PURPOSE: Several non-small cell lung cancer (NSCLC) cases of successful rechallenge with epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) after recovery from gefitinib or erlotinib-induced interstitial lung disease (ILD) have been reported, but it is not clear whether the rechallenge affects the outcome. METHODS: We retrospectively evaluated the difference in the outcome between advanced NCLC patients with active EGFR mutations who received EGFR-TKI rechallenge after recovery from EGFR-TKI-induced ILD and those who did not...

Several receptor tyrosine kinases (RTKs) including EGFR, ALK, and MET have been identified as therapeutic targets in non-small cell lung cancer (NSCLC). Among the downstream pathways of RTKs, the MAPK pathway is particularly important for cancer cell proliferation, differentiation, and survival. In this study, the effects of MEK inhibitors (trametinib and PD0325901) in several NSCLC cell lines with driver gene alterations, especially RTK genes, were tested in vitro using an MTT assay, and a wide range of sensitivities was found...

Neural crest cells (NCC) hold great promise for tissue engineering, however the inability to easily obtain large numbers of NCC is a major factor limiting their use in studies of regenerative medicine. Induced pluripotent stem cells (iPSC) are emerging as a novel candidate that could provide an unlimited source of NCC. In the present study, we examined the potential of neural crest tissue-derived periodontal ligament (PDL) iPSC to differentiate into neural crest-like cells (NCLC) relative to iPSC generated from a non-neural crest derived tissue, foreskin fibroblasts (FF)...

Mesenchymal stem cells (MSCs) are defined as non-hematopoietic, plastic-adherent, self-renewing cells that are capable of tri-lineage differentiation into bone, cartilage or fat in vitro. Thus, MSCs are promising candidates for cell-based medicine. However, classifications of MSCs have been defined retrospectively; moreover, this conventional criterion may be inaccurate due to contamination with other hematopoietic lineage cells. Human MSCs can be enriched by selection for LNGFR and THY-1, and this population may be analogous to murine PDGFRα+ Sca-1+ cells, which are developmentally derived from neural crest cells (NCCs)...

This paper compares two methods to determine the tumor marker progastrin-releasing peptide (ProGRP): as routine assay, the automated time-resolved immunofluorometric assay (TR-IFMA), which allows total ProGRP determination; and the immunocapture liquid chromatography selected reaction monitoring mass spectrometry (LC-SRM-MS) method, which additionally allows isoform differentiation. The investigation included 60 serum samples from patients suffering from various cancer diseases which may cause elevated ProGRP levels (small cell lung carcinoma; SCLC, non-small cell lung carcinoma; NCLC; and medullary thyroid cancer; MTC, as well as some with unspecific diagnosis)...

Nanoscale capillary liquid chromatography (nCLC) and capillary zone electrophoresis (CZE) have been combined with quadrupole mass spectrometry via an electrospray ionization (ESI) interface. These methodologies have been applied to the separation and determination of a variety of sulfonamides. CZE/ESI/MS is the more rapid and sensitive technique, but nCLC/ESI/MS shows promise for the analysis of dilute samples. Ultimately, the two techniques provide complementary methods of analysis. The detection limits of these techniques in the full-scan mode are in the low picomole range...

Urochordates (ascidians) have recently supplanted cephalochordates (amphioxus) as the extant sister taxon of vertebrates. Given that urochordates possess migratory cells that have been classified as 'neural crest-like'- and that cephalochordates lack such cells--this phylogenetic hypothesis may have significant implications with respect to the origin of the neural crest and neural crest-derived skeletal tissues in vertebrates. We present an overview of the genes and gene regulatory network associated with specification of the neural crest in vertebrates...

Similar to embryonic stem cells, induced pluripotent stem (iPS) cells can differentiate into various cell types upon appropriate induction, and thus, may be valuable cell sources for regenerative medicine. However, iPS cells have not been reported to differentiate into odontogenic cells for tooth regeneration. Here we demonstrated that neural crest-like cells (NCLC) derived from mouse iPS cells have the potential to differentiate into odontogenic mesenchymal cells. We developed an efficient culture protocol to induce the differentiation of mouse iPS cells into NCLC...

OBJECTIVE: The purpose of this study was to assess the effectiveness of government health workers as agents for the prevention of disability. DESIGN: A prevention of disability (POD) project for people affected by leprosy was conducted in nine counties of Guizhou Province, Peoples' Republic of China. The project was implemented by government health workers. In accordance with the principles and national criteria of the National Centre for Leprosy Control (NCLC) POD Pilot programme, 1215 people affected by leprosy were selected, followed up and assessed with the use of impairment summary forms through which essential indicators were routinely collected...

Neural crest-like cells (NCLC) that express the HNK-1 antigen and form body pigment cells were previously identified in diverse ascidian species. Here we investigate the embryonic origin, migratory activity, and neural crest related gene expression patterns of NCLC in the ascidian Ciona intestinalis. HNK-1 expression first appeared at about the time of larval hatching in dorsal cells of the posterior trunk. In swimming tadpoles, HNK-1 positive cells began to migrate, and after metamorphosis they were localized in the oral and atrial siphons, branchial gill slits, endostyle, and gut...

This article reviews new insights from ascidians on the ancestry of vertebrate neural crest (NC) cells. Ascidians have neural crest-like cells (NCLC), which migrate from the dorsal midline, express some of the typical NC markers, and develop into body pigment cells. These characters suggest that primordial NC cells were already present in the common ancestor of the vertebrates and urochordates, which have been recently inferred as sister groups. The primitive role of NCLC may have been in pigment cell dispersal and development...

BACKGROUND: Many experienced oncologists have encountered patients with proven non-small cell lung cancer (NCLC) who received modest doses of palliative radiotherapy (RT) and who unexpectedly survived for > 5 years; some were apparently cured. We used a very large prospective database to estimate the frequency of this phenomenon and to look for correlative prognostic factors. METHODS: Patients with histologically or cytologically proven NSCLC, treated with palliative RT to a dose of < or = 36 Gy, were identified from a prospective database containing details of 3035 new patients registered from 1984-1990...

Cisplatin-based (CDDP-based) adjuvant chemotherapy of non-small cell lung cancer (NSCLC) was reported to yield 5-15% improvement in 5-year survival compared to complete resection alone. The importance of information concerning preselection of good responders has become increasingly evident. The purpose of our study is the establishment of a preselection of good responders for CDDP-based adjuvant chemotherapy. We investigated protein expressions comparing intensity between parent strains (H69 and PC14 lung cancer cultured cells) and resistant strains against CDDP using 2-dimensional polyacrylamide gel electrophoresis (2-DE)...

Surgical material (removed lungs or their parts) from 58 patients operated in 1993-1998 was investigated. Lung adenocarcinomas (LAC) are characterized by low proliferative activity of tumor cells. With a decrease of LAC differentiation, tumor cell death by terminal differentiation also diminished which was accompanied by low bcl-2 expression and enhancement of spontaneous apoptosis with active accumulation of protein products of p53 expression in tumor cells nuclei. Expression of c-myc and bax remained unchanged...

Bifunctional 1,2,3-dithiazoles bridged with azine and phenylenediamine spacers have been prepared, with a view to determining the extent of communication between the two dithiazole rings as a function of the electronic and steric demands of the bridge. The crystal structure of the closed-shell diazine derivative [S(2)NClC(2)=NN=C(2)ClNS(2)] is rigorously planar. Cyclic voltammetry on this compound indicates two reversible one-electron oxidations. The radical cation state has been characterized by EPR spectroscopy and by crystal structure determination of its 1:1 PF(6)(-) salt...
