Promising Response with PI3K Inhibitor for a Patient with Heavily Pretreated PIK3CA Mutation Head-and-Neck Cancer by Ming-Jing Lee, Hsiang-Fong Kao

“…Several pathways have been identified in HNSCC, including the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway. The PI3K/AKT/mTOR pathway is frequently dysregulated in various cancers due to activating mutations or amplification of PIK3CA. …”

Impact of 17-alpha ethinyl estradiol (EE2) and diethyl phthalate (DEP) exposure on microRNAs expression and their target genes in differentiated SH-SY5Y cells by Agnese Graziosi, Camilla Corrieri, Giulia Sita, Luca Ghelli, Sabrina Angelini, Roberta d’Emmanuele di Villa Bianca, Emma Mitidieri, Raffaella Sorrentino, Patrizia Hrelia, Fabiana Morroni

“…Gene expression analysis revealed the upregulation of EGFR, IGF1R, BTG2, and SH3BP4, implicating these miRNAs in the regulation of the Ras and PI3K/Akt/mTOR pathways. Our findings highlight distinct cellular responses: DEP disrupts PTEN activity, while EE2 enhances phosphorylation within the PI3K/Akt/mTOR pathway, promoting pro-survival and anti-apoptotic signals. …”

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). …”
