Abstract

Accumulating evidence demonstrated the pivotal roles of circular RNAs (circRNAs) in several types of cancers. However, the study relevant to the biological functions of circRNAs in osteosarcoma (OS) is still very limited. Recently, hsa_circ_0007534 has been proved to play key roles in colorectal carcinoma and glioma. In this study, qRT-PCR was used to determine hsa_circ_0007534 expression in OS tissues and cells. The clinical value of hsa_circ_0007534 was further explored. Additionally, cell growth, clone formation ability and cell apoptosis were assessed after hsa_circ_0007534 silenced. The xenograft study was further induced to investigate the roles of hsa_circ_0007534 in vivo. Moreover, AKT/GSK-3β pathway was measured to illustrate the mechanism of hsa_circ_0007534 exerts in OS progression. The data demonstrated that hsa_circ_0007534 is overexpressed in OS tissue samples and cells and this up-regulation is related with larger tumor size and poorer differentiation degree. Moreover, hsa_circ_0007534 is a dismal prognostic biomarker for OS patients. For the functional assays, knockdown of hsa_circ_0007534 suppresses OS cell growth in vitro and in vivo. In addition, hsa_circ_0007534 protects against cell apoptosis via Bcl-2/casp...Continue Reading

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Apoptotic Caspases

Apoptotic caspases belong to the protease enzyme family and are known to play an essential role in inflammation and programmed cell death. Here is the latest research.
