The Role of Autophagy in Copper-Induced Apoptosis and Developmental Neurotoxicity in SH-SY5Y Cells by Lu Lu, Ying Zhang, Wei Shi, Qian Zhou, Zhuoqi Lai, Yuepu Pu, Lihong Yin

“…Exposure to Cu²⁺ increased autophagosome accumulation and autophagic flux blockage in terms of increased sequestosome 1 (p62/SQSTM1) and microtubule-associated protein 1 light chain 3B (LC3B) II/LC3BI expressions and inhibition of the phosphatidylinositol 3-kinase (PI3K)/Akt/mTOR pathway. Furthermore, copper induced apoptosis, characterized by increased expressions of Bcl2 X protein (Bax), caspase 3, and Poly (ADP-ribose) polymerase (PARP) and decreased expression of B-cell lymphoma 2 (Bcl2). …”

Accumulation of advanced oxidation protein products aggravates bone-fat imbalance during skeletal aging by Yu-Sheng Huang, Jia-Wen Gao, Rui-Feng Ao, Xin-Yu Liu, Di-Zheng Wu, Jun-Long Huang, Chen Tu, Jing-Shen Zhuang, Si-Yuan Zhu, Zhao-Ming Zhong

“…The antioxidant NAC, after scavenging ROS, ameliorated the AOPPs-induced lineage switch and senescence in MSCs by inhibiting the PI3K/AKT/mTOR pathway. Conclusion: Our findings revealed the involvement of AOPPs in age‐related switch between osteogenic and adipogenic differentiation, and illuminated a novel potential mechanism underlying bone-fat imbalance during skeletal aging. …”

A General Framework for Closed Loop Negative Feedback Multivariable Physiological Control Systems: Existence, Uniqueness, and Stability of Homeostatic Equilibrium Points by Anna Procopio, Annarita Tedesco, Fabrizio Lo Regio, Giuseppe Cesarelli, Leandro Donisi, Carlo Ricciardi, Alessio Merola, Alfonso Maria Ponsiglione, Maria Romano, Francesco Montefusco, Carlo Cosentino, Francesco Amato

“…To this regard, in this paper, the existence, possible uniqueness and stability properties of the homeostatic equilibrium points of the general model are investigated; the theoretical framework is then illustrated through two real-world case-studies: (i) the PI3K/AKT/mTOR pathway nonlinear dynamics, a critical regulator of cellular growth, proliferation, and survival; (ii) the control mechanism of the neuromuscular stretch reflex, among the prime triggers implicated in postural control. …”

Hybridization-based discovery of novel quinazoline-2-indolinone derivatives as potent and selective PI3Kα inhibitors by Changqun Liu, Yuening Cao, Yi Zuo, Chaozheng Zhang, Senmiao Ren, Xin Zhang, Chuanqi Wang, Yingjie Zeng, Jie Ling, Yilan Liu, Zixian Chen, Xiujun Cao, Zhengzhi Wu, Chuantao Zhang, Jun Lu

“…Moreover, compound 8 effectively suppressed the viability of B16, HCT116, MCF-7, H22, PC-3, and A549 cells (IC50 values: 0.2 μM ∼ 0.98 μM), and dramatically inhibited the proliferation and migration of NSCLC cells, as well as induced mitochondrial apoptosis through the PI3K/Akt/mTOR pathway. Importantly, compound 8 demonstrated potent in vivo anti-tumor activity in non-small cell lung cancer mouse models without visible toxicity. …”

<i>Cichorium intybus</i> L. Oligo-Polysaccharides (CIO) Exerts Antianxiety and Antidepressant Effects on Mice Experiencing Behavioral Despair and Chronic Unpredicted Mild Stress by Yanqin Luo, Xueyi Bei, Yiwen Zhang, Xinran Sun, Yongzhi Zhao, Fang Chen, Ruile Pan, Qi Chang, Qinghu He, Xinmin Liu, Ning Jiang

“…This study explores the antianxiety and antidepressant effects and mechanisms of CIOs by using acute behavioral despair and chronic unpredictable mild stress mice models and measuring the levels of 5-HT and the expression of proteins related to the BDNF/ERK and PI3K/Akt/mTOR pathways. Moreover, 56 male C57BL/6N mice were used to test behavioral despair. …”
