Yes-associated protein 1 (YAP1) has attracted attention for its potential in the treatment of various types of malignancies. The Hippo-YAP1 axis is inhibited in bladder cancer (BC), which is a major driver of BC progression and oncogenesis. Hippo pathway activity is controlled by the phosphorylation cascade in the MST1/2-LATS1/2-YAP1 axis, in addition to other modifications such as ubiquitination of the Hippo pathway proteins through the co-regulation of E3 ligases and deubiquitinases.

Background: The influences of blood lipids and lipid-regulatory medications on the risk of bladder cancer have long been suspected, and previous findings remain controversial. We aimed to assess the causality between blood lipids or lipid-regulatory medications and bladder cancer susceptibility by means of a comprehensive Mendelian Randomization (MR) study.

Methods: Genetic proxies from genome-wide association studies (GWAS) of four blood lipid traits and lipid-lowering variants in genes encoding the targets of lipid-regulatory medications were employed.

Article Synopsis
  • Scientists are studying why some bladder cancer cells can resist a drug called cisplatin, which is used to treat cancer.
  • They found that a protein named MAT2A helps these resistant cancer cells use a substance called methionine to survive.
  • By targeting MAT2A and another protein called SLC7A6, researchers believe it might be possible to make these resistant cancer cells more vulnerable to cisplatin treatment.

Background: The clinical significance and immune correlation of CD103 cells in prostate cancer (PCa) remain explored.

Methods: In total, 1080 patients with PCa underwent radical prostatectomy from three cohorts were enrolled for retrospective analysis. Tumour microarrays were constructed and fresh tumour samples were analysed by flow cytometry.

Recent studies identified Midkine (MDK) as playing a key role in immune regulation. In this study, we aimed to discover the clinical significance and translational relevance in prostate cancer (PCa). We retrospectively analyzed 759 PCa patients who underwent radical prostatectomy from Huashan Hospital, Fudan University (training cohort, n = 369) and Chinese Prostate Cancer Consortium (validation cohort, n = 390).

Our goal was to explore the bioactive constituents of Longsheyangquan (LSYQ) Decoction and elucidate its mechanisms on the treatment of bladder cancer (BCa). A total of 38 compounds were selected based on their pharmacokinetic properties in three large traditional Chinese medicine (TCM) databases. 654 putative targets of LSYQ Decoction were predicted using a structure-based, reverse-docking algorithm online, of which 343 overlapped with BCa-related protein-coding genes.

Clear cell renal cell carcinoma (ccRCC) is one of the most common urogenital tumors with high mortality. Circular RNA (circRNA), as an emerging endogenous RNA, has been proved to play a crucial role in the clear cell renal cell carcinoma (ccRCC) progression. In this study, we obtained circAFAP1 upregulated in ccRCC by high-sequencing and verified by qRT-PCR in several renal cancer cell lines.

Circular RNAs (circRNAs) play critical roles in different diseases. Exosomes are important intermediates of intercellular communication. While both have been widely reported in cancers, exosome-derived circRNAs are rarely studied.

Circular RNAs (circRNAs) drive several cellular processes including proliferation, survival, and differentiation. Here, we identified a circRNA hsa_circ_0007813, whose expression was upregulated in bladder cancer. High hsa_circ_0007813 expression was associated with larger tumor size, higher primary tumor T stage, and higher pathologic grade.

Bladder cancer (BC) is known as a common and lethal urinary malignancy worldwide. Circular RNAs (circRNAs), an emerging non-coding RNA, participate in carcinogenesis process of several cancers including BC. In this study, high-throughput sequencing and RT-qPCR were applied to discover and validate abnormal high expression of circUBE2K in BC tissues.

Bladder cancer is a severe cancer with high mortality because of invasion and metastasis. Growing evidence has revealed that circular RNAs play critical roles in biological function, which is closely connected to proliferation and invasion of bladder cancer. In our study, we employed qRT-PCR, RNA fluorescence hybridization (FISH), 5-ethynyl-2'-deoxyuridine (EdU), CCK-8, Transwell assays, luciferase reporter assays, xenografts, and live imaging to detect the roles of circular RNA binding protein with multiple splicing (circRBPMS) in bladder cancer (BC).

Background: Bladder carcinoma (BC) is one of the most prevalent and malignant tumors. Multiple gene signatures based on BC metabolism, especially regarding glycolysis, remain unclear. Thus, we developed a glycolysis-related gene signature to be used for BC prognosis prediction.

Double-lumen endotracheal tube (DLET) and one-lung ventilation (OLV) have been generally accepted as the classic anesthetic method in video-assisted thoracoscopic total thymectomy (VATT). However, there are still some disadvantages of DLET. Two-lung ventilation (TLV) with single-lumen endotracheal tube (SLET) is considered to be an alternative in VATT to avoid these disadvantages.

Background: Uniport video-assisted thoracoscopic surgery (VATS) has emerged as a less invasive approach for the treatment of non-small cell lung cancer (NSCLC). However, whether uniport VATS has more potential advantages over multiport VATS remains controversial. This meta-analysis aimed to compare the perioperative efficacy of uniport and multiport VATS for T1-3N0M0 NSCLC.

Background: Stereotactic body radiotherapy (SBRT) or stereotactic ablative radiotherapy (SABR) has been reported to be a comparable alternative therapy to surgery for patients with T1-3N0M0 non-small cell lung cancer (NSCLC). However, it has not been clarified whether SBRT/SABR is as effective as surgery. We conducted this study to compare the efficacy of SBRT/SABR and surgery in the treatment of T1-3N0M0 NSCLC.

Purpose: Video-assisted thoracoscopic surgery (VATS) is widely used in thoracic surgery and increasingly applied to pulmonary metastasectomy. The purpose of this study was to identify prognostic factors of patients undergoing VATS pulmonary metastasectomy from colorectal cancer (CRC).

Methods: Between January 2005 and June 2015, a total of 154 patients underwent VATS pulmonary metastasectomy from CRC.
