Impact of IFNalpha2b upon pSTAT3 and the MEK/ERK MAPK pathway in melanoma.
Trial report in Cancer immunology, immunotherapy : CII, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeHigh-dose IFNalpha2b (HDI) was established as the first effective adjuvant therapy for patients with high-risk resected melanoma more than a decade ago, but its fundamental molecular mechanism of action remains unclear. STAT3 and the mitogen activated protein kinases (MAPKs), especially ERK (extracellular signal-regulating kinase) and MEK (MAPK/ERK kinase), play roles in melanoma progression and host immunity. We have therefore evaluated STAT3 and MEK/ERK MAP kinases in patients with regional lymph node metastasis (stage IIIB) of melanoma in the context of a prospective neoadjuvant trial of HDI (UPCI 00-008). PATIENTS AND
methodsIn the context of this trial, HDI was administered daily for 20 doses following diagnostic biopsy, and prior to definitive surgery. Immunohistochemistry for pSTAT3, phospho-MEK1/2, phospho-ERK1/2, and EGFR was performed on paired fixed (nine patients) biopsies.
resultsHDI was found to down-regulate pSTAT3 (P = 0.008) and phospho-MEK1/2 (P = 0.008) levels significantly in tumor cells. Phospho-ERK1/2 was down-regulated by HDI in tumor cells (P = 0.015), but not in lymphoid cells. HDI down-regulated EGFR (P = 0.013), but pSTAT3 activation appeared not to be associated with EGFR expression and the MEK/ERK MAPK pathway.
conclusionWe conclude that HDI regulates MAPK signaling differentially in melanoma tumor cells and host lymphoid cells in vivo. STAT3 activation is independent of the EGFR/MEK/ERK signaling pathway.
