The aim of this paper was to study the genetic background of the hyperfilamentous biofilm development in vitro in C. albicans isolated from the oral cavity of a lung cancer patient. Analyzed C. albicans isolates (CA1, CA2, CA3) were chosen based on their different structures of mature biofilm. The CA3 isolate possessing hyperfilamentation properties and forming high biofilm was compared with CA1 and CA2 isolates exhibiting low or average biofilm-forming ability, respectively. The detailed biofilm organization was studied with the use of confocal scanning laser microscopy. The whole transcriptome analysis was conducted during three stages of biofilm development (24 h, 48 h, 72 h). In contrast to CA1 and\/or CA2 isolate, the CA3 isolate was characterized by a significant upregulation of genes encoding for cell wall proteins (HWP1, PGA13, PGA44, ALS3) and candidalysin (ECE1), as well as being involved in iron metabolism (FRE1, ALS3), sulfur metabolism (HAL21), the degradation of aromatic compounds (HQD2), and membrane transport (DIP5, PHO89, TNA1). In contrast, some genes (SCW11, FGR41, RBE1) in the CA3 were downregulated. We also observed the overexpression of a few genes over time\u2014mainly FRE1, ATX1, CSA2 involved in iron metabolism. This is the first insight into the potential function of multiple genes in the hyperfilamentous biofilm formation in C. albicans, primarily isolated from host tissue, which may have an important clinical impact on cancer patients. Moreover, the presented data can lay the foundation for further research on novel pathogen-specific targets for antifungal drugs.<\/jats:p>","DOI":"10.3390\/ijms24010368","type":"journal-article","created":{"date-parts":[[2022,12,27]],"date-time":"2022-12-27T04:42:47Z","timestamp":1672116167000},"page":"368","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The Landscape of Gene Expression during Hyperfilamentous Biofilm Development in Oral Candida albicans Isolated from a Lung Cancer Patient"],"prefix":"10.3390","volume":"24","author":[{"given":"Beata","family":"Chudzik-Rz\u0105d","sequence":"first","affiliation":[{"name":"Department of Pharmaceutical Microbiology, Medical University of Lublin, 1 Chod\u017aki St., 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2254-2009","authenticated-orcid":false,"given":"Daniel","family":"Zalewski","sequence":"additional","affiliation":[{"name":"Department of Biology and Genetics, Medical University of Lublin, 4a Chod\u017aki St., 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martyna","family":"Kasela","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Microbiology, Medical University of Lublin, 1 Chod\u017aki St., 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6593-8484","authenticated-orcid":false,"given":"Rafa\u0142","family":"Sawicki","sequence":"additional","affiliation":[{"name":"Department of Biochemistry and Biotechnology, Medical University of Lublin, 1 Chod\u017aki St., 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jolanta","family":"Szyma\u0144ska","sequence":"additional","affiliation":[{"name":"Department of Comprehensive Paediatric and Adult Dentistry, Medical University of Lublin, 6 Chod\u017aki St., 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Bogucka-Kocka","sequence":"additional","affiliation":[{"name":"Department of Biology and Genetics, Medical University of Lublin, 4a Chod\u017aki St., 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1503-7634","authenticated-orcid":false,"given":"Anna","family":"Malm","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Microbiology, Medical University of Lublin, 1 Chod\u017aki St., 20-093 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"638609","DOI":"10.3389\/fmicb.2021.638609","article-title":"Mechanistic understanding of Candida albicans biofilm formation and approaches for its inhibition","volume":"12","author":"Atriwal","year":"2021","journal-title":"Front.
