“…Interestingly, the expression of both LNC2 and MMP9 genes was increased in 16 tumor types, demonstrating Frontiers in Cell and Developmental Biology frontiersin.org their involvement in tumor development. This result was consistent with those reported in the literature for several tumors, including BLCA (Ricci et al, 2015;Candido et al, 2016b), CESC (Li et al, 2012), CHOL (Leelawat et al, 2011;Nair et al, 2018;, ESCA (Zhang et al, 2007), HNSC (Ruokolainen et al, 2005;Hiromoto et al, 2011;Stanciu et al, 2016;Verma et al, 2017), KIRP (Cho et al, 2003;Zhang et al, 2015), LIHC (Chen et al, 2012;Abdelsameea et al, 2020), LUAD (Ruiz-Morales et al, 2015), OV (Cho and Kim, 2009;Gupta et al, 2022); PAAD (Kaur et al, 2013), STAD (Du et al, 2011), UCEC (Cymbaluk-Płoska et al, 2017), COAD (Yang et al, 2014;Ozemir et al, 2016;Liang and Chang, 2018), LUSC (Lee et al, 2015), PRAD (Ma et al, 2017;Muşlu et al, 2017;Ulusoy et al, 2021), READ (Zhang et al, 2009;Annaházi et al, 2016), and THCA (Barresi et al, 2012;Liu et al, 2019;Xu et al, 2019). Despite many authors reporting that LNC2 and MMP9 were widely associated with worse prognosis in several tumors, our in silico analysis revealed that the OS and PFI were simultaneously negatively affected by both genes only in KIRC patients.…”
