Summary: The increased and sustained expression of TCblR in proliferating cells has been used to target toxins preferentially to cancer cells and can be potentially used for targeted delivery of other anti-cancer drugs. In 2010 the authors published a paper which evaluated the potential of using immunotoxins to eliminate cancer cells expressing TCblR the authors performed a series of in vitro experiments using their monoclonal antibody plus Mab-ZAP in varying concentrations. The results indicated that this is a viable therapeutic model that causes minimal peripheral damage.

Summary: The authors review the most current mAb-based therapies against EphA2-expressing cancers currently in pre-clinical and/or clinical stages. They reference Sakamoto et al. who performed in vitro testing of two different EphA2 mAbs mixed with Mab-ZAP to discover their therapeutic potential against melanoma.

Summary: Ablation of norepinephrine containing projections to the arcuate (via Anti-DBH-SAP injections) alters AgRP and neuropeptide (NPY) concentrations, leading to impairments in hypoglycemic (glucoprivic) or ghrelin-induced feeding.

Usage: Anti-DBH-SAP (bilateral 42-ng intracranial injections) was used in rats to investigate the role of hindbrain catecholamine afferents in increased ARC NPY and AgRP gene expression.

Objective: To evaluate therapeutic potential of ALPPL2 targeting.

Summary: Exquisite tissue specificity and broad tumor type coverage suggest that ALPPL2 could be an excellent cell surface target for therapeutic development against mesothelioma.

Usage: Biotinylated M25 IgG1 and Streptavidin-ZAP were mixed at a molar ratio of 1:1.

Objective: To determine whether Chlorotoxin-conjugated Saporin (CTX-SAP) would inhibit the growth of aggressive thyroid cancer cell lines expressing MMP-2.

Summary: This in vitro study demonstrated the efficacy of a CTX-SAP conjugate in reducing the viability of ML-1 thyroid cancer cells in a dose dependent manner.

Usage: There was a statistically significant reduction in cell viability with increasing concentrations of the CTX-SAP conjugate (biotinylated Chlorotoxin mixed with Streptavidin-ZAP). The cell viability of ML-1 cells was decreased by 49.77% with the treatment of 600 nM of CTX-SAP (F=44.24). Unconjugated Chlorotoxin or Saporin had no significant effect on cell viability a using similar assay.

Objective: To investigate the role of ADSL hydroxylation in controlling cMYC and triple negative breast cancer (TNBC) tumorigenesis.

Summary: ADSL regulates cMYC protein level through adenosine levels and leads to downstream metabolic changes and breast cancer cell proliferation. ADSL is essential for TNBC cell growth and invasiveness and contributes to TNBC breast tumorigenesis and metastasis in vivo.
