Abstract:

A 66-year-old woman was referred to our hospital due to the abnormal shadow on chest X-ray. Computed tomography(CT) scan revealed a mass in the lower lobe of the right lung and the serum CA19-9 level was 1,600 U/ml. Under the diagnosis of adenocarcinoma by bronchoscopic brushing cytology, right lower lobectomy with mediastinal lymph node dissection was performed. Histopathological examination showed mixed invasive mucinous and non-mucinous adenocarcinoma [World Health Organization (WHO) 8th] of stage IA3 with T1cN0M0[ Union for International Cancer Control( UICC) 8th]. Immunohistochemically, the tumor cells were stained positively for CA19-9. Postoperative course was uneventful and the CA19-9 level decreased to 35.5 U/ml 2 months after operation.

Mucin Agarose Gel Electrophoresis: Western Blotting for High-molecular-weight Glycoproteins

Mucins are high-molecular-weight glycoconjugates, with size ranging from 0.2 to 200 megadalton (MDa). As a result of their size, mucins do not penetrate conventional polyacrylamide gels and require larger pores for separation. We provide a detailed protocol for mucin agarose gel electrophoresis to assess relative quantification and study polymer assembly.

Establishment and Characterization of Three Afatinib-resistant Lung Adenocarcinoma PC-9 Cell Lines Developed with Increasing Doses of Afatinib

A method for establishing afatinib-resistance cell lines from lung adenocarcinoma PC-9 cells was developed, and resistant cells were characterized. The resistant cells can be used to investigate epidermal growth factor receptor tyrosine kinase inhibitor-resistance mechanisms, applicable for patients with non-small cell lung...

A Strategy for the Study of IL-9-Producing Lymphoid Cells in the Nippostrongylus brasiliensis Infection Model

IL-9-expressing T and ILC2 cells are induced during N. brasiliensis infection, yet their characterization has been largely overlooked in the infected intestine due to their low frequency and differential kinetics. This protocol describes the isolation of these cells from different target organs and confirmation of their identity via flow cytometry at different infection...
