BACKGROUND Beclin 1 plays an essential role in autophagy; however, the regulation of Beclin 1 expression remains largely unexplored. An earlier ChIP-on-chip study suggested Beclin 1 could be an E2F target. Previously, we also reported that 14-3-3tau regulates E2F1 stability, and is required for the expression of several E2F1 target genes. 14-3-3 proteins mediate many cellular signaling processe...
The molecular mechanism of autophagy and its relationship to other lysosomal degradation pathways remain incompletely understood. Here, we identified a previously uncharacterized mammalian-specific protein, Beclin 2, which, like Beclin 1, functions in autophagy and interacts with class III PI3K complex components and Bcl-2. However, Beclin 2, but not Beclin 1, functions in an additional lysosom...
Beclin 1, the mammalian orthologue of yeast Atg6, has a central role in autophagy, which has been linked to diverse biological processes including immunity, development, tumor suppression, lifespan extension, etc. However, the relevant study about Beclin 1 is rare in fish compared with mammals. In this study, we isolated Beclin 1 gene from the kidney tissue of common carp (Cyprinus carpio) usin...
The autophagy-related gene Beclin-1 is critical in the regulation of tumourigenesis and progression, but its role in oral tongue squamous cell carcinoma (OTSCC) has not yet been reported. This study aimed to investigate Beclin‑1 expression and its significance in OTSCC. Beclin‑1 expression was assessed by reverse transcription‑quantitative polymerase chain reaction or western blot analysis in 1...
In the present study, the expression of Beclin 1 in osteoarthritis (OA) cartilage tissue was investigated, and also its role in proliferation, apoptosis and expression of matrix metalloproteinases (MMPs) in chondrocytes obtained from patients with OA. Beclin 1 expression in cartilage tissue from OA patients, and in the age- and sex-matched controls, was detected by immunohistochemistry, semi-qu...
AIM OF THE STUDY We determined the expression of beclin-1 in gallbladder carcinoma, analyzed the association of beclin-1 expression with clinicopathologic parameters and prognosis, and investigated the relationship between microvessel density and beclin-1 expression. MATERIAL AND METHODS Tissue microarray blocks containing 118 primary gallbladder tumor sites were used. Clinical parameters and...
Background The aggregation of tau hyperphosphorylation (p-tau) into neurofibrillary tangles (NFT) is a hallmark in the histopathology Alzheimer’s disease (AD). Our previous experiments found that β-asarone could prevent injury PC12 cells induced by A 1–42 , but it fight cell damage p-tau okadaic acid (OA) poorly understood. Objectives emphasis this study lies β-asarone’s therapeutical effect on...
BACKGROUND Beclin 1 is a main actor of autophagy. The expression of Beclin 1 and its prognostic role in gastric cancer is largely unexplored. The purpose of the present study is to investigate the expression of beclin 1 in gastric cancer cells, tissues and its relationship with prognosis. METHODS The expression of Beclin 1 was detected in 271 specimens of lymph-node positive gastric cancer pa...
BACKGROUND Beclin-1, a key regulator of autophagy. Microtubule-associated protein 1 light chain 3 (LC3), is involved in autophagsome formation during autophagy. The autophagic genes beclin-1 and LC3 paly an important role in the development and progression of tumor. This study was designed to investigate the expression of beclin-1 and LC3 and to clarify their clinical significance in hypopharyn...
Beclin 1 is an autophagy-associated protein involved in apoptosis and drug resistance, as well as various malignancies. We investigated the expression of Beclin 1 protein in ovarian epithelial tissues and correlated it with the prognosis of ovarian cancer. Beclin 1 protein expression was determined using immunohistochemistry in 148 patients with ovarian epithelial cancer, 26 with ovarian border...
