Open AccessGli1 inhibition suppressed cell growth and cell cycle progression and induced apoptosis as well as autophagy depending on ERK1/2 activity in human chondrosarcoma cells
The transcription factor glioma-associated oncogene 1 (Gli1) has been recognized as a very important nuclear executor at the distal end of the Hedgehog (Hh) signal pathway, which has crucial roles in regulatin...

Open AccessTetrandrine blocks autophagic flux and induces apoptosis via energetic impairment in cancer cells
Lysosomes are acidic organelles that have a crucial role in degrading intracellular macromolecules and organelles during the final stage of autophagy. Tetrandrine (Tet), a bisbenzylisoquinoline alkaloid, was r...

Open AccessMicroRNA-34a: a potential therapeutic target in human cancer
MicroRNAs (miRs) are small noncoding RNAs that negatively regulate gene expression by binding to the three untranslated regions of their target mRNAs. Deregulations of miRs were shown to play pivotal roles in ...

Open AccessMir-509-5p joins the Mdm2/p53 feedback loop and regulates cancer cell growth
Although the Mdm2/p53 interaction has been well documented, it is not clear whether there are new microRNAs participating in this regulatory network. Here, we provide evidence that miR-509-5p, which is downreg...

Article
Open AccessPeroxisome proliferator-activated receptor α activation attenuates the inflammatory response to protect the liver from acute failure by promoting the autophagy pathway
Peroxisome proliferator-activated receptor α (PPARα) has been reported to induce a potent anti-inflammatory response. Autophagy is a recently recognized rudimentary cellular response to inflammation and injury. T...

Article
Open AccessPhosphorylation-dependent mitochondrial translocation of MAP4 is an early step in hypoxia-induced apoptosis in cardiomyocytes
Hypoxic or ischemic apoptosis is often tightly associated with the opening of mitochondrial permeability transition pore (mPTP); however, the molecular mechanisms regulating mPTP and thus mitochondrial-depende...

Open AccessActivation-induced necroptosis contributes to B-cell lymphopenia in active systemic lupus erythematosus
B-cell abnormality including excessive activation and lymphopenia is a central feature of systemic lupus erythematosus (SLE). Although activation threshold, auto-reaction and death of B cells can be affected b...

Open AccessMicroRNA-207 enhances radiation-induced apoptosis by directly targeting akt3 in cochlea hair cells
MicroRNAs (miRNAs) have important roles in various types of cellular biological processes. Our study aimed to determine whether miRNAs function in the regulation of ionizing radiation (IR)-induced cell death i...

Article
Open AccessBMPR2 inhibition induced apoptosis and autophagy via destabilization of XIAP in human chondrosarcoma cells
Bone morphogenetic proteins (BMPs) are multifunctional proteins, and their receptors (BMPRs) have crucial roles in the process of signaling. However, their function in cancer is somewhat inconsistent. It has b...

Open AccessMiR-34c suppresses tumor growth and metastasis in nasopharyngeal carcinoma by targeting MET
Our previous microarray analysis indicated that miR-34c was downregulated in nasopharyngeal carcinoma (NPC). However, little is known about the function and molecular mechanism of miR-34c in NPC. In this study...
