Pan-mTOR inhibitor MLN0128 is effective against intrahepatic cholangiocarcinoma in mice

3 views | Nov 08 2019

Zhang S et al. suggested that mTOR kinase inhibitors may be beneficial for the treatment of ICC, even in tumors that are resistant to standard of care chemotherapeutics, such as gemcitabine/oxaliplatin-based regimens, especially in the subset of tumors exhibiting activated AKT/mTOR cascade. Lay summary: We established a novel mouse model of intrahepatic cholangiocarcinoma (ICC). Using this new preclinical model, we evaluated the therapeutic potential of mTOR inhibitor MLN0128 vs. gemcitabine/oxaliplatin (the standard chemotherapy for ICC treatment). Our study shows the anti-neoplastic potential of MLN0128, suggesting that it may be superior to gemcitabine/oxaliplatin-based chemotherapy for the treatment of ICC, especially in the tumors exhibiting activated AKT/mTOR cascade.

Dual mTORC1/2 inhibition by INK-128 results in antitumor activity in preclinical models of osteosarcoma

0 views | Nov 08 2019

Jiang H et al. showed that INK-128 exerts potent anti-OS activity in vitro and in vivo. INK-128 might be further investigated as a novel anti-OS agent. [Read the Full Post]

AZD2014, an Inhibitor of mTORC1 and mTORC2, Is Highly Effective in ER+ Breast Cancer When Administered Using Intermittent or Continuous Schedules

0 views | Nov 01 2019

Guichard SM et al. indicated the ability to dose AZD2014 intermittently, together with its ability to block signaling from both mTORC1 and mTORC2 complexes, makes this compound an ideal candidate for combining with endocrine therapies in the clinic. AZD2014 is currently in phase II clinical trials. [Read the Full Post]

Intra-articular injection of Torin 1 reduces degeneration of articular cartilage in a rabbit osteoarthritis model

6 views | Oct 30 2019

Cheng NT et al. demonstrated that intra-articular injection of Torin 1 reduces degeneration of articular cartilage in collagenase-induced OA, at least partially by autophagy activation, suggesting a novel therapeutic approach for preventing cartilage degeneration and treating OA.Cite this article: N-T. Cheng, A. Guo, Y-P. Cui. Intra-articular injection of Torin 1 reduces degeneration of articular cartilage in a rabbit osteoarthritis model. [Read the Full Post]

Clinical relevance of a CD4+ T cell immune function assay in the diagnosis of infection in pediatric living-donor liver transplantation

0 views | Oct 14 2019

Liu W et al. suggested that low CD4+ T lymphocyte ATP levels may be an independent risk factor for infection following pediatric LDLT, and that the Immuknow assay may be used as a tool to evaluate T lymphocyte function in such patients to predict the risk of infection. [Read the Full Post]

Effects of EF-24, RAD001, and paclitaxel on the expression profiles of apoptotic and anti-apoptotic genes

0 views | Aug 26 2019

Alp E et al. showed that response of these cells to paclitaxel, EF-24, and RAD001 was found different at the transcriptional level of apoptotic and antiapoptotic genes. Therefore, understanding transcriptional changes after these drug exposure may give us a change to figure out more realistic results of the apoptotic pathway inhibition. [Read the Full Post]

Rapamycin: An InhibiTOR of Aging Emerges From the Soil of Easter Island

66 views | Jul 21 2019

Arriola Apelo SI et al. discuss recent advances in understanding the molecular and physiological effects of rapamycin treatment, and we discuss how the use of alternative rapamycin treatment regimens or rapamycin analogs has the potential to mitigate the deleterious side effects of rapamycin treatment by more specifically targeting mTORC1. Although the side effects of rapamycin are still of significant concern, rapid progress is being made in realizing the revolutionary potential of rapamycin-based therapies for the treatment of diseases of aging.

CCI-779 (Temsirolimus) exhibits increased anti-tumor activity in low EGFR expressing HNSCC cell lines and is effective in cells with acquired resistance to cisplatin or cetuximab

65 views | May 27 2019

Niehr F et al. indicated that activity of CCI-779 in HNSCC cells harboring TP53 mutations and displaying a phenotype of cisplatin resistance suggests its clinical potential even in patients with dismal outcome after current standard treatment. Cetuximab/mTORi combinations might be useful for treatment of tumors with high expression of EGFR/p-EGFR and/or acquired cetuximab resistance. This combinatorial treatment modality needs further evaluation in future translational and clinical studies. [Read the Full Post]

Puromycin based inhibitors of aminopeptidases for the potential treatment of hematologic malignancies
