Circular RNAs (circRNAs) play important roles in tumorigenesis, including lung cancer. However, the expression profile and clinical value of circRNAs in lung adenocarcinoma remain unclear. The purpose of this study was to establish the circRNAs expression profile of lung adenocarcinoma and determine its potential diagnostic and prognostic value.
The global expression profile of circRNAs in lung adenocarcinoma tissue was determined from five paired lung adenocarcinoma tissues and adjacent normal tissues. The expression levels of selected candidate circRNA were validated by qRT-PCR. Sequence analysis was used to confirm the specificity of amplified circRNA. The candidate circRNA level was further detected in plasma samples from lung adenocarcinoma patients and healthy controls. The relationships between their levels and clinicopathological factors were explored. Receiver operating characteristic (ROC) curve was constructed to differentiate lung adenocarcinoma from healthy controls. Kaplan-Meier was performed _0001715 level was an independent prognostic factor for the OS.
Our study revealed an aberrant circRNA expression profile in lung adenocarcinoma, and hsa_circ_0001715 is up-regulated and could act as a novel diagnostic and prognostic biomarker for lung adenocarcinoma.

Renal cell carcinoma (RCC) is the most common type of kidney cancer in adults. Exosomes are membrane-enclosed extracellular vesicles, and exosomal RNA can be a biomarker for cancer diagnosis and prognosis in RCC patients. We aim to identify differences in miRNA expression profiles in peripheral blood exosomes between RCC patients and healthy subjects as well as to investigate novel markers of RCC.
We performed exosomal miRNA sequencing of plasma samples obtained from five RCC patients and five control subjects, subsequently 22 RCC patients and 16 control subjects were investigated using qPCR to confirm the differential miRNA which from plasma exosomal RNA sequencing. ROC curves were constructed to assess the diagnostic accuracy of exosomal miRNAs as diagnostic biomarkers of RCC.
Exosomes were isolated with the exoeasy maxi kit and confirmed using TEM and NTA. They have a spherical structure with a diameter of approximately 40-180 nm. The exosomal miRNA sequence results showed that a total of 2357 miRNAstudy revealed that the expression levels of hsa-mir-92a-1-5p, hsa-mir-149-3p and hsa-mir-424-3p were significantly abnormal in RCC patients, which may be novel biomarkers for RCC diagnosis.[This corrects the article DOI 10.2147/OTT.S263815.].
Cancer cells with stemness and epithelial-to-mesenchymal transition (EMT) features display enhanced malignant and metastatic potential. This study aimed to introduce a new methodology developed in order to investigate the co-expression of a stemness (OCT4) and EMT markers on single circulating tumor cells (CTCs) of patients with localized urinary bladder cancer and their potential prognostic prediction value.
Between April 2015 and July 2015, blood samples of 51 consecutive patients diagnosed with high risk bladder cancer (cT
N
M
) were prospectively investigated for CTCs. Peripheral blood (5 mL) was drawn before primary transurethral resection. Detection of CTCs was performed using the CanPatrol
system. Nucleic acid probes were used to identify CTCs, and expression levels of epithelial and mesenchymal genes in CTCs were examined by situ hybridization assay.
All patients received radical cystectomy with pelvic lymph nodes dissection. CTCs were detected in 44 of 51 (86.3%) patients, respectively. Thd a CTCs expressing high OCT4, along with Mes were more frequently detected in patients with MIBC, suggesting that these cells may prevail during tumor muscle invasion and disease progression.
Non-small-cell lung cancer (NSCLC) is the leading cause of cancer-related mortality worldwide. However, the molecular mechanism of NSCLC remains unknown. Accumulating data show that Rhotekin 2 (RTKN2) functions as a novel crucial regulator of diverse biological processes; however, its pathological role in NSCLC remains unclear.
In this study, we investigated the function of RTKN2 in NSCLC. LArginine The expression of RTKN2 mRNA was analyzed in tumor tissues and paired adjacent tissues from patients by qRT-PCR. The role of RTKN2 in cell proliferation, apoptosis, migration, and invasion was investigated. The potential mechanisms were explored.
We found that the level of RTKN2 mRNA was up-regulated in NSCLC tissues and cell lines. RTKN2 knockout inhibited the proliferation of human NSCLC cell lines A549 via inducing apoptosis by increasing the level of Bax and decreasing the level of Bcl-2. Furthermore, silencing of RTKN2 reduced the migration and invasion of A549 cells through up-regulated matrix metalloproteinase-9 (MMP9) and MMP2 expression.
These data suggest that RTKN2 may not only be a prognostic biomarker candidate but also provide a potential therapeutic target for NSCLC diagnosis and treatment.

The study aims to investigate and compare the efficacy and safety of intraoperative
I implantation and postoperative irradiation after surgical decompression and stabilization in the treatment of patients with metastatic epidural spinal cord compression (MESCC).
The study retrospectively enrolled 122 MESCC patients treated with surgical decompression and pedicle stabilization combined with
I brachytherapy (the brachytherapy group) or postoperative radiotherapy (the irradiation group). Operation time, intraoperative blood loss, pain relief, postoperative ambulatory status, postoperative survival outcome, complications, and length of hospitalization were collected and compared between the two groups. Ten potential risk factors were analyzed for postoperative survival outcome.
No significant difference was found in baseline characteristics between the two groups (P>0.05). Postoperative VAS score was significantly decreased, as compared with preoperative scores in both groups (P˂0.001). The VAS in the brachytherapy group was significantly lower than that in the irradiation group at postoperative 1 month, 3 months, and 6 months (P˂0.
