Radioimmunotherapy offers an effective way to direct ionizing radiation to cancer cells through attachment of radionuclides to antibodies while limiting negative effects of off-target irradiation. This, however, requires effective facile methods for attachment of therapeutic radionuclides onto antibodies. Herein, the authors report their efforts in evaluating N-succinimidyl S-acetylthioacetate (SATA), a commercially available reagent, for use as a bifunctional chelating agent (BCA) to attach 188 Rhenium (188 Re) onto h8C3, a humanized IgG antibody that can effectively target extracellular melanin present in malignant melanoma...

Secreted inflammatory cytokines are considered as critical mediators in the tumor microenvironment. Cancer cells play a significant role in the differentiation of effector T cells to exhausted T cells through mediator production. Effector T cells that undergo tumor microenvironment become terminally differentiated into exhausted T cells. These changes create an opportunity for tumorigenesis and invasion of cancer cells. Despite having some characteristics of effector T cells, the exhausted T cells lose their antitumor properties...

The long noncoding RNA (LncRNA) SNHG7 (small nuclear RNA host gene 7) is a novel LncRNA and functions as an oncogene to promote tumor proliferation and inhibits apoptosis in many cancers. However, the role of SNHG7 in osteosarcoma (OS) remains to be further investigated. In this study, OS tissues and corresponding relative normal tissues (n = 30) were collected to determine the expression of SNHG7 in OS. The results indicated that high SNHG7 level in OS correlated with high Enneking stage, distant metastasis, and short overall survival time of OS patients...

Recently, the direct intratumoral (i.t.) injection of anticancer agents has been investigated. A newly synthesized Antineoplaston A10 analog 3-(4-methoxybenzoylamino)-2,6-piperidinedione (MPD) showed an antitumor activity in human breast cancer cell line. Unfortunately, MPD suffered from poor water solubility. Pseudoternary phase diagram of oil (isopropyl myristate), surfactant (Tween 80), cosurfactant (ethanol), and water was plotted. MPD microemulsion (MPDME) was developed and characterized for particle size (PS), polydispersity index (PDI), zeta potential (ZP), and morphology (transmission electron microscopy)...

The α-emitting radionuclide actinium-225 possesses nuclear properties that are highly promising for use in targeted α therapy (TAT), a therapeutic strategy that employs α particle emissions to destroy tumors. A key factor, however, that may hinder the clinical use of actinium-225 is the poor understanding of its coordination chemistry, which creates challenges for the development of suitable chelation strategies for this ion. In this article, we provide an overview of the known chemistry of actinium and a summary of the chelating agents that have been explored for use in actinium-225-based TAT...

Refinement of treatment regimens enlisting targeted α-radiation therapy (TAT) is an ongoing effort. Among the variables to consider are the target molecule, radionuclide, dosage, and administration route. The panitumumab F(ab')2 fragment targeting epidermal growth factor receptor tolerated modification with the TCMC chelate as well as radiolabeling with 203 Pb or 212 Pb. Good specific activity was attained when the immunoconjugate was labeled with 212 Pb (9.6 ± 1.4 mCi/mg). Targeting of LS-174T tumor xenografts with the 203 Pb-panitumumab F(ab')2 demonstrated comparable amounts of uptake to the similarly radiolabeled panitumumab IgG...

MiR-30d-5p, a member of the microRNA family, was recently reported to regulate androgen receptor signaling in prostate cancer (PCa). Ecto-5'-nucleotidase (NT5E/CD73) is a pivotal regulator of tumor migration and has angiogenetic properties. However, the undiscovered function of miR-30d-5p and whether it targeted NT5E in PCa remain uncertain. In this study, the authors observed miR-30d-5p was significantly downregulated in PCa tissues and cell lines compared with the adjacent normal tissues and normal prostate cells, respectively...
