Abstract
Genetic variation in human populations can result in the misfolding and aggregation of proteins, giving rise to systemic and neurodegenerative diseases that require management by proteostasis. Here, we define the role of GRP94, the endoplasmic reticulum Hsp90 chaperone paralog, in managing alpha-1-antitrypsin deficiency on a residue-by-residue basis using Gaussian process regression-based machine learning to profile the spatial covariance relationships that dictate protein folding arising from sequence variants in the population. Covariance analysis suggests a role for the ATPase activity of GRP94 in controlling the N- to C-terminal cooperative folding of alpha-1-antitrypsin responsible for the correction of liver aggregation and lung-disease phenotypes of alpha-1-antitrypsin deficiency. Gaussian process-based spatial covariance profiling provides a standard model built on covariant principles to evaluate the role of proteostasis components in guiding information flow from genome to proteome in response to genetic variation, potentially allowing us to intervene in the onset and progression of complex multi-system human diseases.

Abstract
Disparity in the activity of Endoplasmic reticulum (ER) leads to degenerative diseases, mainly associated with protein misfolding and aggregation leading to cellular dysfunction and damage, ultimately contributing to ER stress. ER stress activates the complex network of Unfolded Protein Response (UPR) signaling pathways mediated by transmembrane proteins IRE1, ATF6, and PERK. In addition to UPR, many ER chaperones have evolved to optimize the output of properly folded secretory and membrane proteins. Glucose-regulated protein 94 (GRP94), an ER chaperone of heat shock protein HSP90 family, directs protein folding through interaction with other components of the ER protein folding machinery and assists in ER-associated degradation (ERAD). Activation of GRP94 would increase the efficacy of protein folding machinery and regulate the UPR pathway toward homeostasis. The present study aims to screen for novel agonists for GRP94 based on Core hopping, pharmacophore hypothesis, 3D-QSAR, and virtual screening with small-molecule compound libraries in order to improve the efficiency of native protein folding by enhancing GRP94 chaperone activity, therefore to reduce protein misfolding and aggregation. In this study, we have employed the strategy of small molecule-dependent ER programming to enhance the chaperone activity of GRP94 through scaffold hopping-based screening approach to identify specific GRP94 agonists. New scaffolds generated by altering the cores of NECA, the known GRP94 agonist, were validated by employing pharmacophore hypothesis testing, 3D-QSAR modeling, and molecular dynamics simulations. This facilitated the identification of small molecules to improve the efficiency of native protein folding by enhancing GRP94 activity. High-throughput virtual screening of the selected pharmacophore hypothesis against Selleckchem and ZINC databases retrieved a total of 2,27,081 compounds. Further analysis on docking and ADMET properties revealed Epimedin A, Narcissoside, Eriocitrin 1,2,3,4,6-O-Pentagalloylglucose, Secoisolariciresinol diglucoside, ZINC92952357, ZINC67650204, and ZINC72457930 as potential lead molecules. The stability and interaction of these small molecules were far better than the known agonist, NECA indicating their efficacy in selectively alleviating ER stress-associated pathogenesis. These results substantiate the fact that small molecule-dependent ER reprogramming would activate the ER chaperones and therefore reduce the protein misfolding as well as aggregation associated with ER stress in order to restore cellular homeostasis.

Abstract
Protein-assembly defects due to an enrichment of aberrant conformational protein variants are emerging as a new frontier in therapeutics design. Understanding the structural elements that rewire the conformational dynamics of proteins and pathologically perturb functionally oriented ensembles is important for inhibitor development. Chaperones are hub proteins for the assembly of multiprotein complexes and an enrichment of aberrant conformers can affect the cellular proteome, and in turn, phenotypes. Here, we integrate computational and experimental tools to investigte how N-glycosylation of specific residues in glucose-regulated protein 94 (GRP94) modulates internal dynamics and alters the conformational fitness of regions fundamental for the interaction with ATP and synthetic ligands and impacts substructures important for the recognition of interacting proteins. N-glycosylation plays an active role in modulating the energy landscape of GRP94, and we provide support for leveraging the knowledge on distinct glycosylation variants to design molecules targeting GRP94 disease-associated conformational states and assemblies.

Abstract
Long non-coding RNAs (lncRNAs) have been implicated in gastric cancer (GC) carcinogenesis and progression. However, the role of LINC00501 in GC growth and metastasis remains unclear. In this study, we found that LINC00501 was frequently upregulated in GC cells and tissues and was closely related to adverse GC clinicopathological features. Aberrant overexpression of LINC00501 promoted GC cell proliferation, invasion, and metastasis both in vitro and in vivo. Mechanistically, LINC00501 stabilized client protein STAT3 from deubiquitylation by directly interacting with cancer chaperone protein HSP90B1. Furthermore, the LINC00501-STAT3 axis modulated GC cell proliferation and metastasis. In turn, STAT3 bound directly to the LINC00501 promoter and positively activated LINC00501 expression, thus forming a positive feedback loop, thereby accelerating tumor growth, invasiveness, and metastasis. In addition, LINC00501 expression was positively correlated with STAT3 and p-STAT3 protein expression levels in gastric clinical samples. Our results reveal that LINC00501 acts as an oncogenic lncRNA and that the LINC00501-HSP90B1-STAT3 positive feedback loop contributes to GC development and progression, suggesting that LINC00501 may be a novel potential biomarker and treatment target for GC.

Abstract
Grp94 is the endoplasmic reticulum paralog of the hsp90 family of chaperones, which have been targeted for therapeutic intervention via their highly conserved ATP binding sites. The design of paralog-selective inhibitors relies on understanding the structural elements that mediate each paralog's response to inhibitor binding. Here, we determined the structures of Grp94 and Hsp90 in complex with the Grp94-selective inhibitor PU-H36, and of Grp94 with the non-selective inhibitor PU-H71. In Grp94, the 8-aryl moiety of PU-H36 is inserted into Site 2, a conditionally available side pocket, but in Hsp90 it occupies Site 1, a non-selective side pocket that is accessible in all hsp90 paralogs. The structure of Grp94 in complex with the non-selective PU-H71 shows only Site 1 binding. Large conformational shifts involving helices 1, 4 and 5 of the N-terminal domain of Grp94 are associated with the engagement of the Site 2 pocket for ligand binding. To understand the origins of Site 2 pocket engagement, we tested the binding of Grp94-selective ligands to chimeric Grp94/Hsp90 constructs. These studies show that helix 1 of the Grp94 N-terminal domain is the discriminating element that allows for remodeling of the ATP binding pocket and exposure of the Site 2 selective pocket.

Abstract
The 94 kDa molecular chaperone, glucose-regulated protein 94 (Grp94), has garnered interest during the last decade due to its direct association with endoplasmic reticulum (ER) stress and disease. Grp94 belongs to the Hsp90 family of molecular chaperones and is a master regulator of ER homeostasis due to its ability to fold and stabilize proteins/receptors, and to chaperone misfolded proteins for degradation. Multiple studies have demonstrated that Grp94 knockdown or inhibition leads to the degradation of client protein substrates, which leads to disruption of disease-dependent signaling pathways. As a result, small molecule inhibitors of Grp94 have become a promising therapeutic approach to target a variety of disease states. Specifically, Grp94 has proven to be a promising target for cancer, glaucoma, immune-mediated inflammation, and viral infection. Moreover, Grp94-peptide complexes have been utilized effectively as adjuvants for vaccines against a variety of disease states. This work highlights the significance of Grp94 biology and the development of therapeutics that target this molecular chaperone in multiple disease states.

Abstract
BACKGROUND Nasopharyngeal carcinoma (NPC) is highly prevalent in southern China. The remote metastasis of advanced NPC requires chemotherapeutic treatments to reduce the mortality. Our previous work revealed that saucerneol (SN) showed cytotoxicity against several nasopharyngeal carcinoma (NPC) cells. This work aims to investigate the effect of SN in NPC growth and exploring the mechanism of action. STUDY DESIGN Applying in vivo study, in vitro study and in silico study to indicate the mechanism of SN in inhibiting NPC growth. METHODS Saucerneol (SN) toxicity was measured with MTT assay. NPC proliferation was measured with EdU and colony formation assays, cell cycle was detected with flow cytometry. NPC migration and invasion were measured with scratch assay and matrigel transwell method. Further, human NPC xenograft tumor models were established in nude mice to evaluate the therapeutic efficacy of SN in vivo. Toxicological analysis was performed on H&E staining and IHC. Quantitative real-time PCR and Western blot analyses were used to evaluate the expression levels of key molecules in PI3K/AKT/mTOR, MAPK, NF-κB, and HIF-1α signal pathways. Target predicting was conducted using computational method, and target identification was carried out by ATPase assay and TSA. RESULTS SN, a potent NPC inhibitor that was previously isolated from Saururus chinensis in our lab, is proven to inhibit the proliferation and metastasis of HONE1 cell lines and inhibit the growth of human NPC xenografts in nude mice. Moreover, we further articulate the molecular mechanism of action for SN and, reveal that SN promotes the expression of cell cycle-dependent kinase inhibitory protein p21 Waf1/Cip1 through targeting Grp94 and then inhibiting PI3K/AKT signaling pathway as well as up-regulating p53 to disrupt the progression of HONE1 cells. CONCLUSION SN significantly inhibits NPC cells proliferation and metastasis in vitro and in vivo via selectively inhibit Grp94 and then blocking PI3K/AKT/mTOR/HIF-1α signaling pathway. This study firstly provides a novel selective Grp94 inhibitor as a NPC candidate.

Abstract
Malaria is still one of the major killer parasitic diseases in tropical settings, posing a public health threat. The development of antimalarial drug resistance is reversing the gains made in attempts to control the disease. The parasite leads a complex life cycle that has adapted to outwit almost all known antimalarial drugs to date, including the first line of treatment, artesunate. There is a high unmet need to develop new strategies and identify novel therapeutics to reverse antimalarial drug resistance development. Among the strategies, here we focus and discuss the merits of the development of antimalarials targeting the Heat shock protein 90 (Hsp90) due to the central role it plays in protein quality control.

Abstract
The heat shock protein 90 kDa (Hsp90) family of chaperones is highly sought-after for the treatment of cancer and neurodegenerative diseases. Glucose regulated protein 94 (Grp94) is the endoplasmic reticulum localized isoform that is responsible for the maturation of proteins involved in cell adhesion and the immune response, including Toll-like receptors, immunoglobulins, and integrins. Consequently, Grp94 has been implicated in many different diseases including cancer metastasis, glaucoma, and viral infection. 5'-(N-Ethylcarboxamido)adenosine (NECA) was identified from a high-throughput screen as one of the first molecules to exhibit isoform selectivity toward Grp94, with the ethyl group projecting into a unique pocket within the ATP binding site of Grp94. This pocket has since been exploited by several groups to develop Grp94 selective inhibitors. Despite success in the development of other classes of inhibitors, relatively little work has been done to further develop inhibitors with the NECA scaffold. Unfortunately, NECA is also a potent adenosine receptor agonist, which is likely to confound any biological activity. Therefore, structure-activity relationship studies were performed on the NECA scaffold leading to the discovery of several molecules that displayed similar selectivity and affinity as the parent compound.

Abstract
The molecular chaperone heat shock protein 90 (Hsp90) is a promising target for cancer therapy. Natural product aconitine is a potential Hsp90 inhibitor reported in our previous work. In this study, we designed and synthesized a series of 2-((1-phenyl-1H-1,2,3-triazol-4-yl)methyl)-2-azabicyclo[3.2.1]octan-3-one derivatives as potent Hsp90 inhibitors by simplifying and modifying aconitine scaffold. Among these compounds, 14t exhibited an excellent antiproliferative activity against LoVo cells with an IC50 value of 0.02 μM and a significant Hsp90α inhibitory activity with an IC50 value of 0.71 nM. Molecular docking studies provided a rational binding model of 14t in complex with Hsp90α. The following cell cycle and apoptosis assays revealed that compound 14t could arrest cell cycle at G1/S phase and induce cell apoptosis via up-regulation of bax and cleaved-caspase 3 protein expressions while inhibiting the expressions of bcl-2. Moreover, 14t could inhibit cell migration in LoVo and SW620 cell lines. Consistent with in vitro results, 14t significantly repressed tumor growth in the SW620 xenograft mouse model.

Abstract
We synthesized affinity-based chemical probes of cytosine-adenosine bisubstrate analogs and identified several potential targets by proteomic analysis. The validation of the proteomic analysis identified the chemical probe as a specific inhibitor of glucose-regulated protein 94 (GRP94), a potential drug target for several types of cancers. Therefore, as a result of the use of bisubstrate-type chemical probes and a chemical-biology methodology, this work opens the way to the development of a new family of GRP94 inhibitors that could potentially be of therapeutic interest.
