Clinical value of exhaled breath condensate let-7 in non-small cell lung cancer.

Clinical value of exhaled breath condensate let-7 in non-small cell lung cancer. Int J Clin Exp Pathol. 2020;13(2):163-171 Authors: Chen JL, Han HN, Lv XD, Ma H, Wu JN, Chen JR Abstract Non-small cell lung cancer (NSCLC) is one of the most common causes of tumor-associated mortality worldwide. Early diagnosis is the key focus for improving prognosis. In the present study, the association between exhaled breath condensate (EBC) let-7 and NSCLC diagnosis and clinicopathologic characteristics was investigated in order to explore non-invasive simple technological therapeutic methods. The expression levels of let-7 from 180 samples were analyzed using the reverse transcription-quantitative polymerase chain reaction (RT-qPCR), consisting of 30 patients with NSCLC (lung cancer and para-carcinoma tissues, serum and EBC) and 30 healthy volunteers (serum and EBC). The results revealed that the let-7 levels in tumor tissues, serum, and EBC in NSCLC were significantly decreased compared with the control group (all, P

microRNA-23B inhibits non-small cell lung cancer proliferation, invasion and migration via downregulation of RUNX2 and inhibition of Wnt/Β-catenin signaling pathway. J Biol Regul Homeost Agents. 2020 Jun 04;34(3): Authors: Wang HX, Wang XY, Fei JW, Li FH, Han J, Qin X Abstract Non-small cell lung cancer (NSCLC) accounts for about 85% of all lung cancer cases. MicroRNAs (miRNAs/miRs) have been reported to play significant roles in the progression of human tumors, however, the expression and biological role of miR-23b in NSCLC remains elusive. Underexpression of miR-23b was detected in NSCLC tissues...

CONCLUSIONS: In our study, GBP1 was firstly identified as a novel oncogene in NSCLC. Furthermore, it could promote NSCLC development and paclitaxel resistance by inducing Wnt/β-catenin signaling pathway. PMID: 32495881 [PubMed - in process]

Rationale: Pulmonary sarcomatoid carcinoma (PSC) is an uncommon type of non-small cell lung cancer, exhibiting aggressive behavior and resistance to the conventional chemoradiotherapy. To date, the optimal treatment for PSC has not been elucidated. Patient concerns: Three male patients including a 69-year-old smoker (Case 1), a 45-year-old non-smoker (Case 2), and a 69-year-old smoker (Case 3) were admitted because of cough, back pain, and loss of body weight respectively. Diagnoses: Radiographical examinations in these patients showed bulky intrathoracic lesions, which were pathologically diagnosed as PSC staging ...

A new pattern of response, so-called hyperprogressive disease (HPD), is emerging during treatment with immune checkpoint inhibitors (ICIs). Our aim was to investigate the prevalence of such a phenomenon and to assess its association with clinical variables and metabolic parameters by 18F-FDG PET/CT. Methods: Data from 50 patients (34 men and 16 women; median age, 73 y) with non–small cell lung carcinoma treated with ICIs were prospectively collected. All patients underwent contrast-enhanced CT, 18F-FDG PET/CT, and complete peripheral blood sampling at baseline before ICI treatment. HPD was defined according to clinic...

Abstract Accumulating evidence suggests that ubiquitin-like with plant homeodomain and ring finger domains 1 (UHRF1) is overexpressed in non-small cell lung cancer (NSCLC); however, the expression and function of UHRF1 in the subtype of NSCLC are still unclear. Here, we investigate the expression and prognosis traits of UHRF1 in large NSCLC cohorts and explore the molecular characters during UHRF1 up-regulation. We find that UHRF1 is predominantly overexpressed in lung squamous cell carcinoma (SCC). Surprisingly, the up-regulated UHRF1 is only associated with the overall survival of lung adenocarcinoma (ADC) and k...

Abstract One new naphthalenone, didymelol A (1), and three new naphthols, didymelol B-D (5-7), together with three known naphthalenones, (3S,4R)-3,4,6,8-tetrahydroxy-3,4-dihydronaphthalen-1(2H)-one (2), (S)-4,6,8-trihydroxy-3,4-dihydronaphthalen-1(2H)-one (3), (S)-4,8-dihydroxy-3,4-dihydronaphthalen-1(2H)-one (4), were isolated from the Saussurea laniceps endophytic fungus Didymella glomerate X223. The structures of the isolates were elucidated based on extensive spectroscopic data analysis. The absolute configuration of didymelol A (1) was established through single-crystal X-ray diffraction data and didymelols B...
