Treatment and surveillance for non-muscle-invasive bladder cancer: a clinical practice guideline (2021 edition).

Non-muscle invasive bladder cancer (NMIBC) is a major type of bladder cancer with a high incidence worldwide, resulting in a great disease burden. Treatment and surveillance are the most important part of NIMBC management. In 2018, we issued "Treatment and surveillance for non-muscle-invasive bladder cancer in China: an evidence-based clinical practice guideline".

Actein inhibits glioma growth via a mitochondria-mediated pathway.

Previous studies indicate that the triterpene glycoside Actein from the herb black cohosh inhibits growth of human breast cancer cells. This study sought to investigate the effects of Actein on glioma cell growth and explore the potential mechanisms. Our results showed that administration of Actein significantly inhibited glioma cell viability in a dose- and time-dependent manner.

YAP is closely correlated with castration-resistant prostate cancer, and downregulation of YAP reduces proliferation and induces apoptosis of PC-3 cells.

Yes-associated protein 65 (YAP65) has been implicated as an oncogene, and its expression is increased in human cancer. Previous studies have demonstrated that alterations in YAP activity may result in tumourigenesis of the prostate. With androgen deprivation therapies becoming progressively ineffective, often leading to life‑threatening androgen‑resistant prostate cancer (CRPC).

Methylation‑associated inactivation of LATS1 and its effect on demethylation or overexpression on YAP and cell biological function in human renal cell carcinoma.

Large tumor suppressor 1 (LATS1) gene is one of the key factors in Hippo signaling pathway. Inactivation of LATS1 by promoter methylation was found in colorectal cancer (CRC), head and neck squamous cell carcinoma (HNSCC), astrocytoma, breast cancer and it was proved to be a tumor suppressor. However, its role is unclear in renal cell carcinoma (RCC).

YAP is overexpressed in clear cell renal cell carcinoma and its knockdown reduces cell proliferation and induces cell cycle arrest and apoptosis.

Yes-associated protein (YAP) has been reported to be an oncogene in a number of malignancies. It constitutes an important regulatory mechanism for the Hippo pathway, a key regulator of cell growth and apoptosis. The present study aimed to investigate the clinical significance and the role of YAP in the development of clear cell renal cell carcinoma (ccRCC).

Discordance and clinical significance of ER, PR, and HER2 status between primary breast cancer and synchronous axillary lymph node metastasis.

Discordance of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) status between primary breast cancer, metastatic lesion and synchronous axillary lymph node metastasis has been reported in the series studies. Systemic treatment of primary invasive breast cancer patients with synchronous axillary metastasis is currently based on the biomarker characteristics of the primary tumor; however, hormone receptors and HER2 status may change throughout tumor progression from the primary tumor to the synchronous axillary metastasis. As local metastasis, the synchronous axillary lymph node metastasis may represent the potentially metastatic breast cancer cells much better than the primary tumor.

A detector of an invisible carpet cloaking structure.

Based on transformation optics, we propose a device to detect the presence of a carpet cloaking structure at near field. By using complementary media, the detective device can optically cancel a certain volume of reflective metal and reveal the hidden medium inside the metal. The detective performance of this device is confirmed by full-wave finite-element simulations.

Isolation and enrichment of PC-3 prostate cancer stem-like cells using MACS and serum-free medium.

Prostate cancer stem-like cells (PCSLCs) are considered to be the 'seed' of prostate cancer. The aim of this study was to confirm that the PC-3 cells, which we isolated and enriched from PC-3 cells through magnetic bead cell sorting (MACS) and serum-free medium (SFM) culture, were PCSLCs. Combinations of MACS, flow cytometry (FCM), SFM and immunocytochemistry (ICC) were used to ensure the positive expression of CD133 and CD44 on PC-3 and sphere-forming cell membranes.

Integrin-linked kinase functions as a tumor promoter in bladder transitional cell carcinoma.

The aim of this study was to elucidate the role of the integrin-linked kinase (ILK) gene in development of human bladder transitional cell carcinoma (BTCC). Expression of ILK protein and ILK mRNA in 56 cases of human BTCC tissue and in 30 cases of adjacent normal bladder tissue was detected by immunohistochemistry S-P and reverse transcription polymerase chain reaction (RT-PCR), respectively. Four specific miRNA RNAi vectors targeting human ILK were synthesized and transfected into BIU-87 cells by liposome to obtain stable expression cell strains.

Watching outside while under a carpet cloak of invisibility.

We demonstrate in this work a unique approach for watching outside while hiding in a carpet cloaking based on transformation optics. Unlike conventional carpet cloaking, which screens all the incident electromagnetic waves, we break the cloak and allow incident light get into the carpet. Hence outside information is detected inside the cloak.
