Many studies are based on the hypothesis that recurrence and drug resistance in lung carcinoma are due to a subpopulation of cancer stem-like cells (CSLCs) in solid tumors. Therefore it is crucial to screen for and recognize lung CSLCs. In this study, we stimulated non-small cell lung cancer (NSCLC) A549 cells to display stem cell-like characteristics using a combination of five small molecule compounds. The putative A549 stem cells activated an important CSLC marker, CD133 protein, as well multiple CSLC-related genes including ATP-binding cassette transporter G2 (ABCG2), C-X-C chemokine receptor type 4 (CXCR4), NESTIN, and BMI1...

Targeting protein for Xenopus kinesin-like protein 2 (TPX2) has been demonstrated to be associated with the tumorigenesis of many cancers. In the present study, we investigated the role and preliminary mechanism of TPX2 in the resistance of lung squamous carcinoma to radiation therapy. The results showed that SK-MES-1R and NCI-H226R cells were more resistant to X-ray irradiation than the parental cells (SK-MES-1 and NCI-H226). Moreover, TPX2 was upregulated in the radioresistant cells compared with the parental cells...

Immunotherapy, especially checkpoint inhibitors such as anti-PD1 and anti-PDL1 antibodies, has changed the standard of care and the prognosis of melanoma, but also more recently of lung cancer, renal cancer and Hodgkin lymphoma. Results of preliminary studies in head and neck squamous cell carcinoma (HNSCC) as well as in less frequent tumors of the region, such as nasopharyngeal carcinoma and high grade salivary gland carcinoma, are also promising. Indeed, in a recent phase 3 study, the PD1 inhibitor nivolumab has recently demonstrated a significant improvement in overall survival for platin-resistant recurrent and/or metastatic HNSCC...

PURPOSE: The majority of non-small cell lung cancer (NSCLC) patients presents with an advanced-stage disease and, consequently, exhibits a poor overall survival rate. We aimed to assess changes in plasma miR-9, miR-16, miR-205 and miR-486 levels and their potential as biomarkers for the diagnosis and monitoring of NSCLC patients. METHODS: Plasma was collected from 50 healthy donors and from NSCLC patients before surgery (n = 61), 1 month after surgery (n = 37) and 1 year after surgery (n = 14)...

Metastatic brain tumor occasionally results in multiple cerebral hemorrhages. Here, we report a case of metastatic brain tumor complicated by multiple repeated cerebral hemorrhages. An 80-year-old man with a history of removal of lung cancer was admitted to our hospital because of disturbed consciousness following headache. A brain CT revealed a mass lesion of 40-mm diameter in the left cerebellum and a mass lesion of 2-mm diameter in the right temporal lobe. The cerebellar mass lesion showed homogeneous iso-density, indicating a subacute phase hemorrhage...

Introduction Carcinomas of the papilla of Vater make up a heterogeneous group of tumours arising from different types of epithelium. Regional lymph nodes, liver and lungs are the primary sites of metastatic progression of these tumours. Case presentation We present a patient with an abdominal incision site metastasis of low-grade (mixed type) adenocarcinoma of the papilla of Vater one year after pylorus-preserving pancreaticoduodenectomy. Implantation metastasis of low-grade ampullary carcinoma in the laparotomy wound after open Whipple's procedure is unusual...

The management of bronchopleural fistulas can be challenging. The initial treatment is usually conservative, but operative intervention with transposition of vascularized pedicled flaps may be required in refractory cases. We present the case of a 67-year-old man with stage IIIa squamous cell carcinoma of the lung who underwent a lower and middle bilobectomy after receiving neoadjuvant chemoradiation. His postoperative course was complicated by empyema and a bronchopleural fistula. Because of difficulty accessing the fistula, endobronchial-guided vascularized tissue flaps were successfully used to close the fistula...

Nanomedicine to overcome both systemic and tumor tissue barriers ideally should have a transformable size and surface, maintaining a certain size and negative surface charge for prolonged circulation, while reducing to a smaller size and switching to a positive surface charge for efficient penetration to and retention in the interstitial space throughout the tumor tissue. However, the design of such size and charge dual-transformable nanomedicine is rarely reported. Here, the design of a shell-stacked nanoparticle (SNP) is reported, which can undergo remarkable size reduction from about 145 to 40 nm, and surface charge reversal from -7...

Increasing evidence supports that the dysregulation of microRNA expression plays an important role in the process of tumor occurrence and development. Studies have found that mir-125a-5p expression was downregulated in a variety of tumors, but the effects and mechanism of mir-125a-5p in lung cancer are still unclear. The aim of this study is to detect the expression of mir-125a-5p in lung cancer tissues and lung cancer cell lines and to explore the effects of mir-125a-5p on the biological characteristics of lung cancer cells; thus, this study aims to provide new methods and new strategies for the treatment of lung cancer...

The mechanism of dsRNA-induced gene activation (RNAa) is being gradually unveiled. The plentiful evidence that it existed in mammalian species other than human demonstrated that dsRNA-mediated RNAa is a conservative phenomenon. Simultaneously, accumulating evidence suggested that microRNAs could activate gene expression by targeting promoter. Nevertheless, it is ambiguous whether microRNA-induced gene activation in different human cells is a common phenomenon. The study we performed verified that miR-1236-3p (miR-1236) and miR-370-5p can activate p21 expression in bladder cancer (BCa) T24, EJ cells, and non-small-cell lung carcinoma A549 cells, while in hepatocellular HepG2 cells both microRNAs cannot effectively induce the expression of P21(WAF1/CIP1) (p21)...

Abnormal expression of microRNAs has been reported to regulate gene expression and cancer cell growth, invasion, and migration. Recently, upregulation of hsa-miR-1285 was demonstrated in bronchoalveolar lavage fluid samples from patients with lung cancer and downregulation in plasma level of stage-I lung cancer patients. However, the function and the underlying mechanism of miR-1285 in non-small-cell lung carcinoma have not been elucidated. In this study, we found that miR-1285-5p, the mature form of miR-1285, was significantly upregulated in human non-small-cell lung carcinoma cell lines A549 and SK-MES-1...

Increasing evidence suggests that the glutathione peroxidase 2 may actually play important roles in tumorigenesis and progression in various human cancers such as colorectal carcinomas and lung adenocarcinomas. However, the role of glutathione peroxidase 2 in gastric carcinoma remains to be determined. In this study, the expression and prognostic significance of glutathione peroxidase 2 in gastric carcinoma were investigated and the well-known prognostic factor Ki-67 labeling index was also assessed as positive control...

Human lung squamous cell carcinoma is a deadly cancer for which present therapeutic strategies are inadequate. And traditional chemotherapy results in severe systemic toxicity. Compounds from living organisms often exert a biological activity, triggering several targets, which may be useful for the improvement of novel pharmaceuticals. Aloe-emodin (AE), a well-known natural compound, is a primary component of anthraquinones in Aloe vera and exhibits anti-proliferative and apoptotic effects on various tumor cells...

Mohamed Kazamel, Paula Province Warren
The early development of nerve conduction studies (NCS) and electromyography (EMG) was linked to the discovery of electricity. This relationship had been concluded by observing the effect of applying electricity to the body of an animal and discovering that nerves and muscles themselves could produce electricity. We attempt to review the historical evolution of NCS and EMG over the last three centuries by reviewing the landmark publications of Galvani, Adrian, Denny-Brown, Larrabee, and Lambert. In 1771, Galvani showed that electrical stimulation of animal muscle tissue produced contraction and, thereby, the concept of animal electricity was born...

Esophageal metastasis from colorectal carcinoma is uncommon, and diagnosis of esophageal metastasis is difficult. We report a case of a 54-year-old woman with postoperative recurrence of rectal cancer metastasizing to the esophagus. She underwent rectectomy and adjuvant chemotherapy with fluorouracil, leucovorin plus oxaliplatin for stage IIIB rectal cancer. Three years later, she presented with dysphagia and cough. Computed tomography showed thickening of the esophagus wall, enlargement of the lymph nodes in the mediastinum and abdomen, and ground-glass opacities in the right lung...

As a treatment for superficial transitional cell carcinoma, Bacillus Calmette-Guerin (BCG) intravesical instillation can rarely cause unpredictable systemic side effects. We describe a patient admitted due to continuous pyrexia and general fatigue. He was previously treated with intravesical BCG. Laboratory data indicated a hepatic disorder, and chest computed tomography revealed extensive bilateral miliary nodules. Transbronchial lung biopsy specimens showed several small noncaseating granulomas. The diagnosis was unsolved on the basis of acid fast staining, polymerase chain reaction and microbiological cultures, so we considered the possibility of BCG side effect-induced granuloma...

Small cell lung cancer (SCLC) is a neuroendocrine tumor, and the median age of onset is about 70 years old. A 20-year-old non-smoking man with known systemic sclerosis presented with discomfort in his left chest. Chest X-ray showed a mass shadow in the left upper zone. A transbronchial lung biopsy revealed small cell carcinoma, and imaging studies reached the diagnosis of extensive disease small cell lung cancer. He had concurrent interstitial lung disease with a non-specific interstitial pneumonia pattern and anti-Scl-70 antibodies...
