Conjugation of Cetuximab - Puromycin and Its Target-Specific Effect on Triple Negative Breast Cancer Cell Lines.
Article in Asian Pacific journal of cancer prevention : APJCP, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Cancer is life-threatening disease and being global health problems. Chemotherapy is one of the most used therapy for cancer since many years ago. Chemotherapy is also toxic for normal cell, not specific to the target cells. Consequently, chemotherapy has various side effects. Monoclonal antibody (MAb) has been developed for specific therapy which only has killing effect in cancer cells, but the survival rate of most MAbs around 20%. Therefore, in clinical practice, MAbs administration should combine with chemotherapeutic agents. For effectiveness of therapy and to minimalize adverse effects, anticancer agent with selective cytotoxic effect on target cells is needed, the immunotoxin.
objectiveThis study introduces a novel approach to conjugate monoclonal antibody (Cetuximab) and toxin (Puromycin), in order to selectively inhibit proliferation of triple negative breast cancer (TNBC) and to enhance the efficacy of MAb in target cells killing.
methodsCetuximab was conjugated with Puromycin using a linker, i.e SATP (Succinimidyl-acetylthiopropionate) and tested on triple negative breast cancer cell lines (MDA-MB-231) which expressed EGFR (epidermal growth factor receptor). Cetuximab is MAb which targets EGFR. MCF-7 was used as control cells since it has low or no EGFR expression. Cell counting were conducted as viability assay at 24 hours, 48 hours, and 72 hours after treatment.
resultsThe results showed significant reduction of live cells number in Conjugate 20 µg/mL cultured in MDA-MB-231 compared to MCF-7 after 24 hours, 48 hours, and 72 hours incubation. In all time period of incubation, significant reduction of MDA-MB-231 live cells number was also observed in Conjugate 20 µg/mL compared to Cetuximab 20 µg/mL.
conclusionSynthesized conjugate showed its target-specific effect in TNBC and improved the efficacy of Cetuximab on TNBC. In the future, this conjugate can be a potential anticancer therapy in treating triple-negative breast cancer.
