Abstract
Cold atmospheric plasma (CAP) holds promise as a cancer-specific treatment that selectively kills various types of malignant cells. We used CAP-activated media (PAM) to utilize a range of the generated short- and long-lived reactive species. Specific antibodies, small molecule inhibitors and CRISPR/Cas9 gene-editing approaches showed an essential role for receptor tyrosine kinases, especially epidermal growth factor (EGF) receptor, in mediating triple negative breast cancer (TNBC) cell responses to PAM. EGF also dramatically enhanced the sensitivity and specificity of PAM against TNBC cells. Site-specific phospho-EGFR analysis, signal transduction inhibitors and reconstitution of EGFR-depleted cells with EGFR-mutants confirmed the role of phospho-tyrosines 992/1173 and phospholipase C gamma signaling in up-regulating levels of reactive oxygen species above the apoptotic threshold. EGF-triggered EGFR activation enhanced the sensitivity and selectivity of PAM effects on TNBC cells. The proposed approach based on the synergy of CAP and EGFR-targeted therapy may provide new opportunities to improve the clinical management of TNBC.

Abstract
Proline, glutamate, and leucine-rich protein 1 (PELP1) are involved in several cancers, but little is known about PELP1 in lung cancer. In this study, PELP1 expression was evaluated in 305 lung cancer (NSCLC) specimens to explore the role of PELP1 in lung cancer. After silencing PELP1, the proliferation, migration, invasion of tumor cells, PELP1 in relation to cell cycle and signaling pathways were evaluated, and whole-genome exons were analyzed. PELP1 is overexpressed in lung cancer, PELP1 expression correlated with squamous carcinoma, smoking, and wild-type EGFR status (all Ps<0.001) but associated with lung cancer-specific survival (P > 0.05). Silencing significantly inhibited lung cancer cell proliferation, migration, and invasion (P < 0.05) and promoted high sensitivity of lung cancer cells to tyrosine kinase inhibitor (TKI) gefitinib. PELP1-silenced cells showed downregulated phosphorylated MAPK, cyclinD1, CDK2, and upregulated RB (P < 0.05) but no change in AKT. In PELP1-silenced lung cancer cells, 140 genes were upregulated, and 143 genes were downregulated. Furthermore, the number of T regulatory cell was higher in lung adenocarcinoma with pelp1 high-expression and pelp1 expression was negatively correlated with CD274 (PDL-1) and CTLA4. Therefore, PELP1 plays an important role in the malignant behavior of NSCLC and could be a potential therapeutic target.

Abstract
Objective To investigate the effect of estrogen on the progression of post-traumatic osteoarthritis (PTOA) in mice and its possible mechanism. Methods Twelve-week-old ICR mice were divided into Group A (female control group), group B (ovariectomized(OVX) group), group C (OVX group supplemented with estrogen), and group D (male group) by destabilization of the medial meniscus (DMM)or sham operation. Safranin O staining was performed at 8 weeks and 12 weeks after operation, and the degree of articular cartilage lesion was evaluated using Mankin score. Twelve weeks after the operation, tissue sections were stained to analyze the matrix metalloproteinase 13(MMP13), phosphorylated epidermal growth factor receptor (p-EGFR) expression and apoptosis of chondrocytes. Results Decreased estrogen can significantly increase the weight of mice in female mice. The degree of cartilage damage in the knee joint on the DMM side of female mice was significantly severer than that on the Sham side. The DMM side also showed higher MMP13 expression and increased apoptotic chondrocytes. The degree of cartilage damage in the knee joint on the DMM side of female mice was significantly reduced after estrogen supplementation, and cartilage damage in the knee joint on the DMM side of female mice was less serious than that of male mice. As estrogen levels decreased, the severity of cartilage erosion in the knee joint on the DMM side was aggravated, and p-EGFR expression in the cartilage surface was also higher in female mice contrast to that in male mice. However, minimal changes in p-EGFR expression in the cartilage surface of bilateral knee joints of male mice were observe. Conclusion Estrogen has a regulatory effect on PTOA and its inhibits the expression of p-EGFR in cartilage on the knee joint surface and has a protective effect on articular cartilage in female mice.

Abstract
Resistance to epidermal growth factor receptor-tyrosin kinase inhibitors (TKIs, e.g. icotinib) remains a major clinical challenge. Non-small cell lung cancer patients with wild-type EGFR and/or K-RAS mutation are primary resistance to EGFR-TKIs. Berberine has been found to have potent anticancer activities via distinct molecular mechanism. In this study, we sought to investigate the therapeutic utility of BBR in combination with icotinib to overcome icotinib resistance in NSCLC cells, and explore the molecular mechanism of synergism of icotinib and BBR to EGFR-resistant NSCLC cells. We used the two EGFR-resistant NSCLC cell lines H460 and H1299 for testing the inhibitory effect of icotinib and/or BBR on them. Moreover, xenograft mouse model was applied for assessing the anti-tumor activities of BBR and icotinib in combination. Results showed that BBR and icotinib have a synergistic inhibitory effect on H460 and H1299 cells through induction of autophagic cell death and apoptosis. Accordingly, the anti-cancer effect of BBR plus icotinib was further confirmed in the NSCLC xenograft mouse models. Combination of BBR and icotinib significantly inhibited the protein expression and the activity of EGFR by inducing autophagic EGFR degradation. BBR plus icotinib resulted in intracellular ROS accumulation, which could mediated autophagy and apoptosis and involved in the suppression of cell migration and invasion. In conclusions, combination application of BBR and icotinib could be an effective strategy to overcome icotinib resistance in the treatment of NSCLC.

Abstract
Dry eye (DE) is a chronic, multifactorial ocular surface disease associated with visual disturbance, tear film instability, hyperosmolarity, ocular surface inflammation and damage. Effective intervention is necessary to control this disease. In this study we topically applied α-melanocyte stimulating hormone (α-MSH) on the ocular surface of scopolamine-induced DE rats and found that it promoted tear secretion, reduced tear breakup time and fluorescein sodium staining and increased the number of conjunctival goblet cells. To investigate the mechanism, protein array was conducted, which showed that α-MSH exerted its effects via epithelial growth factor receptor (EGFR) in the JAK-STAT signaling pathway. Furthermore, in vitro experiments showed that α-MSH protected human corneal epithelial cells (hCECs) by maintaining their migration ability and viability and decreasing apoptosis. However, blockade of EGFR abolished these protective effects. Moreover, α-MSH decreased the level of autophagy in benzalkonium chloride (BAC)-stressed hCECs via EGFR. These results demonstrated that α-MSH ameliorated lesions and restored ocular surface functions by upregulating EGFR expression.

Abstract
Epithelial growth factor receptor (EGFR) directed tyrosine kinase inhibitor (TKI) treatment is the standard approach in patients with advanced, EGFR‐mutated non‐small cell lung cancer (NSCLC). Although benefit/risk ratio is favorable for these TKI and side effects are manageable in the vast majority of patients, severe and even life‐threatening side effects have been reported. TKI‐induced interstitial lung disease (ILD) has been reported for single cases in modest severity, predominantly in EGFR‐TKI pretreated patients. Here, we report a case of successful stabilization of a life‐threatening ILD in a de novo T790M mutated NSCLC during first‐line treatment with osimertinib. As osimertinib will be used more often in many EGFR‐positive NSCLC patients in the future, this potentially life‐threatening side effect should receive special attention, especially in first‐line treatment.

Abstract
The expression of epidermal growth factor (EGF) is increased during liver fibrogenesis, and EGF receptor (EGFR) antagonist could attenuate liver fibrosis. Since EGFR is highly expressed by hepatocytes and cholangiocytes in cirrhotic liver, whether hepatic stellate cells express EGFR in response to EGF still needs exploration. Although EGFR antagonist could attenuate liver fibrosis, many ligands with EGF-like domains, besides EGF, can function through EGFR. Whether specifically blocking EGF could attenuate bile duct ligation (BDL)-induced liver fibrosis has not been revealed. BDL induced biliary infarcts and matrix deposition in mouse liver, and EGFR was expressed and phosphorylated by α-smooth muscle actin (αSMA)-positive myofibroblasts. LX-2 cells expressed EGFR, and these receptors were phosphorylated in the in vitro culture system. Growth curve and cell cycle analysis revealed that EGF could enhance cell proliferation of LX-2 cells. In addition, administration of EGF antibodies markedly reduced the EGF level in serum and the deposition of extracellular matrix in the liver of BDL mice when compared to IgG administration. Administration of EGF antibodies also reduced the phosphorylation of EGFR and the percentage of Ki-67-positive or PCNA-positive liver myofibroblasts of BDL mice when compared to IgG administration. Therefore, activated hepatic stellate cells express EGFR, thus being responsive to EGF signal, and administration of EGF antibodies could attenuate liver fibrosis by restricting the proliferation of myofibroblasts.

Abstract
Abnormal tensional cellular homeostasis is now considered a hallmark of cancer. Despite this, the origin of this abnormality remains unclear. In this work, we investigated the role of tissue transglutaminase 2 (TG2, also known as TGM2), a protein associated with poor prognosis and increased metastatic potential, and its relationship to the EGF receptor in the regulation of the mechanical state of tumor cells. Remarkably, we observed a TG2-mediated modulation of focal adhesion composition as well as stiffness-induced FAK activation, which was linked with a distinctive increase in cell contractility, in experiments using both pharmacological and shRNA-based approaches. Additionally, the increased contractility could be reproduced in non-malignant cells upon TG2 expression. Moreover, the increased cell contractility mediated by TG2 was largely due to the loss of EGFR-mediated inhibition of cell contractility. These findings establish intracellular TG2 as a regulator of cellular tensional homeostasis and suggest the existence of signaling switches that control the contribution of growth factor receptors in determining the mechanical state of a cell.

Abstract
PURPOSE This study aims to understand the effects and long-term survival of 1st generation epithelial growth factor receptor tyrosine kinase inhibitors(EGFR-TKI)or platinum-based chemotherapy as first-line therapy in advanced lung adenocarcinoma patients with uncommon EGFR mutations. PATIENTS AND METHODS Specimens from 4276 advanced (IIIB/IV) patients were diagnosed with lung adenocarcinoma and underwent EGFR gene detection at the Affiliated Cancer Hospital of Zhengzhou University. The clinic characteristics, survival outcomes data, treatment outcomes and data of subsequent therapies after first-line treatment were collected of patients with uncommon EGFR mutations. The results were compared with common EGFR mutations. RESULTS For patients with uncommon EGFR mutations, EGFR-TKIs or platinum-based chemotherapy as first-line therapy, showed no difference in objective response rate (ORR 33% vs 27.1% P = 0.499) and disease control rate (DCR 76.5% vs 87.5%, P = 0.194). EGFR-TKIs showed a superior progression-free survival than chemotherapy (median PFS, 7.2 vs 4.9 mt, HR = 0.604; P = 0.0088). Interestingly, compared with chemotherapy, we found that overall survival (median OS, 14.3 vs 20.7 mts, HR = 1.759; P = 0.0336) was significantly worse in patients with EGFR-TKIs. Multivariate analysis showed that extra metastases (HR = 2.240, P = 0.001) and smoking history (HR = 2.048, P = 0.013) were independent prognostic factors for OS in lung adenocarcinoma patients with EGFR uncommon mutations. CONCLUSIONS Compared with chemotherapy, use of the 1st generation of EGFR-TKIs as first-line therapy can improve the short-term efficacy of patients with EGFR uncommon mutations advanced lung adenocarcinoma, but platinum-based chemotherapy showed a longer overall survival.

Abstract
OBJECTIVE Anti-epithelial growth factor receptor (EGFR) antibodies cetuximab (Cmab) and panitumumab (Pmab) have shown survival benefit for metastatic colorectal cancer (mCRC) patients. This study aimed to compare Pmab and Cmab according to the interval between bevacizumab discontinuation and anti-EGFR antibody initiation (bevacizumab-free interval; BFI). METHODS We retrospectively evaluated mCRC patients who received Cmab or Pmab in combination with irinotecan at two institutions. Inclusion criteria were histologically confirmed mCRC, with KRAS exon 2 wild-type tumor, refractory or intolerant to fluoropyrimidines, oxali platin, and irinotecan. RESULTS One-hundred-seventy-eight patients fulfilled the eligibility criteria. Among them, there was no significant difference in overall survival (OS) and progression-free survival (PFS) between the Pmab (n = 44) and Cmab groups (n = 134). Of 132 patients with BFI < 6 months, the median OS was 13.3 and 11.5 months in the Pmab (n = 39) and Cmab (n = 93) groups, respectively (p = 0.043). The median PFS was 5.8 and 4.9 months in the Pmab and Cmab groups, respectively (p = 0.055). Multivariate analysis for OS confirmed the superiority of Pmab. CONCLUSION Pmab showed more favorable outcomes in patients treated with bevacizumab within the last 6 months. The interval between prior bevacizumab and subsequent anti-EGFR therapy may be useful for determining the optimal anti-EGFR therapy.

Abstract
Colorectal cancer (CRC) is a common malignant tumor of the digestive system. At present, traditional chemotherapy is often combined with targeted drugs to treat patients with metastatic colon cancer, in order to increase the response rate, prolong the progression free survival and overall survival, and improve the quality of life of patients. In this paper, we describe the molecular targets for targeted therapy of CRC and their distribution in CRC, which include vascular endothelial growth factor, epidermal growth factor receptor, cyclooxygenase-2, matrix metalloproteinase, receptor tyrosine kinase, PD-1/PD-L1, RAS, BRAF and so on. In addition, we review current targeted therapies for CRC, including antibody drugs, small molecule targeted drugs, fusion proteins, immune therapy and so on. This paper will provide a reference for individualized treatment of CRC.

Abstract
Mucus hypersecretion is a prominent mechanism in airway inflammation. Muc5ac is a major component of mucus and can be activated by reactive oxygen species (ROS). Peroxiredoxin 6 (Prdx6) highly expresses in airway epithelium and protects the airway from oxidative stress. In this study, we investigated the roles of Prdx6 in lipopolysaccharide (LPS)-induced mucin production in mice. We found that the levels of H2O2 and the Muc5ac mRNA were significantly increased in Prdx6 (-/-) mice compared to those in C57BL/6J mice after LPS instillation, which were markedly inhibited by epithelial growth factor receptor (EGFR) inhibitor Elrotinib. In vitro studies showed that mRNA levels of Prdx6 were decreased while H2O2 and Muc5ac were increased in a dose-dependent manner after LPS exposure, with significant increase in Prdx6 knockdown bronchial epithelial cells compared with those in normal epithelial cells. LPS-induced Muc5ac release was significantly inhibited by EGFR inhibitor, p38 inhibitor and JNK inhibitor, but not ERK1/2 inhibitor, indicating that the H2O2-EGFR-MAPK pathway is likely involved in the responses. This study indicated that Prdx6 decreased LPS-induced Muc5ac increase and played important roles in mucin hypersecretion after LPS exposure.

Abstract
Barrett’s esophagus (BE), a premalignant condition to Barrett’s adenocarcinoma (BAC), is closely associated with chronic inflammation due to gastro-esophageal reflux. Caudal type homeobox 2 (CDX2), a representative marker of BE, is increased during the metaplastic and neoplastic transformation of BE. Nitric oxide (NO) has been proposed to be a crucial mediator of Barrett’s carcinogenesis. We previously demonstrated that CDX2 might be induced directly under stimulation of large amounts of NO generated around the gastro-esophageal junction (GEJ) by activating epithelial growth factor receptor in a ligand-independent manner. Thus, we reviewed recent developments on the role of NO in Barrett’s carcinogenesis. Notably, recent studies have reported that microbial communities in the distal esophagus are significantly different among groups with a normal esophagus, reflux esophagitis, BE or BAC, despite there being no difference in the bacterial quantity. Considering that microorganism components can be one of the major sources of large amounts of NO, these studies suggest that the bacterial composition in the distal esophagus might play an important role in regulating NO production during the carcinogenic process. Controlling an inflammatory reaction due to gastro-esophageal reflux or bacterial composition around the GEJ might help prevent the progression of Barrett’s carcinogenesis by inhibiting NO production.

Abstract
Protein Kinase C Delta (PRKCD) has been highlighted among disrupted pathways in corticotroph adenomas. PRKCD is expressed at low level in human corticotroph adenomas and controls cell cycle in vitro. Therefore, PRKCD may play an important role in the development/progression of corticotroph adenomas, warranting further studies to understand the role of PRKCD and related pathways in restraining pituitary cell growth. We evaluated PRKCD role in influencing cell behavior in terms of cell viability, hormone expression and protein expression profile, by silencing PRKCD in AtT-20/D16v-F2 cells. PRKCD silencing increases cell viability, enhances hormone expression and induces morphological changes associated with deregulation of adhesion molecules. PRKCD silencing is associated with an increase in Epithelial Growth Factor Receptor (EGFR) expression, a marker of tumor aggressive behavior, and sensitivity to anti-EGFR molecules. PRKCD might restrain corticotroph adenoma cells from acquiring an aggressive behavior, candidating PRKCD as a possible molecular target for the treatment of corticotroph adenomas.

Abstract
Increasing evidence of a critical role played by the bronchial epithelium in airway homeostasis is opening new therapeutic avenues. Its unique situation at the interface with the environment suggests that the subtle regulation orchestrated by the epithelium between tolerance and specific immune response might be impaired in asthma. Airway mucus is acting as a physical and a biological fluid between the environment and the epithelium, synergistically moved by the cilia. In asthma, excessive mucus production is a hallmark of airway remodeling. Since many years we tried to therapeutically target mucus hypersecretion, but actually this option is still not achieved. The present review discusses the dynamic processes regulating airway mucus production. Airway inflammation is central in current asthma management. Understanding of how the airway epithelium influences the TH2 paradigm in response to deleterious agents is improving. The multiple receptors expressed by the airway epithelium are the transducers of the biological signals induced by various invasive agents to develop the most adapted response. Airway remodeling is observed in severe chronic airway diseases and may result from ongoing disturbance of signal transduction and epithelial renewal. Chronic airway diseases such as asthma will require assessment of these epithelial abnormalities to identify phenotypic characteristics associated with predicting a clinical benefit for epithelial-directed therapies.
