Rosin Derivative IDOAMP Inhibits Prostate Cancer Growth via Activating RIPK1/RIPK3/MLKL Signaling Pathway.

Rosin derivatives such as dehydroabietic acid and dehydroabietic amine belonging to diterpenoids have similar structure with androgen that inhibited the occurrence and development of prostate cancer. In this study, the effects and possible mechanism of the rosin derivative IDOAMP on prostate cancer were investigated. Our results showed that IDOAMP effectively inhibited cell viabilities of LNCaP, PC3, and DU145 prostate cells.

Moderate activation of autophagy regulates the intracellular calcium ion concentration and mitochondrial membrane potential in beta-amyloid-treated PC12 cells.

Alzheimer's disease (AD) is an age-related and progressive neurodegenerative disease. Aggregated beta-amyloid (Aβ) disturbs Ca(2+) homeostasis and causes mitochondrial dysfunction and finally underlies AD. Recent evidence suggests that autophagy initiation by Beclin-1 protein might be involved in the pathogenesis of AD.

Beta-asarone attenuates amyloid beta-induced autophagy via Akt/mTOR pathway in PC12 cells.

Alzheimer's disease (AD) is an age related and progressive neurodegenerative disease. Autophagy is a self-degradative process and plays a critical role in removing long-lived proteins and damaged organelles. Recent evidence suggests that autophagy might be involved in the pathogenesis of AD.

Dynamic of neurochemical alterations in striatum, hippocampus and cortex after the 6-OHDA mesostriatal lesion.

Immediate neurochemical alterations produced by 6-OHDA could explain the general toxic pattern in the central nervous system. However, no evidences describe the effects of 6-OHDA on early changes of neurotransmitters in rats' striatum, cortex and hippocampus. In our study, unilateral 6-OHDA injection into medial forebrain bundle (MFB) was used in rats, then five neurotransmitters were analyzed at 3, 6, 12, 24, 48 and 72 h, respectively.

Dynamic expressions of Beclin 1 and tyrosine hydroxylase in different areas of 6-hydroxydopamine-induced Parkinsonian rats.

Beclin 1, a regulator of the autophagy pathway, plays an important role in Parkinson's disease (PD). However, the crucial mechanism of Beclin 1 in PD remains unclear. Therefore, we investigated dynamic expressions of Beclin 1 and tyrosine hydroxylase (TH) in different brain areas of 6-OHDA-induced rats.

Establish a flow cytometric method for quantitative detection of Beclin-1 expression.

Flow cytometry is an advanced technology for efficient, rapid, specific and multi-parameter analysis of single cells in various basic research fields including cytobiology, immunology, genetic, hematology and other basic research. Beclin-1 protein is an important indicator in monitoring autophagic activity. However, quantitative flow cytometry had been rarely reported till now to be applied in the detection of Beclin-1 expression.

Increased expression of Beclin-1-dependent autophagy protects against beta-amyloid-induced cell injury in PC12 cells [corrected].

Alzheimer's disease (AD) is an age-related and progressive neurodegenerative disease. Beta-amyloid (Aβ) plays an important role in the pathogenesis of AD. Autophagy is a self-degradative process and its related protein Beclin-1 is involved in the initiation of autophagy.

Beta-asarone attenuates ischemia-reperfusion-induced autophagy in rat brains via modulating JNK, p-JNK, Bcl-2 and Beclin 1.

Beta-asarone has significant pharmacological effects on the central nervous system. It can attenuate neuronal apoptosis, but its effects on the brain ischemia-reperfusion-induced autophagy have not been reported yet. Our study was a two-stage procedure: evaluation of β-asarone effects on the autophagy at first, and then analysis of the possible mechanism.
