This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Population-based studies showed that COVID-19 infection causes higher death rate in cancer patients. However, the molecular mechanism of COVID-19 with cancer is still largely unknown. Here we analyzed the Leucine Zipper Transcription Factor-Like Protein 1 (LZTFL1) which is the most significant gene associated with COVID-19. First, we explored the potential oncogenic roles of LZTFL1 through transcriptome data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) database. LZTFL1 is significantly low expressed in 11 of 34 kinds of cancers we analyzed. Consistent with the mRNA expression data, the protein expression of LZTFL1 in lung adenocarcinoma (LUAD), clear cell renal cell carcinoma (ccRCC), Uterine corpus endometrial carcinoma (UCEC), and ovarian cancer (OV) patients are significantly decreased compared to healthy tissues. The survival analysis from the Kidney renal clear cell carcinoma (KIRC), Rectum adenocarcinoma (READ), and Uveal Melanoma (UVM), the LZTFL1 high expression group have a significantly higher survival rate compared to the low expression group. Taken together, LZTFL1 acts as a cancer suppressor gene for several cancers. Moreover, LZTFL1 expression was associated with the cancer-associated fibroblast infiltration in several tumors including Bladder Urothelial Carcinoma (BLCA), Breast invasive carcinoma (BRCA), Esophageal carcinoma (ESCA), Head and Neck squamous cell carcinoma (HNSC), Lung squamous cell carcinoma (LUSC), and Pancreatic adenocarcinoma (PAAD). Gene ontology analysis showed that cilium organization, positive regulation of establishment of protein localization to telomere and SRP-dependent cotranslational protein targeting to the membrane were involved in the function mechanisms related to LZTFL1. Our studies offer a relatively comprehensive understanding of the oncogenic roles of LZTFL1 across different kinds of tumors.
