Abstract
A variety of swine enteric coronaviruses (SECoVs) have emerged and are prevalent in pig populations, including porcine epidemic diarrhea virus (PEDV), transmissible gastroenteritis virus (TGEV), porcine deltacoronavirus (PDCoV), and swine acute diarrhea syndrome (SADS)-CoV, a newly identified bat-origin CoV with zoonotic potential. Unfortunately, available traditional, inactivated and attenuated SECoV vaccines are of limited efficacy against the variants currently circulating in most pig populations. In this study, we evaluated the role of host factor heat shock protein 90 (Hsp90) as an antiviral target against SECoVs, exemplified by SADS-CoV. Pharmacological inhibition of Hsp90 diminished SADS-CoV replication significantly in porcine and human cell lines, and also decreased replication of SADS-CoV in a porcine intestinal enteroid model. Further mechanistic experiments revealed that both porcine and human isoforms of Hsp90 interact with the SADS-CoV nucleocapsid (N) protein, and inhibition of Hsp90 resulted in autophagic degradation of N protein. Moreover, we linked Hsp90 to virus-induced cellular pyroptosis, as SADS-CoV was found to trigger caspase-1/gasdermin-D-mediated pyroptotic cell death, which was mitigated by inhibition of Hsp90. Finally, we demonstrated that Hsp90 also associated with N proteins and was involved in propagation of PEDV, PDCoV and TGEV. This study thus extends our understanding of immune responses to SADS-CoV infection and offers a new potential therapeutic option against four SECoVs.

Abstract
The molecular chaperone heat shock protein 90 (Hsp90) is essential in eukaryotes. Hsp90 chaperones proteins that are important determinants of multistep carcinogenesis. There are multiple Hsp90 isoforms including the cytosolic Hsp90α and Hsp90β as well as GRP94 located in the endoplasmic reticulum and TRAP1 in the mitochondria. The chaperone function of Hsp90 is linked to its ability to bind and hydrolyze ATP. Co-chaperones and posttranslational modifications (such as phosphorylation, SUMOylation, and ubiquitination) are important for Hsp90 stability and regulation of its ATPase activity. Both mammalian and yeast cells can be used to express and purify Hsp90 and TRAP1 and also detect post-translational modifications by immunoblotting.

Abstract
Despite tremendous success of molecular targeted therapy together with immunotherapy, only a small subset of patients can benefit from them. Chemotherapy remains the mainstay treatment for most of tumors including non-small cell lung cancer (NSCLC); however, non-selective adverse effects on healthy tissues and secondary resistance are the main obstacles. Meanwhile, the quiescent or dormant cancer stem-like cells (CSLCs) are resistant to antimitotic chemoradiotherapy. Complete remission can only be realized when both proliferative cancer cells and quiescent cancer stem cells are targeted. In the present research, we constructed a cooperatively combating conjugate (DTX-P7) composed of docetaxel (DTX) and a heptapeptide (P7), which specifically binds to cell surface Hsp90, and assessed the anti-tumor effects of DTX-P7 on non-small cell lung cancer. DTX-P7 preferentially suppressed tumor growth compared with DTX in vivo with a favorable distribution to tumor tissues and long circulation half-life. Furthermore, we revealed a distinctive mechanism whereby DTX-P7 induced unfolded protein response and eventually promoted apoptosis. More importantly, we found that DTX-P7 promoted cell cycle reentry of slow-proliferating CSLCs and subsequently killed them, exhibiting a "proliferate to kill" pattern. Collecitvely, by force of active targeting delivery of DTX via membrane-bound Hsp90, DTX-P7 induces unfolded protein response and subsequent apoptosis by degrading Hsp90, meanwhile awakens and kills the dormant cancer stem cells. Thus, DTX-P7 deserves further development as a promising anticancer therapeutic for treatment of various membrane-harboring Hsp90 cancer types.

Abstract
Background Osimertinib improve therapy for non-small cell lung cancer (NSCLC). However, invariable acquired resistance appears. Methods MTT assay was used to analyze cell viability. Protein expression and activation was detected by Western blotting. In addition, the effects of heat shock protein 90 (Hsp90) inhibitors and osimertinib were studied in colony formation assays. Results Our laboratory generated osimertinib resistant cell lines from PC9 cell line and overexpression or activation of several proteins was detected. Hsp90 inhibitors, ganetespib and luminespib, inhibited cell viability and colony formation in H1975, PC9 and PC9-derived osimertinib-resistant cell lines and combination of these inhibitors with osimertinib achieved to enhance this cell viability and colony formation inhibition. Luminespib downregulated the expression of the several proteins involved in osimertinib-resistance and the combination of this compound plus osimertinib caused an important decrease of expression of several of these proteins, such as Stat3, Yap, Akt, EGFR and Met. Osimertinib activated the phosphorylation of several membrane receptors and downstream molecules that was partially inhibited by luminespib. In addition, a lung cancer patient with an EGFR eon 20 mutation had a partial radiographic response to ganetespib. Conclusions Hsp90 inhibitors and osimertinib exhibits a good efficiency to inhibit cell viability, colony formation and inhibits expression and activation of proteins involved in osimertinib-resistance and may represent an effective strategy for NSCLC with intrinsic resistance to osimertinib inhibition.

Abstract
Hepatitis B virus (HBV) infection can cause chronic liver diseases, cirrhosis, and hepatocellular carcinoma (HCC). Heat shock proteins (Hsps) are important factors in the formation of the HBV capsid and in genome replication during the viral life cycle. Hsp90 is known to promote capsid assembly. However, the functional roles of Hsp70 in HBV capsid assembly with Hsp90 have not been studied so far. Using microscale thermophoresis analyses and in vitro nucleocapsid formation assays, we found that Hsp70 bound to a HBV core protein dimer and facilitated HBV capsid assembly. Inhibition of Hsp70 by methylene blue (MB) led to a decrease in capsid assembly. Moreover, Hsp70 inhibition reduced intracellular capsid formation and HBV virus particle number in HepG2.2.15 cells. Furthermore, we examined synergism between Hsp70 and Hsp90 on HBV capsid formation in vitro. Our results clarify the role of Hsp70 in HBV capsid formation via an interaction with core dimers and in synergistically promoting capsid assembly with Hsp90.

Abstract
The vital importance of the Leloir pathway of galactose metabolism has been repeatedly demonstrated by various uni-/multicellular model organisms, as well human patients who have inherited deficiencies of the key GAL enzymes. Yet, other than the obvious links to the glycolytic pathway and glycan biosynthetic pathways, little is known about how this metabolic pathway interacts with the rest of the metabolic and signaling networks. In this study, we compared the growth and the expression levels of the key components of the PI3K/Akt growth signaling pathway in primary fibroblasts derived from normal and galactose-1 phosphate uridylyltransferase (GalT)-deficient mice, the latter exhibited a subfertility phenotype in adult females and growth restriction in both sexes. The growth potential and the protein levels of the pAkt(Thr308), pAkt(Ser473), pan-Akt, pPdk1, and Hsp90 proteins were significantly reduced by 62.5%, 60.3%, 66%, 66%, and 50%, respectively in the GalT-deficient cells. Reduced expression of phosphorylated Akt proteins in the mutant cells led to diminished phosphorylation of Gsk-3β (-74%). Protein expression of BiP and pPten were 276% and 176% higher respectively in cells with GalT-deficiency. Of the 24 genes interrogated using QIAGEN RT(2) Profiler PCR Custom Arrays, the mRNA abundance of Akt1, Pdpk1, Hsp90aa1 and Pi3kca genes were significantly reduced at least 2.03-, 1.37-, 2.45-, and 1.78-fold respectively in mutant fibroblasts. Both serum-fasted normal and GalT-deficient cells responded to Igf-1-induced activation of Akt phosphorylation at +15 min, but the mutant cells have lower phosphorylation levels. The steady-state protein abundance of Igf-1 receptor was also significantly reduced in mutant cells. Our results thus demonstrated that GalT deficiency can effect down-regulation of the PI3K/Akt growth signaling pathway in mouse fibroblasts through distinct mechanisms targeting both gene and protein expression levels.

Abstract
Alzheimer's disease (EOAD, LOAD), mild cognitive impairment (MCI), Parkinson's disease (PD) and healthy controls were included to determine the serum interleukin-1s (IL-1α, IL-1β), IL-6 and alpha-2-macroglobulin (α2M) levels using ELISA. IL-6 might be a significant contributor to the inflammatory response in LOAD. The MCI data indicate that IL-1s, α2M and BDNF are somehow related, and this relationship might allow MCI patients to be more similar to the healthy controls. A correlation analysis of multiple biomarkers in different neurodegenerative disorders might be more useful than determining the levels of a single cytokine in a single disorder.
