Xiaodan Wang, Xiaolong Wu, Zhenshuo Zhu, Hao Li, Tongtong Li, Qun Li, Peng Zhang, Leijie Li, Dongxue Che, Xia Xiao, Tong Liu, Jinlian Hua & Mingzhi Liao
Spermatogenesis is an important physiological process associated with male infertility. As a kind of post-transcriptional regulation, RNA editings (REs) change the genetic information at the mRNA level. But whether there are REs and what’s the role of REs during the process are still unclear. In this study, we integrated published RNA-Seq datasets and established a landscape of RNA REs during the development of mouse spermatogenesis. Totally, 7530 editing sites occurred in 2012 genes among all...

Myotubularin related protein 7 is essential for the spermatogonial stem cell homeostasis via PI3K/AKT signaling

Dan Zhao, Cong Shen, Tingting Gao, Hong Li, Yueshuai Guo, Feng Li, Chenchen Liu, Yuanyuan Liu, Xia Chen, Xi Zhang, Yangyang Wu, Yi Yu, Meng Lin, Yan Yuan, Xiaofang Chen, Xiaoyan Huang, Shenmin Yang, Jun Yu, Jun Zhang & Bo Zheng
Myotubularin related protein 7 (MTMR7), a key member of the MTMR family, depicts phosphatase activity and is involved in myogenesis and tumor growth. We have previously identified MTMR7 in the proteomic profile of mouse spermatogonial stem cell (SSC) maturation and differentiation, implying that MTMR7 is associated with neonatal testicular development. In this study, to further explore the distribution and function of MTMR7 in mouse testis, we studied the effect of Mtmr7 knockdown on neonatal testicular...

Salicin prevents TNF-α-induced cellular senescence in human umbilical vein endothelial cells (HUVECs)

Fei Guo, Rong Wu & Jian Xu
Cellular senescence is strongly tied to vascular disease. The current study aims to examine ways that endothelial cellular senescence can be prevented and the mechanisms by which prevention of senescence occurs. Human umbilical vein endothelial cells were exposed to TNF-α to induce senescence; then salicin was administered in two doses – 50 and 100 µM – to establish a dose-dependent effect of salicin on SA-β-Gal, G1 cell cycle arrest, expression of p21 and PAI-1, p53...

The role of DRP1 in ropivacaine-induced mitochondrial dysfunction and neurotoxicity

Yan Chen, Lili Yan, Yan Zhang & Xianhui Yang
Ropivacaine is a commonly used local anaesthetic, but its side effects remain largely unknown. In the present study, we investigated the side effects of ropivacaine in human neuronal SH-5Y5Y cells. We show that 0.5% and 1% ropivacaine could cause fission-like mitochondrial morphological changes. Ropivacaine exclusively induces mitochondrial fission protein DRP1, generation of ROS and causes mitochondrial dysfunction including decreasing mitochondrial membrane potential, the activity of cytochrome C oxidase and ATP production. The side effects of...

Cross-linked nanoparticles of silk fibroin with proanthocyanidins as a promising vehicle of indocyanine green for photo-thermal therapy of glioma

De-Li ZhuGe, Li-Fen Wang, Rui Chen, Xin-Ze Li, Zhi-Wei Huang, Qing Yao, Bin Chen, Ying-Zheng Zhao, He-Lin Xu & Jian-Dong Yuan
Instability of silk fibroin nanoparticles (SFNPs) in physiologic condition hinders its application as drug delivery vehicle. Herein, indocyanine green (ICG) loaded silk fibroin nanoparticles (ICG-SFNPs) was firstly prepared and then crosslinked by proanthocyanidins to obtain the stable ICG-CSFNPs for killing the residual tumour niche under near infra-red irradiation (NIR) after surgery. The particle size and zeta potentials of ICG-CSFNPs was 120.1 nm and -40.4 mV, respectively. Moreover, ICG-CSFNPs exhibited good stability of particle size in...

In vitro and in vivo evaluation of didymin cyclodextrin inclusion complexes: characterization and chemosensitization activity

Qing Yao, Meng-Ting Lin, Qing-Hua Lan, Zhi-Wei Huang, Ya-Wen Zheng, Xue Jiang, Yin-Di Zhu, Longfa Kou, He-Lin Xu & Ying-Zheng Zhao
Didymin is a dietary flavonoid that first found in citrus fruits, and possesses antioxidant properties. Our preliminary experiments first discovered that didymin was able to sensitize the resistant cancer cells against chemotherapeutics and combat multidrug resistance. However, its poor aqueous solubility and resultant low bioavailability limit its potentials as an adjuvant phytochemical drug for chemotherapy. Thus, this study prepared the inclusion complex of didymin with β-cyclodextrin and 2-hydroxypropyl-β-cyclodextrin to improve its bioavailability and then evaluate...

SPA: a peptide antagonist that acts as a cell-penetrating peptide for drug delivery

Jingjing Song, Sujie Huang, Zhengzheng Zhang, Bo Jia, Huan Xie, Ming Kai & Wei Zhang
Although cell-penetrating peptides (CPPs) has been proven to be efficient transporter for drug delivery, ideal peptide vectors for tumor therapy are still being urgently sought. Peptide antagonists have attracted substantial attention as targeting molecules because of their high tumor accumulation and antitumor activity compared with agonists. SPA, a derivative of substance P, is a potent antagonist that exhibits antitumor activity. Based on the amino acid composition of SPA, we speculate that it can translocate across...

Jinggang Cui, Wei Li, Guohua Liu, Xiaojun Chen, Xiaolai Gao, Huiling Lu & Dang Lin
More and more circular RNAs (circRNAs) revealed to play a critical role in the initiation and progression of cancer, however, the effects of circRNAs on non-small cell lung cancer (NSCLC) remain largely undetermined. In the present study, we screened the dysregulated circRNAs in paired NSCLC and normal samples from GEO database and identified circ_0043278 was to be significantly up-regulated in NSCLC and demonstrated it promotes NSCLC progression in vitro and in vivo. Then, we revealed...

Hu Zhao, Xiaofeng Lai, Wei Zhang, Hehuan Zhu, Shenhang Zhang, Weizhen Wu, Shuiliang Wang, Minying Tang, Zhen Deng & Jianming Tan
MicroRNAs (miRNAs) have vastly expanded our view of RNA world in intracellular signal regulating networks. Here, we functionally characterized a normally highly expressed miRNA, miR-30a-5p (MIMAT0000087), which exhibits downregulated expression profiles in prostate cancer samples. MiR-30a-5p knockdown and overexpression in PC-3 cell line alters cell proliferation supporting a tumour suppressor role. We also discovered that PCLAF is the direct target of miR-30a-5p. Notably, PC-3 cell proliferation is inhibited by miR-30a-5p/PCLAF axis. miR-30a-5p represents a novel...

Cholesterol depletion sensitizes gallbladder cancer to cisplatin by impairing DNA damage response

Yonglong Zhang, Yanfeng Liu, Jinlin Duan, Hui Wang, Yuchen Zhang, Ke Qiao & Jian Wang
Gallbladder cancer (GBC) is the common malignancy of the bile tract system with extremely poor clinical outcomes, owing to its metastatic property and intrinsic resistance to the first-line drugs. Although it is well-established that cholesterol abnormity contributes to gallstone formation, a leading risk factor for GBC, the link of cholesterol homeostasis with GBC has not been investigated. The present study systematically examined the genes implicated in cholesterol homeostasis, and revealed altered gene expressions of de...

Yong-Guang Gao, Shu-Yuan Huangfu, Suryaji Patil, Quan Tang, Wan Sun, Yu Li, Zhong-Lin Lu & Airong Qian
A series of multifunctional compounds (MFCs) 1a–1e based on 1,8-naphthalimide and [12]aneN3 building blocks were designed and synthesized. They were used as not only fluorescent probes for recognition of Cu2+ ions but also as non-viral gene vectors for DNA and RNA delivery. Furthermore, their complexes with Cu2+ (1-Cu) could also selectively stain lysosome in HeLa cells. In order to achieve high performance multifunctional materials, structure-performance relationship of MFCs 1a–1e was studied. It was found that...
