SOX9 has distinct roles in the formation and progression of different non-small cell lung cancer histotypes.

The transcription factor SOX9 is a key regulator of multiple developmental processes and is frequently re-expressed in non-small cell lung cancer (NSCLC). Its precise role in the progression of NSCLC histotypes has, however, remained elusive. We show that SOX9 expression relates to poor overall survival and invasive histopathology in human non-mucinous adenocarcinoma and is absent in murine early minimally invasive and low in human in situ adenocarcinoma.

Performance of Finnish biobanks in nationwide pulmonary carcinoid tumour research.

Finnish hospital-integrated biobanks administer millions of formalin-fixed paraffin-embedded tissue samples collected within the clinical diagnostics. According to the Finnish Biobank Act, these samples can be coupled with patients' clinical follow-up data and the data retrieved from national health registries. We collected a nationwide pulmonary carcinoid tumour series from Finnish biobanks to study prognostic factors as well as to explore how the number of tumours found in the Finnish biobanks corresponds to the number of tumours registered by the Finnish Cancer Registry (FCR).

Receptor Tyrosine Kinase Signaling Networks Define Sensitivity to ERBB Inhibition and Stratify -Mutant Lung Cancers.

Most non-small cell lung cancers (NSCLC) contain nontargetable mutations, including , or alterations. By coupling drug sensitivity profiling with drug response studies, we aimed to identify drug vulnerabilities for these NSCLC subtypes. Primary adenosquamous carcinoma (ASC) or adenocarcinoma (AC) cultures were established from (KL) tumors or AC cultures from (KP) tumors.

PD-1 and PD-L1 expression in pulmonary carcinoid tumors and their association to tumor spread.

Pulmonary carcinoid (PC) tumors are rare tumors that account for approximately 1% of all lung cancers. The primary treatment option is surgery, while there is no standard treatment for metastatic disease. As the number of PCs diagnosed yearly is increasing, there is a need to establish novel therapeutic options.

CDKN2A copy number and p16 expression in malignant pleural mesothelioma in relation to asbestos exposure.

Background: Deletion of the CDKN2A locus is centrally involved in the development of several malignancies. In malignant pleural mesothelioma (MPM), it is one of the most frequently reported genomic alteration. MPM is strongly associated with a patients' asbestos exposure.
