Podoplanin: An emerging cancer biomarker and therapeutic target

Podoplanin (PDPN) is a transmembrane receptor glycoprotein that is upregulated on transformed cells, cancer associated fibroblasts (CAFs), and inflammatory macrophages that contribute to cancer progression. This review describes recent advances in how PDPN may be used as a biomarker and therapeutic target for many types of cancer including glioma, squamous cell carcinoma, mesothelioma, and melanoma.

Anti-human SIRPα antibody is a new tool for cancer immunotherapy

A blocking mAb to human SIRPα significantly enhanced the inhibitory effect of rituximab on the growth of tumors formed by Burkitt's lymphoma Raji cells in immunodeficient mice engineered to express human SIRPα.The survival of tumor-bearing mice treated with both the mAb and rituximab was also markedly prolonged in comparison with that of those treated with either Ab alone. Our results thus suggest that the combination of Abs to human SIRPα with therapeutic Abs specific for tumor antigens warrants further investigation for potential application to cancer immunotherapy.

Development of a vaccine based on bacteria-mimicking tumor cells coated with novel engineered toll-like receptor 2 ligands

We designed two novel lipopeptides as anti-tumor immunoadjuvants that can coat tumor cell surfaces. Tumor cells coated with these engineered lipopeptides (called bacteria-mimicking tumor cells) promoted DC phagocytosis and antigen cross-presentation via TLR2 and induced the strong anti-tumor effect.

Sonodynamic therapy-assisted immunotherapy: A novel modality for cancer treatment

HiPorfin (HPD)-induced SDT killed tumor cells, promoted calreticulin expression on the cell surface and provoked immune responses. Meanwhile, we observed functional antitumor vaccination and the abscopal effect as a result of SDT in H22 tumor-bearing mice. Furthermore, this strategy conferred an immunological memory, which could protect against tumor recurrence after elimination of the initial tumor.

LKB1 obliterates Snail stability and inhibits pancreatic cancer metastasis in response to metformin treatment

LKB1 is negatively correlated with Snail at protein level in pancreatic cancer (PC). Loss of LKB1 promotes PC's metastasis via elevating Snail protein in AMPK-independent pathway. LKB1 enhances E3 ligase FBXL14 to interact with Snail protein, leading to increasing ubiquitin-mediated Snail degradation Metformin inhibits metastasis through LKB1-mediated Snail ubiquitination in PC cells.

Established gastric cancer cell lines transplantable into C57BL/6 mice show fibroblast growth factor receptor 4 promotion of tumor growth

C57BL/6 mouse transplantable C57BL/6 mouse gastric cancer cell lines were established. These cell lines would be useful for analysis of the molecular function of trans-gene or knockout in a C57BL/6 mouse background, and gastric cancer immune therapy. Identification of the efficacy of FGFR4 blockade is a pertinent example of how these mouse cancer lines can be used for analyzing the effectiveness of cancer therapy.

Ribosome display and selection of single-chain variable fragments effectively inhibit growth and progression of microspheres in vitro and in vivo

This study demonstrated that the scFvs from dynamic screening by ribosome display in a natural state could result in high-affinity evolution to recognize the microspheres. The scFvs could effectively inhibit the microspheres’ collective growth and invasion through targets that might be CD44+/CD24+. When combined with chemotherapy, the scFvs exhibited enhancement of their high-affinity efficiency in inhibiting the proliferation and invasion of microspheres in vitro and in vivo.

Cytotoxic T lymphocyte response to peptide vaccination predicts survival in stage III colorectal cancer

Vaccination-induced immune response could improve prognosis of HLA-A* 2402-positive patients and immune responses that occur shortly after initiating therapy could be used to predict the therapeutic effect. In addition, an HLA-A status double-blind biologically randomized study, what we call “HLA key open method”, could have some limitations due to potential cross-reactivity of the peptides to other serotypes.

Fluorescence tumor imaging by i.v. administered indocyanine green in a mouse model of colitis-associated colon cancer

The present study demonstrated that fluorescence contrast-enhanced imaging following intravenously administered indocyanine green (ICG), a fluorescent contrast agent, can be applied to the detection of colon tumors in a mouse colitis-associated colon cancer model. The tumor tissue preference of ICG in the present model can be attributed to the enhanced vascular leakage of ICG involving inflammatory mediators, such as COX-2 and iNOS, in conjunction with increased tumor vascularity.

c-Src inhibitor selectively inhibits triple-negative breast cancer overexpressed Vimentin in vitro and in vivo

Triple-negative breast cancer (TNBC) is the most intractable subgroup as, so far, there are no effective targeted drugs. Studies indicated that TNBC has shown high sensitivity to c-Src inhibitor in vitro but is of limited benefit in clinical tests. Our study showed that vimentin is a crucial molecule to affect the therapeutic effects of the c-Src inhibitor in TNBC, and it provides an important rationale for the clinic to precisely select TNBC patients who would benefit from c-Src inhibitor treatment.

Angioimmunoblastic T-cell lymphoma (AITL) is a distinct subtype of nodal peripheral T-cell lymphoma (PTCL). Somatic RHOA mutations, (most frequently c.G50T, p.G17V RHOA mutation) are a genetic hallmark of AITL. Our results showed that a combination of NGS, ddPCR and PNA-LNA clamp methods increased the detection rate of RHOA mutations at the p.G17 position.
