KCMF1 regulates autophagy and ion channels' function in renal cell carcinoma: a future therapeutic target.
Article in Journal of cancer research and clinical oncology, 2023. 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
introductionIn RCC, systematic procedures such as surgery, chemo-radiation therapy, and application of target-based inhibitors increase the risk of several comorbidities such as chronic kidney disease, hemorrhage, and cardiac arrest that may increase the mortality rate. Even though immune-based checkpoint inhibitor therapies have an overall good response rate, it is restricted to only 30-40% of patients. Hence, an in-depth study of tumor pathophysiology in RCC is needed to identify the new therapeutic target. In RCC, persisted hypoxia is an essential phenomenon for tumor growth and progression. KCMF1 is a newly identified ubiquitin ligase whose domain interacts with destabilized proteins and reprogrammed the ubiquitin coding for lysosome-mediated degradation and autophagy under hypoxic conditions/oxidative stress and maintaining cellular homeostasis. But in RCC, the functional role of KCMF1 remains undefined to date.
methodWe determined KCMF1 and its associated proteins RAD6 and UBR4 expression and their co-localization using confocal microscopy in tumor and non-tumor tissues samples. Further, immunofluorescence staining was performed to determine autophagy (LC3B, p62), hypoxia-inducible factor (HIF-1A) and ion channel markers (Kv1.3, KCNN4) in RCC patients (n-10). Inductively coupled plasma mass spectrophotometry (ICPMS) was performed to estimate the concentration of potassium (K RESULT AND
conclusionWe observed a discrepancy in the formation of ubiquitin ligase, autophagosome via KCMF1, and ionic concentration in tumor cells, which might be one of the possible factors for cancer evolution. KCMF1-associated ubiquitin ligase system could be considered as a novel therapeutic target for RCC in the future.
