However, the values that lie outside the overall pattern of a distribution, the outliers, are frequently excluded in traditional analytical methods as they are considered to be \u2018some sort of problem.\u2019 Such outliers may have a biologic role in the disease group. Thus, this study explored new biomarker using outlier analysis, and verified the suitability of therapeutic potential of two genes (TM4SF4 and LRRK2).Materials and MethodsModified Tukey\u2019s fences outlier analysis was carried out to identify new biomarkers using the public gene expression datasets. And we verified the presence of the selected biomarkers in other clinical samples via customized gene expression panels and tissue microarrays. Moreover, a siRNA-based knockdown test was performed to evaluate the impact of the biomarkers on oncogenic phenotypes.Results&lt;i&gt;TM4SF4&lt;\/i&gt; in lung cancer and &lt;i&gt;LRRK2&lt;\/i&gt; in breast cancer were chosen as candidates among the genes derived from the analysis. TM4SF4 and LRRK2 were overexpressed in the small number of samples with lung cancer (4.20%) and breast cancer (2.42%), respectively. Knockdown of &lt;i&gt;TM4SF4&lt;\/i&gt; and &lt;i&gt;LRRK2&lt;\/i&gt; suppressed the growth of lung and breast cancer cell lines. The LRRK2 overexpressing cell lines were more sensitive to LRRK2-IN-1 than the LRRK2 under-expressing cell linesConclusionOur modified outlier-based analysis method has proved to rescue biomarkers previously missed or unnoticed by traditional analysis showing TM4SF4 and LRRK2 are novel target candidates for lung and breast cancer, respectively.<\/jats:p>","DOI":"10.4143\/crt.2020.434","type":"journal-article","created":{"date-parts":[[2020,9,16]],"date-time":"2020-09-16T05:38:47Z","timestamp":1600234727000},"page":"9-24","update-policy":"https:\/\/doi.org\/10.4143\/crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["TM4SF4
