- Chronic cadmium exposure is linked to esophageal squamous cell carcinoma (ESCC) progression, treatment resistance, and poor prognosis, but its molecular mechanisms remain unclear. Based on whole-transcriptome sequencing (RNA-seq) on chronic cadmium-treated (CCT) and untreated human EC109 ESCC cells, we performed lncRNA-mRNA co-expression and protein-protein interaction (PPI) network analyses to screen the hub genes related to cadmium exposure. Then, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses depicted that these genes were mainly enriched in nucleocytoplasmic transport, ferroptosis, Huntington disease, and cellular senescence. Based on the lncRNA-miRNA-mRNA potential interaction, three lncRNAs (AC107068.1, TTN-AS1, MAPKAPK5-AS1) and ten mRNAs (IPO5, NUDCD1, OSTM1, CCNB1, FANCD2, TFRC, POLR2B, HTT, NUP43, NBN) were selected for competitive endogenous RNA (ceRNA) network construction. Connectivity map (CMap) analysis for the target mRNAs showed that JAK3-inhibitor-I was the most promising therapeutic drug for cadmium-induced ESCC progression. The prognostic value and abnormal expression of the candidate mRNAs were then validated in TCGA cohorts, cadmium-treated cancer cells and 41 ESCC specimens. Moreover, migration and invasion assays were performed to assess the effects of the identified gene on cell malignant phenotypes. As a result, IPO5 was identified as the pivotal gene and MAPKAPK5-AS1-hsa-miR-379-5p-IPO5 was deemed as a potential ceRNA regulatory mechanism for cadmium carcinogenesis in ESCC. Using TIMER and EPIC algorithms, IPO5 was correlated with increased infiltration of CD4 T cells and macrophages, while negatively associated with CD8 T cells and NK cells in ESCC tissues. Collectively, our study provides valuable information in understanding the molecular mechanisms involved in cadmium-induced ESCC progression and treatment resistance. Furthermore, we predict potential agents for cadmium carcinogenicity prevention and treatment. - Source: PubMed

Zhu RuiChen JiongyuZhang XiarongChen QianJin YingmingZeng MingqinLuo JiananHuang YitengPeng Lin - The highly conserved nuclear transport protein importin 5 (IPO5) binds cargo implicated in fundamental processes including virus and chromatin assembly, germline development, and cell signaling. It also anchors cell-specific cargo for functional outcomes in development and immune responses. IPO5 displays both spatial and temporal regulation in the male germline, from fetal through to adult ages. Because it transports key early developmental/reproductive factors, including Stella and the BMP signaling SMADs 1/5/9, we hypothesized that targeted IPO5 deletion would impair germline development and viability at specific stages. Here, we demonstrate in vivo functional importance of IPO5 by generating global and conditional IPO5 knockout mice using an Ipo5FL/FL allele flanking exons 9 and 10. Global deletion using CMVCre produced no null embryos at embryonic day (E)12.5, while heterozygous embryo numbers were reduced to 50%, demonstrating it is essential for early embryogenesis. A sex-specific germline requirement for IPO5 was demonstrated following deletion using VasaCre (active from E15.5); adult testes lacked germ cells, while oocytes developed and female fertility was unaffected. Stra8Cre-directed IPO5 deletion (active from postnatal day (PND) 3) caused meiotic failure evident at PND 14; no IPO5-deficient germ cells were present in adults, although niche integrity and function supported emergence of rare IPO5-positive spermatozoa. Novel IPO5 binding proteins identified by immunoprecipitation and mass-spectrometry included SFPQ in fetal testes and XPO2 (exportin 2) in both isolated spermatocytes and spermatids. Remarkably, most IPO5 potential binding proteins are essential for male fertility. These results define IPO5 as crucial for in vivo embryonic development and male fertility. - Source: PubMed

Authors Listed N - Sphingosine and constrained analogs like FTY720 and SH-BC-893 restrain tumor growth through incompletely defined mechanisms that include protein phosphatase 2A (PP2A) activation. Here we show that these compounds directly bind not only the PP2A scaffolding subunit PPP2R1A, but also the structurally related karyopherins importin-β1 (KPNB1), transportin-1 (TNPO1), importin-5 (IPO5), and importin-7 (IPO7). Binding to sphingosine-like molecules triggers reversible unfolding of these target proteins, resulting in activation of PP2A and inhibition of importins. Although sphingosine engages these proteins, ceramide does not, suggesting that these two endogenous tumor-suppressive sphingolipids work through distinct mechanisms. Simultaneous PP2A activation and importin inhibition reduces nuclear levels of proteins that drive cancer progression and therapeutic resistance such as JUN, YAP, MYC, androgen receptor, hnRNPA1, and NF-κB under conditions where compounds that target PP2A or KPNB1 individually are inactive. These findings provide new insights into sphingolipid biology and highlight a possible path toward cancer therapeutics that could overcome drug resistance. - Source: PubMed

Thus, during infection, newly synthesized RNA polymerase subunits must be imported into the nucleus. Although several models have been proposed for this process, the consensus is that the RNA polymerase subunits PB1 and PA form a dimer in the cytoplasm and are transported into the nucleus by Ran binding protein 5 (RanBP5). The PB2 subunit undergoes separate transport to complete the nuclear import. However, the molecular mechanism of nuclear import by host factors and their interactions with proteins are largely unknown. Here we present the structural analysis of the RanBP5 and PB1 NLS domain complex by cryo-EM at 3.2 Å resolution. The pattern shows that the NLS domain of PB1 does not exist in a secondary structure and interacts with RanBP5 in a wrapped state. In addition, biochemical analyses of the mutant have identified critical amino acid sites involved in complex binding. The results suggest a stepwise assembly of influenza virus structural components regulated by nuclear import mechanisms and host factor binding, with important implications for drug discovery research. - Source: PubMed
