The present invention relates to compositions and methods for treating autoimmune, microbial, metabolic, neoplastic, and posttraumatic diseases mediated by inflammation in a subject. Compositions and methods including at least one importin beta-selective nuclear transport modifier (NTM) and/or at least one importin alpha-selective NTM, and/or at least one importin alpha-specific NTM, and/or at least one inhibitor of importin alpha and importin beta complex formation may be administered to a subject to modulate the transport of transcription factors, mediated by nuclear import adaptors, into the nucleus of a cell resulting in a decrease or abrogation of inflammation.

Compositions and methods for targeting nuclear import shuttles and treating inflammatory disorders

Disclosed herein are compositions and methods for inhibiting collagen production mediated by the Fused in Sarcoma (FUS) ribonucleoprotein. As disclosed herein, the C terminal domain of FUS contains an uncommon nuclear localization sequence (NLS) motif called PY-NLS that binds the nuclear import receptor transportin. Phosphorylation of FUS leads to its association with transportin and nuclear translocation with consequent increased in collagen production. Therefore, disclosed herein is an isolated peptide having a transportin-binding moiety, which inhibits FUS from binding transportin, linked to a membrane translocating motif. These compositions and methods can be used to inhibit FUS-mediated collagen production, and treat fibrotic disease involving FUS-mediated collagen accumulation in kidneys and other organs displaying fibrotic diseases.

Fused in sarcoma (FUS) nuclear translocation inhibitors for preventing fibrosis

Disclosed are compositions and methods for treating microbial inflammation including its end-stage sepsis and conditions associated with the microbial inflammation such as thrombocytopenia and hypoglycogenemia. In one aspect, the compositions and methods disclosed herein can also be used to enhance clearance of microbes from infected tissues, organs, or systems in a subject. Also disclosed herein are compositions and methods for reducing levels of stress responsible transcription factors and metabolic transcription factors in a cell in a subject with microbial inflammation.

Methods and compositions for treating microbial inflammation

Disclosed are compositions and methods for treating inflammation including its end-stage sepsis and conditions mediated by inflammation such as liver apoptosis and cirrhosis, thrombocytopenia, hypoglycogenemia, hyperglycemia, and hypertriglyceridemia. In one aspect, the compositions and methods disclosed herein can also be used to enhance clearance of microbes from infected tissues, organs, or systems in a subject. Also disclosed herein are compositions and methods for reducing levels of stress responsible transcription factors and metabolic transcription factors in a cell in a subject with microbial, allergic, autoimmune, metabolic, and posttraumatic inflammation.

Methods and compositions for treating alcoholic liver disease

The present invention relates to compositions and methods for treating diseases associated with dyslipidemia, including hypercholesterolemia, hypertriglyceridemia, steatohepatitis, atherosclerosis, obesity, hyperglycemia, metabolic syndrome, and related aspects of and conditions associated with metabolic syndrome. The compositions and methods disclosed herein are useful for regulating the lipid balance (lipid homeostasis) in a subject. Compositions and methods including a Nuclear Transport Modifier may be administered to a subject to modulate the transport of transcription factors, mediated by nuclear import adaptors, into the nucleus of a cell resulting in a decrease in cholesterol and triglyceride levels in the blood and liver, a decrease in atherosclerotic lesion size, a decrease in body weight and in hyperglycemia, a reduction of fatty liver inflammation, and an improvement in liver function.

Compositions and methods for treating and preventing hyperlipidemia, fatty liver, atherosclerosis and other disorders associated with metabolic syndrome

Nuclear Transport Modifiers such as cSN50 and cSN50.1, afford in vivo islet protection following a 2-day course of intense treatment in autoimmune diabetes-prone, non-obese diabetic (NOD) mice, a widely used model of Type 1 diabetes (T1D), which resulted in a diabetes-free state for one year without apparent toxicity and the need to use insulin. cSN50 precipitously reduces the accumulation of islet-destructive autoreactive lymphocytes while enhancing activation-induced cell death of T and B lymphocytes derived from NOD mice. cSN50 attenuated pro-inflammatory cytokine and chemokine production in immune cells in this model of human T1D. cSN50 also provides cytoprotection of beta cells, therefore preserving residual insulin-producing capacity. Because intracellular delivery of a Nuclear Transport Modifier peptide such as cSN50 and cSN50.1 can result in lowering of fasting blood glucose levels and may ameliorate (e.g., reduce, eliminate) insulin resistance, the compositions, methods and cells described herein can also be used for treating Type 2 diabetes (T2D).
