Preventing Candida albicans from subverting host plasminogen for invasive infection treatment

Si-Min Chen, Zui Zou, Shi-Yu Guo, Wei-Tong Hou, Xi-Ran Qiu, Yu Zhang, Li-Jun Song, Xin-Yu Hu, Yuan-Ying Jiang, Hui Shen & Mao-Mao An
Candida albicans is a common fungal pathogen in humans that colonizes the skin and mucosal surfaces of the majority healthy individuals. How C. albicans disseminates into the bloodstream and causes life-threatening systemic infections in immunocompromised patients remains unclear. Plasminogen system activation can degrade a variety of structural proteins in vivo and is involved in several homeostatic processes. Here, for the first time, we characterized that C. albicans could capture and “subvert” host plasminogen to invade...

PtdIns4P restriction by hydrolase SAC1 decides specific fusion of autophagosomes with lysosomes

Hongjun Zhang, Jiao Zhou, Peng Xiao, Yong Lin, Xin Gong, Shiyan Liu, Qingjia Xu, Minjin Wang, Haiyan Ren, Mengji Lu, Yuan Wang, Jing Zhu, Zhiping Xie, Huihui Li & Kefeng Lu
Biogenesis of autophagosomes is the early step of macroautophagy/autophagy and requires membrane acquisition mainly from ER-Golgi-sourced precursor vesicles. Matured autophagosomes fuse with lysosomes for final degradation. However, how this selective fusion is determined remains elusive. Here, we identified Sac1 by a high throughput screen in Saccharomyces cerevisiae to show it was critical for autophagosome-lysosome fusion through its PtdIns4P phosphatase activity. Sac1 deficiency caused a dramatic increase of PtdIns4P at early Golgi apparatus and abnormal incorporation...

Mice deficient in UXT exhibit retinitis pigmentosa-like features via aberrant autophagy activation

Mingyu Pan, Yue Yin, Xinxia Wang, Quanyi Wang, Lele Zhang, Haiyang Hu & Chen Wang
UXT (ubiquitously expressed prefoldin like chaperone), a small chaperone-like protein, is widely expressed in diverse human and mouse tissues and is more abundant in retina and kidney. However, the functional characterization of UXT at tissue level was largely unknown. Here, we reported that mice deficient in UXT exhibited salient features of retinal degenerative disease, similar to retinitis pigmentosa. Conditional knockout (CKO) of Uxt led to retinal degeneration and pigmentation in mice retina along with significant...

A novel four-gene of iron metabolism-related and methylated for prognosis prediction of hepatocellular carcinoma

Huimin Shen, Hao Wu, Fengkai Sun, Jianni Qi & Qiang Zhu
Hepatocellular carcinoma (HCC) is a liver disease with a complex underlying mechanism, and patients with HCC have low survival rates. Iron metabolism plays a crucial role in the pathogenesis of HCC; however, the prognostic value of iron metabolism-related and methylated genes for HCC needs to be further explored. In the present study, we identified differentially expressed genes (DEGs) that play a role in iron metabolism and DNA methylation in HCC from The Cancer Genome Atlas....

Transcriptomic characteristics of bronchoalveolar lavage fluid and peripheral blood mononuclear cells in COVID-19 patients

Yong Xiong, Yuan Liu, Liu Cao, Dehe Wang, Ming Guo, Ao Jiang, Dong Guo, Wenjia Hu, Jiayi Yang, Zhidong Tang, Honglong Wu, Yongquan Lin, Meiyuan Zhang, Qi Zhang, Mang Shi, Yingle Liu, Yu Zhou, Ke Lan & Yu Chen
Circulating in China and 158 other countries and areas, the ongoing COVID-19 outbreak has caused devastating mortality and posed a great threat to public health. However, efforts to identify effectively supportive therapeutic drugs and treatments has been hampered by our limited understanding of host immune response for this fatal disease. To characterize the transcriptional signatures of host inflammatory response to SARS-CoV-2 (HCoV-19) infection, we carried out transcriptome sequencing of the RNAs isolated from the bronchoalveolar...
