Natural products (NPs) are a promising source of anti-inflammatory molecules for the development of drugs. Despite there being an abundance of reports of large numbers of NPs having bioactivity in preliminary cell-based assays of anti-inflammatory potential, their further optimization and exploration is limited by lack of a comprehensive understanding of their effective scaffold structure or biological targets. To facilitate target-based studies of anti-inflammatory NPs, the details of 665 NPs reported to have anti-inflammatory activity were extracted from the literature and compiled into a dataset we termed InflamNat.

Purpose: Cancer immunotherapy is a potent treatment modality, but its clinical benefit depends on the tumor's immune profile. Here, we employed mJX-594 (JX), a targeted and GM-CSF-armed oncolytic vaccinia virus, as a strategy to remodel the tumor microenvironment (TME) and subsequently increase sensitivity to αPD-1 and/or αCTLA-4 immunotherapy.
Experimental Design: The remodeling of TME was determined using histologic, flow cytometric, and NanoString immune profiling analyses. Read More

Defects in apoptotic cell death can promote cancer and impair responses of malignant cells to anti-cancer therapy. Pro-survival BCL-2 proteins prevent apoptosis by keeping the cell death effectors, BAX and BAK, in check. The BH3-only proteins initiate apoptosis by neutralizing the pro-survival BCL-2 proteins.

Prostate cancer (CaP) is the second most common cancer in men worldwide in 2012, and radiation therapy is one of the most common definitive treatment options for localized CaP. However, radioresistance is a major challenge for the current radiotherapy, accumulating evidences suggest microRNAs (miRNAs), as an important regulator in cellular ionizing radiation (IR) responses, are closely correlated with radiosensitivity in many cancers. Here, we identified microRNA-16-5p(miR-16-5p) is significantly upregulated in CaP LNCaP cells following IR and can enhance radiosensitivity through modulating Cyclin D1/E1-pRb-E2F1 pathway. Read More

Purpose: Gastrointestinal stromal tumor (GIST) is a common type of soft tissue sarcoma. Imatinib, an inhibitor of KIT, PDFGRA and a few other tyrosine kinases, is highly effective for GIST, but advanced GISTs frequently progress on imatinib and other approved tyrosine kinase inhibitors. We investigated phosphodiesterase 3 (PDE3) as a potential therapeutic target in GIST cell lines and xenograft models. Read More

Significant synergy of doxorubicin (DOX) and glycyrrhizic acid (GA) in inhibiting the proliferation of cancer cells was demonstrated in the human hepatocellular carcinoma cell line, HepG2. A novel polymeric prodrug micellar carrier based on polyethylene glycol-derivatized GA (PEG-Fmoc-GA), was developed for co-delivery of DOX as a combined anti-cancer treatment. The PEG-Fmoc-GA polymeric prodrug micelles achieved a more effective synergistic action on cell proliferation inhibition and apoptosis induction, when co-delivered with DOX, which can be attributed to the dual effect of the cleaved GA and loaded DOX.

So far, the success of anticancer nanomedicines has been moderate due to their lack of adequate targeting properties and/or to their difficulties penetrating tumors. Here we report a multifunctional drug nanocarrier consisting of hyaluronic acid nanocapsules conjugated with the tumor homing peptide tLyp1, which exhibits both, dual targeting properties (to the tumor and to the lymphatics), and enhanced tumor penetration. Data from a 3D co-culture in vitro model showed the capacity of these nanocapsules to interact with the NRP1 receptors over-expressed in cancer cells. Read More

Inhibition of the hedgehog (Hh) signaling pathway has been validated as a therapeutic strategy to treat basal cell carcinoma and holds potential for several other forms of human cancer. Itraconazole and posaconazole are clinically useful triazole anti-fungals that are being repurposed as anti-cancer agents based on their ability to inhibit the Hh pathway. We have previously demonstrated that removal of the triazole from itraconazole does not affect its ability to inhibit the Hh pathway while abolishing its primary side effect, potent inhibition of Cyp3A4.

In the last decade, it has become clear that anti-cancer therapy is more successful when it can also induce an immunogenic form of cancer cell death (ICD). ICD is an umbrella term covering several cell death modalities, including apoptosis and necroptosis. In general, ICD is characterized by the emission of damage-associated molecular patterns (DAMPs) and/or cytokines/chemokines, leading to the induction of strong anti-tumor immune responses. Read More

Background: Ubiquitin-proteasome system (UPS) is integral to cell survival by maintaining protein homeostasis, and its dysfunction has been linked to cancer and several other human diseases. Through counteracting ubiquitination, deubiquitinases (DUBs) can either positively or negatively regulate UPS function, thereby representing attractive targets of cancer therapies. Previous studies have shown that metal complexes can inhibit tumor growth through targeting the UPS; however, novel metal complexes with higher specificity for cancer therapy are still lacking.

Inhibition of normal cellular apoptosis or programed cell death is the hallmark of all cancers. Apoptotic dysregulation can result in numerous pathological conditions, such as cancers, autoimmune disorders, and neurodegeneration. Members of the BCL-2 family of proteins regulate the process of apoptosis by its promotion or inhibition and overexpression of the pro-survival anti-apoptotic proteins (Bcl-2, Bcl-xL, and Mcl-1) has been associated with tumor maintenance, growth and progression Small molecules and peptides which bind the BH3 binding groove of these proteins have been explored in the recent times for their anticancer potential.

In this study changes in thymidine kinase 1 (TK1) levels after 24 hours of Doxorubicin (Dox) exposure of CEM and MDA MB-231 cells were determined using the commercially available AroCell TK 210 ELISA test. In cell extracts, TK1 levels increased twofold with 1 µM Dox in both cell lines, while the TK1 levels in the culture media increased with 5 and 10 µM of Dox only in case of CEM cells. In conclusion, this study reveals that the TK 210 ELISA can measure changes in intra- and extracellular TK1 levels apparently related to the mechanism of cytotoxicity of anti-cancer agents. Read More

Designing new drug delivery systems (DDSs) for safer cancer therapy during pre-clinical and clinical applications still constitutes a considerable challenge, despite advances made in related fields. Lipid-based drug delivery systems (LBDDSs) have emerged as biocompatible candidates that overcome many biological obstacles. In particular, a combination of the merits of lipid carriers and functional polymers has maximized drug delivery efficiency. Read More
