly even leading to metastases. Paclitaxel also induces autophagy in cancer stem cells, which greatly contributes to tumor resistance development. Paclitaxel anticancer effectivity can be predicted by the presence of several autophagy-related molecular markers, such as tumor necrosis factor superfamily member 13 in triple-negative breast cancer or cystine/glutamate transporter encoded by the SLC7A11 gene in ovarian cancer. Nevertheless, the undesired effects of paclitaxel-induced autophagy can be eliminated by paclitaxel co-administration with autophagy inhibitors, such as chloroquine. Interestingly, in certain cases, it is worthy of potentiating autophagy by paclitaxel combination with autophagy inducers, for instance, apatinib. A modern strategy in anticancer research is also to encapsulate chemotherapeutics into nanoparticle carriers or develop their novel derivatives with improved anticancer properties. Hence, in this review article, we summarize not only the current knowledge of paclitaxel-induced autophagy and its role in cancer resistance but mainly the possible drug combinations based on paclitaxel and their administration in nanoparticle-based formulations as well as paclitaxel analogs with autophagy-modulating properties.

Abstract
Autophagy is a highly conserved metabolic process with a cytoprotective function. Autophagy is involved in cancer, infection, immunity, and inflammation and may be a potential therapeutic target. Increasing evidence has revealed that autophagy has primary implications for esophageal cancer, including its initiation, progression, tumor microenvironment (TME) modification, diagnosis, and treatment. Notably, autophagy displayed excellent application potential in radiotherapy combined with immunotherapy. Radiotherapy combined with immunotherapy is a new potential therapeutic strategy for cancers, including esophageal cancer. Autophagy modulators can work as adjuvant enhancers in radiotherapy or immunotherapy of cancers. This review highlights the most recent data related to the role of autophagy regulation in esophageal cancer.

Abstract
OBJECTIVES Despite remarkable advances in the treatment of oesophageal cancer (OC), the role of antiepidermal growth factor receptor (anti-EGFR) agents in treating OC remains controversial. Herein, a systematic review and meta-analysis were conducted to elucidate the efficacy and safety of anti-EGFR agents in patients with OC. DESIGN Meta-analysis of randomised controlled trials (RCTs) identified by searching the PubMed, Embase, Web of Science, ClinicalTrials.gov, Cochrane Library, Chinese Biology Medicine, China National Knowledge Infrastructure and Wanfang Data Knowledge Service Platform databases from inception to December 2019. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. SETTING RCTs from any country and healthcare setting. PARTICIPANTS Patients with OC. INTERVENTIONS Combination therapy with anti-EGFR agents and conventional treatments versus conventional treatments alone in patients with OC. PRIMARY AND SECONDARY OUTCOME MEASURES Overall survival (OS) and progression-free survival (PFS) were primary outcome measures, and objective response rate (ORR), disease control rate (DCR) and treatment toxicities were secondary outcome measures. RESULTS In total, 25 RCTs comprising 3406 patients with OC were included. Overall, anti-EGFR treatment significantly improved the OS (HR: 0.81, 95% CI 0.74 to 0.89, p<0.00001), ORR (relative risk (RR): 1.33, 95% CI 1.16 to 1.52, p<0.0001) and DCR (RR: 1.22, 95% CI 1.11 to 1.34, p<0.0001) but not PFS (HR: 0.91, 95% CI 0.76 to 1.08, p=0.26). Anti-EGFR treatment was significantly associated with higher incidences of myelosuppression, diarrhoea, acne-like rash and hypomagnesaemia. CONCLUSIONS Overall, anti-EGFR agents have positive effects on OS, the ORR and DCR in OC. However, considering the high incidence of adverse effects, such as myelosuppression, diarrhoea, acne-like rashes and hypomagnesaemia, careful monitoring of patients with OC is recommended during anti-EGFR treatment. TRIAL REGISTRATION NUMBER CRD42020169230.

Abstract
Objective To investigate the safety and efficacy of nimotuzumab combined with radiotherapy for elderly patients with non-resectable esophageal carcinoma (EC). Methods Eligible patients were aged 70 years or older and had treatment-naïve, histologically proven inoperable locally advanced EC. Enrolled patients received radiotherapy with a total dose of 50−60 Gy in 25−30 fractions, concurrent with weekly infusion of nimotuzumab. The primary end point was the rate of more than grade 3 toxicities. Results From June 2011 to July 2016, 46 patients with stage II−IV EC with a median age of 76.5 years were enrolled. There were 10, 28 and 8 patients with stage II, III and IV disease, respectively. The common acute toxicities included esophagitis (grade 1−2, 75.4%; grade 3, 8.7%), pneumonitis (grade 1, 4.3%; grade 2, 6.5%; grade 3, 2.2%), leukopenia (grade 1−2, 60.9%; grade 3−4, 4.4%), gastrointestinal reaction (grade 1−2, 17.3%; grade 3, 2.2%), thrombocytopenia (grade 1−2, 21.7%; grade 3, 2.2%), and radiothermitis (grade 1−2, 39.2%). The incidence of grade 3−4 adverse effects was 17.4%. No grade 5 toxicities were observed. Clinical complete response, partial response, stable disease, and progressive disease were observed in 1 (2.2%), 31 (67.4%), 12 (26.1%), and 2 (4.3%) patients, respectively. The median overall survival (OS) and progression-free survival (PFS) were 17 and 10 months, respectively. The 2-, 3-, and 5-year OS and PFS rates were 30.4%, 21.7%, 19.6%, and 26.1%, 19.6%, 19.6%, respectively. Conclusions Nimotuzumab combined with radiotherapy is a safe and effective therapy for elderly patients who are not surgical candidates. Further studies are warranted to confirm its therapeutic effects in elderly EC patients.

Abstract
Although cisplatin is one of the most common antineoplastic drug, its successful utilisation in cancer treatment is limited by the drug resistance. Multiple attempts have been made to find potential cisplatin chemosensitisers which would overcome cancer cells resistance thus improving antineoplastic efficacy. Autophagy modulation has become an important area of interest regarding the aforementioned topic. Autophagy is a highly conservative cellular self-digestive process implicated in response to multiple environmental stressors. The high basal level of autophagy is a common phenomenon in cisplatin-resistant cancer cells which is thought to grant survival benefit. However current evidence supports the role of autophagy in either promoting or limiting carcinogenesis depending on the context. This encourages the search of substances modulating the process to alleviate cisplatin resistance. Such a strategy encompasses not only simple autophagy inhibition but also harnessing the process to induce autophagy-dependent cell death. In this paper, we briefly describe the mechanism of cisplatin resistance with a special emphasis on autophagy and we give an extensive literature review of potential substances with cisplatin chemosensitising properties related to autophagy modulation.

Abstract
Human papillomavirus (HPV) 16 E6 has been proved to increase the radiosensitivity and lead to the EGFR overexpression in cervical cancer cells. In this study, to investigate the inhibition of nimotuzumab-mediated EGFR blockade combined with radiotherapy, we established a C33A cervical squamous cell line overexpressed HPV16-E6 and a nude mouse model bearing these cell lines. The CCK-8 assay was used to detect the effects of various treatments on the proliferation of C33A cells. Flow cytometry was used to detect the rates of apoptosis and cell cycle arrest. Gene transcription and protein expression were detected by quantitative real-time polymerase chain reaction (qRT-PCR) and western blot, respectively. Immunohistochemical staining was used to evaluate protein expression in tumor tissue. We revealed that E6-overexpressing C33A cells grew faster and were more sensitive to radiotherapy than control cells in vitro and in vivo. The expression levels of EGFR, as well as those of downstream signaling molecules AKT and ERK 1/2, were significantly upregulated in C33A cells that overexpressed E6. We observed that nimotuzumab combined with radiotherapy could enhance the inhibition of C33A cell growth induced by E6, both in vitro and in vivo. We also observed enhanced effect after combination on G2/M cell cycle arrest and apoptosis in E6-overexpressing C33A cells. Furthermore, the combined therapy of nimotuzumab and radiation remarkably reduced the protein expression levels of EGFR, AKT, ERK 1/2 in vitro, and in vivo. In conclusion, HPV16 E6 expression is positively correlated with levels of EGFR, AKT, and ERK 1/2 protein expression. The combined treatment with nimotuzumab and radiotherapy to enhance radiosensitivity in E6-positive cervical squamous cell carcinoma was related to enhanced G2/M cell cycle arrest and caspase-related apoptosis.

Abstract
Esophageal cancer is among the most aggressive forms of human malignancy with five-year survival rates of <20%. Autophagy is an evolutionarily conserved catabolic process that degrades and recycles damaged organelles and misfolded proteins to maintain cellular homeostasis. While alterations in autophagy have been associated with carcinogenesis across tissues, cell type- and context-dependent roles for autophagy have been reported. Herein, we review the current knowledge related to autophagy in esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC), the two most common subtypes of esophageal malignancy. We explore roles for autophagy in the development and progression of ESCC and EAC. We then continue to discuss molecular markers of autophagy as they relate to esophageal patient outcomes. Finally, we summarize current literature examining roles for autophagy in ESCC and EAC response to therapy and discuss considerations for the potential use of autophagy inhibitors as experimental therapeutics that may improve patient outcomes in esophageal cancer.

Abstract
Esophageal squamous cell carcinoma (ESCC) is amongst the most aggressive human malignancies, representing a significant health burden worldwide. Autophagy is an evolutionarily conserved catabolic process that degrades and recycles damaged organelles and misfolded proteins to maintain cellular homeostasis. Alterations in autophagy are associated with cancer pathogenesis, including ESCC; however, the functional role of autophagy in ESCC remains elusive. Here, we discuss the clinical relevance of autophagy effectors in ESCC and review current knowledge regarding the molecular mechanisms through which autophagy contributes to ESCC. We highlight the cytoprotective role of autophagy in ESCC and discuss autophagy inhibitors as novel experimental therapeutics to potentiate the effects of anti-cancer therapies and/or to overcome therapeutic resistance in ESCC.

Nimotuzumab is a blocking monoclonal antibody against epidermal growth factor receptor (EGFR). However, little is known about the safety and preliminary efficacy of nimotuzumab combined with concurrent chemoradiotherapy in locally advanced NPC patients. A total of 42 patients diagnosed between 2011 and 2013 were enrolled. Our results demonstrated 38 patients had a complete response (90.5%), 4 patients had a partial response (9.5%). And no patients had progressive disease at early treatment response evaluation, giving an ORR of 100%. The 2-year local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS) and overall survival (OS) were 96.4%, 93.1% and 96.6% respectively. The most common adverse events were mucositis (19 patients), hematology toxicity (14 patients) with 6 and 3 cases of grade 3/4 toxicity respectively. Skin rash was not developed in our 43 patients. Thus, nimotuzumab combined with concurrent chemoradiotherapy showed encouraging outcomes in the treatment of locally advanced nasopharyngeal carcinoma, without accumulation of toxicity and well-tolerated.

Abstract
Autophagy is an evolutionarily conserved cell survival program that degrades dysfunctional organelles and misfolded or long-lived proteins through the formation of lysosomes. Basal autophagy helps to maintain cellular homeostasis, while additional autophagy can be induced under cellular stress conditions. Autophagy has shown to be involved in a variety of diseases, such as inflammation, autoimmune diseases, degeneration, and cancer. We review the relevance of autophagy to the diagnosis and clinical management of esophageal diseases with the following questions in mind. What is autophagy and can/should we detect it in routine pathology specimens? What is the role of autophagy in gastroesophageal reflux disease/inflammatory esophageal disease? What role may autophagy play in the interaction between pro- and antiapoptotic pathways in esophageal malignancies and treatment?

Abstract
Nimotuzumab is a humanized IgG1 monoclonal antibody against the EGFR extracellular domain that has been evaluated in solid tumors as a single agent or in combination with chemotherapy and radiation. Cervical cancer patients who are refractory or progressive to first-line chemotherapy have a dismal prognosis, and no second- or third-line chemotherapy is considered standard. This pilot trial aimed to evaluate the efficacy and safety of nimotuzumab in 17 patients with pre-treated advanced refractory or progressive cervical cancer. Nimotuzumab was administered weekly at 200 mg/m(2) as single agent for 4 weeks (induction phase), then concurrent with 6 21-day cycles of gemcitabine (800 mg/m(2)) or cisplatin (50 mg/m(2)) for 18 weeks (concurrent phase) and then once every 2 weeks (maintenance phase). Nimotuzumab could be continued beyond disease progression. Seventeen patients were accrued and evaluated for safety and efficacy. The median number of nimotuzumab applications was 20 (5-96). The median number of chemotherapy cycles administered was 6 (1-6). No toxicity occurred during induction and maintenance phases (single agent nimotuzumab). In the concurrent phase, grade 3 toxicity events observed were leucopenia, anemia and diarrhea in 11.7%, 5.8% and 11.7% respectively. No complete or partial responses were observed. The stable disease (SD) rate was 35%. The median PFS and OS rates were 163 days (95% CI, 104 to 222), and 299 days (95% IC, 177 to 421) respectively. Nimotuzumab is well tolerated and may have a role in the treatment of advanced cervical cancer.

Abstract
Esophageal adenocarcinoma (EAC) is characterized by rapidly increasing incidence and mortality rates and poor survival. Efficacious preventive and treatment options are urgently needed. An increasing number of pharmacologic agents targeting cancer cell death via autophagy mechanisms are being evaluated in hopes of circumventing apoptotic and therapeutic resistance. We report for the first time, loss of Beclin-1, a key mediator of autophagy, was significantly linked to prognostic factors in EAC. Specifically, Beclin-1 expression loss occurred in 49.0% of EAC patients versus 4.8% of controls. There was a significant inverse correlation between loss of Beclin-1 with histologic grade and tumor stage supporting a tumor suppressive role for Beclin-1. Autophagy modulation linked to cell death was examined in EAC cell lines following treatment with a proanthocyanidin-rich cranberry extract, C-PAC, and the commonly used autophagy inducer, rapamycin. C-PAC induced Beclin-1-independent autophagy in EAC cells characterized by reduced phosphorylation at serine 15 and 93, and significant cell death induction. In contrast, rapamycin-induced autophagy resulted in concomitant, increases in total Beclin-1 levels as well as Beclin-1-phosphorylation in a cell line specific manner, leading to long-term cell survival. Furthermore, autophagic LC3-II was induced by C-PAC following siRNA suppression of Beclin-1 in EAC cells. Together these data support a prognostic role of Beclin-1 in EAC with evidence that Beclin-dependent autophagy induction is agent specific. Future studies are necessary to fully interrogate the role autophagy plays in the progression of normal tissue to EAC and how specific agents targeting autophagic mechanisms can be efficaciously applied for cancer prevention or treatment. © 2015 Wiley Periodicals, Inc.

Abstract
OBJECTIVE To explore the clinical effects of nimotuzumab combined with chemotherapy in the treatment of late gastric cancer. METHODS A total of 34 reoccurrence or metastatic patients with late stage gastric cancer who were confirmed by histopathology and/or cytology were selected and randomly divided into observational and control groups, of 17 cases each. Patients in the control group were treated with the standard DCF plan, while patients in observational group additionally received nimotuzumab. The short-term and long-term efficacy and adverse reactions in the 2 groups were followed. RESULTS The objective response rate (ORR) and disease control rate (DCR) were 64.7% (11/17) and 82.4% (14/17) in observational group and 25.0%(4/16) and 37.5%(6/16) in the control group(ORR and DCR between 2 groups, χ2=5.2412, P=0.0221 and χ2=6.9453, P=0.0084). The median progression-free survival (PFS) time and median overall survival (OS) time were 6.50 months and 12.50 months in observational group and 4.50 months and 8.25 months in the control group (P=0.0212; P=0.0255). The main toxic and side effects in the 2 groups were reduced leukocytes and hemoglobin, gastrointestinal reactions and hair loss and these were relieved after symptomatic treatment and nutrition support therapy. There were no differences in the occurrence of toxic and side effects between the 2 groups. CONCLUSIONS Nimotuzumab combined with DCF plan is effective in treating late stage gastric cancer. A larger scale study is now warranted for confirmation of the findings.

Abstract
Background The epidermal growth factor receptor (EGFR) signaling pathway plays a significant role in radiation resistance. There is evidence that EGFR nuclear translocation is associated with DNA double-strand breaks (DSB) repair. Nimotuzumab has shown the effect of radiosensitization in various cancer cells, but little is known about the relationship between nimotuzumab and EGFR nuclear translocation in non-small cell lung cancer (NSCLC) cell lines. In this study, we selected two NSCLC cell lines, namely, H292 (with high EGFR expression) and H1975 (with low EGFR expression) and explored the mechanisms underlying radiation sensitivity. Methods MTT assay, clonogenic survival assay, and flow cytometry were performed separately to test cell viability, radiation sensitivity, cell cycle distribution, and apoptosis. Protein γ-H2AX, DNA-PK/p-DNA-PK, and EGFR/p-EGFR expression were further compared both in the cytoplasm and the nucleus with the western blot. Results Nimotuzumab reduced the viability of H292 cells and sensitized H292 cells to ionizing radiation. The radiation sensitivity enhancement ratio (SER) was 1.304 and 1.092 for H292 and H1975 cells, respectively. H292 cells after nimotuzumab administration were arrested at the G0/G1 phase in response to radiation. Apoptosis was without statistical significance in both cell lines. γ-H2AX formation in the combination group (nimotuzumab and radiation) increased both in the cytoplasm and the nucleus along with the decreased expression of nuclear EGFR/p-EGFR and p-DNA-PK in H292 cells (P<0.05) that was more significant than that in H1975 cells. Conclusion Our research revealed a possible mechanism to explain the radiosensitivity in H292 cells. Nimotuzumab decreased the radiation-induced activation of DNA-PK by blocking EGFR nuclear translocation and impairing DNA DSB repair, thus enhancing radiosensitivity in H292 cells. Because these results represent early research, the matters of how γ-H2AX and DNA-PK dynamically change simultaneously with nuclear EGFR and the best time to administer nimotuzumab will require further exploration.

Abstract
BACKGROUND Nimotuzumab is a humanized IgG1 type monoclonal antibody targeting epidermal growth factor receptor, and can enhance chemosensitivity and radiosensitivity of certain cancers. The aim of this study is to investigate the effects of nimotuzumab on the chemosensitivities of PC9 human lung adenocarcinoma cells to common chemtherapeutic drugs including ciaplatin, gemcitabine, paclitaxel, pemetrexed and vinorelbine, and to elucidate possible mechanisms. METHODS PC9 human lung adenocarcinoma cell line was used in the study. Cell proliferation was determined by WST-1 assay and cell apoptosis was detected by TUNEL assay. Cell cycle distribution was analyzed by DNA analysis with FACS. Tublin and microfilaments were observed by immunofluorescence staining. RESULTS Nimotuzumab significantly enhanced the chemosensitivity of PC9 cells to paclitaxel. Cell proliferation was inhibited significantly (P<0.05) and cell apoptosis rate was higher in nimotuzumab combined with low dose paclitaxel (0.05 μg/mL) group (P=0.013). G2/M arrest was increased significantly by nimotuzumab combined with paclitaxel group (P<0.05). Nimotuzumab caused aggregation of tublin and microfilaments into well organized microtubules. CONCLUSIONS Nimotuzumab enhanced the chemosensitivity of PC9 cell to paclitaxel by enhancing G2/M arrest and aggregation of tublin and microfilaments. Therefore, Nimotuzumab combined with taxane drugs could be a potential effective regimen in non-small cell lung cancer.
