Collectively, our study illustrated a Linc00173-mediated process that facilitated chemoresistance and progression in SCLC, which might provide treatment strategy against SCLC.
Immunohistochemical expression of UCHL1 was significantly associated with postoperative survival in patients with HGNEC and contributed towards distinguishing SCLC from LCNEC.
To investigate the role of miR-7-5p in the chemo-resistance of SCLC cells to doxorubicin, mimic or inhibitor of miR-7-5p was transfected into SCLC cells, and the effect of miR-7-5p on homologous recombination (HR) repair was analyzed by HR reporter assays.
KLK8 was downregulated, and the messenger RNA (mRNA) of four other genes (PC, SCUBE1, STC1, and GPM6A) was upregulated mRNA in cells overexpressing miR-22, which was in accordance with the bioinformatics analysis. miR-22 could enhance the radiosensitivity of SCLC by targeting WRNIP1.
The stem cell marker SOX2 was found in all CTC lines and SCLC GLC14/16, whereas elevated expression of Oct-3/4 and Nanog was restricted to BHGc26 and UHGc5.

The median age at time of NEPC was 68.1 years, median prostate-specific antigen (PSA) was 1.20 ng/ml (0.14 ng/mL small-cell carcinoma, 1.55 ng/mL mixed carcinoma) and sites of metastases included bone (72.6%), lymph node (47.0%), and viscera (65.5%).
Using an in vitro cell coculture system, we found that the coculturing of SCLC cells with human brain microvascular endothelial cells (HBMECs) led to an increased expression of S100A16 in SCLC cells.
