Aptamers are short RNA or DNA oligonucleotides which can bind with different targets. Typically, they are selected from a large number of random DNA sequence libraries. The main strategy to obtain aptamers is systematic evolution of ligands by exponential enrichment (SELEX). Low efficiency is one of the limitations for conventional PCR amplification of(More)
A proliferation-inducing ligand (APRIL) is highly expressed in colorectal cancer (CRC) tissues and cell lines. However, the biological functions and precise signals elicited by APRIL in CRC have not been fully understood. Here, we used small interfering RNA to selectively deplete APRIL and to determine its tumorigenic effects in a CRC cell line SW480 both(More)
A proliferation-inducing ligand (APRIL) is overexpressed in most tumor cells and tissues, especially in tumors of the alimentary system, such as colorectal cancer (CRC), gastric cancer, and liver cancer. RNA interference (RNAi) has been proved to be a powerful tool for gene knockdown and holds great promise for the treatment of cancer. In this study, the(More)
The traditional collaborative filtering algorithm is a successful recommendation technology. The core idea of this algorithm is to calculate user or item similarity based on user ratings and then to predict ratings and recommend items based on similar users’ or similar items’ ratings. However, real applications face a problem of data sparsity because most(More)
It is well documented that a proliferation-inducing ligand (APRIL), a newly found member of tumor necrosis factor superfamily, overexpressed in the majority of malignancies, plays a potential role in the occurrence and development of these tumors. Herein, we demonstrated that APRIL depletion by using RNA interference in human colorectal cancer (CRC) COLO(More)
A proliferation-inducing ligand (APRIL) is a key cell proliferation-regulatory molecule and have been investigated well enough in immunity regulation and a few of immune diseases. APRIL can stimulate tumor cell growth and is up-expressed in cancer tissues, especially in CRC (colorectal cancer). However, whether inhibition of APRIL can regulate(More)
