Wei Li, Aiqin Nie, Longyu Jin, Yubo Cui, Ning Xie & Gaohua Liang
In the present study, we aimed to investigate the role of long non-coding RNA terminal differentiation-induced non-coding RNA (TINCR) in cisplatin (DDP) resistance of choroidal melanoma (CM) and the potential molecular mechanisms. CM and non-CM tissues were collected from 60 CM patients. DDP-resistant CM cells were obtained by selection with linearly increased DDP treatment. The expression levels of TINCR, microR-19b-3p (miR-19b-3p), and extracellular signal-regulated kinase 2 (ERK-2) were detected by quantitative real-time PCR. Cholecystokinin octapeptide...

Stachydrine is effective and selective against blast phase chronic myeloid leukaemia through inhibition of multiple receptor tyrosine kinases

Ruixin Gu, Wei Zhang & Dandan Xu
Resistance to BCR-ABL tyrosine kinase inhibitor (TKI) is the cause of treatment failure in blast phase chronic myeloid leukaemia (BP-CML). Agents that act synergistically with BCR-ABL TKI are required to improve response. This work investigated the effects of stachydrine in CML. CML cells were treated with control or stachydrine at 20, 40 and 80 µM. Proliferation and apoptosis were examined after 72 h treatment. Combination studies were performed in four groups: control, TKI, stachydrine and...

Identification of HPCAL1 as a specific autophagy receptor involved in ferroptosis

Xin Chen, Xinxin Song, Jingbo Li, Ruoxi Zhang, Chunhua Yu, Zhuan Zhou, Jiao Liu, Siyan Liao, Daniel J. Klionsky, Guido Kroemer, Jinbao Liu, Daolin Tang & Rui Kang
Selective macroautophagy/autophagy maintains cellular homeostasis through the lysosomal degradation of specific cellular proteins or organelles. The pro-survival effect of selective autophagy has been well-characterized, but the mechanism by which it drives cell death is still poorly understood. Here, we use a quantitative proteomic approach to identify HPCAL1 (hippocalcin like 1) as a novel autophagy receptor for the selective degradation of CDH2 (cadherin 2) during ferroptosis. HPCAL1-dependent CDH2 depletion increases susceptibility to ferroptotic death by reducing...

Atg1-mediated Atg11 phosphorylation is required for selective autophagy by regulating its association with receptor proteins

Weijing Yao, Yixing Li, Yingcong Chen, Yuting Chen, Yu Xie, Miaojuan Ye, Ying Zhang, Xiangjun Chen, Xiaoyong Wu, Yuyao Feng, Zhi Hong, Yigang Wang, Wei Liu & Cong Yi
Atg11 is an adaptor protein required for the induction of selective autophagy via receptor binding. However, our understanding of the molecular mechanisms by which it regulates selective autophagy remains incomplete. Here, we show that Atg11 is phosphorylated by Atg1. Rapamycin treatment or starvation conditions induced slower electrophoretic mobility of Atg11 in an Atg1 kinase activity-dependent manner. Through in vitro kinase assays combined with mutagenesis, we determined that Atg1 phosphorylates S949, S1057, and S1064 residues in...
