For the TCGA data sets, the original samples are unavailable for further studies; however, hematoxylin and eosin (H&E) digital slides have been publicly released. While it is not possible to distinguish T cells and B cells by H&E, neutrophils are morphologically distinctive and their abundance can be estimated. Occasional dendritic cells and macrophages can be identified by H&E but their true abundance is difficult to estimate in the absence of immunohistochemical stains. Slides were reviewed via digital images viewed with the Cancer Digital Slide Archive (http://cancer.digitalslidearchive.net). We chose BLCA because it has a large sample size (n = 404), does not have excessive necrosis, and has sufficient neutrophil counts and sample variety to allow for validation by histological evaluation. The pathologist reviewing the slides was blinded to the in silico neutrophil predictions. Samples were stratified into three groups (high, medium, low) with levels of neutrophils relative to the entire collection of samples.

The strains of C. albicans used in this study are listed in supplemental Table S2. For routine growth, modified Lee's medium without methionine was used [31] (link), unless stated otherwise. For repression of MET3 promoter-controlled gene expression, 2.5 mM methionine and 2.5 mM cysteine were added to the medium. For GlcNAc induction, the carbon source glucose was replaced with GlcNAc (1.25% w/v) in nutrient medium. Here, agar containing Lee's medium, in which glucose was the carbon source, was referred to as glucose agar and Lee's medium containing GlcNAc as a carbon source was referred to as GlcNAc agar. Agar cultures were grown at a density of 80–120 colonies per 85 mm plate. Phloxine B was added to nutrient agar for opaque colony staining [46] (link).

Table lists the yeast strains and Table the plasmids used. Sherman 1991 and Ausubel et al. 1996 describe the methods used for growth, maintenance, and genetic manipulation of yeast, and Gietz and Schiestl 1995 describe the method used to transform yeast.
Temperature-sensitive myo2 strains were generated by replacing the 3′ region of the endogenous genomic MYO2 gene with mutagenized plasmid DNA. To construct a plasmid capable of integrating 3′ to MYO2, pJP10-2B (YCp50 containing MYO2) ( Johnston et al. 1991) was cut with SpeI and the resulting fragments circularized using T4 DNA ligase. The ligated DNA served as template for five cycles of amplification by PCR using Taq DNA polymerase and the oligonucleotide primers GATAATGAAATCGATATTATGGAAGA and CGGGATCCATTATCATACTATACTATTGACAAATACTTC. The ClaI-BamHI segment of the 1.7-kb product was inserted into pRS303 ( Sikorski and Hieter 1989). Destruction of the pRS303 SpeI site by cutting with SpeI (partial digest) and XbaI and religation produced the plasmid pRS303MYO2, containing the 201-bp ClaI-SpeI fragment of the MYO2 3′ untranslated region, followed by the 1,587-bp segment of MYO2 from the SpeI site at +3271 on, fused to the sequence GCACTAGA and the NotI site of pRS303.
pRS303MYO2 served as a template for PCR-based mutagenesis ( Cadwell and Joyce 1992), modified to reduce the mutation frequency. The reaction mix (1 mM dCTP, 1 mM dTTP, 0.2 mM dATP, 0.2 mM dGTP, 40 ng pRS303MYO2 cut with PvuII, 7 mM MgCl2, 0.5 mM primers, 50 mM KCl, 10 mM Tris-HCl, pH 8.3, 10 mg BSA, and 0.05% Tween 20; and after the mix had warmed up to 80°C, 0.3 mM MnCl2 and 5u Taq DNA polymerase) was subjected to six cycles of amplification and the EcoRI-NotI fragment of the PCR product was subcloned into the corresponding region of pRS303MYO2 to make libraries of mutagenized MYO2. When cut with SpeI and transformed into yeast, the library plasmids insert pRS303 (containing HIS3) into the ClaI site of the MYO2 3′ untranslated region, and replace the EcoRI-ClaI region of MYO2 with mutagenized sequence encoding amino acid residues 1119 to the COOH terminus.
Roughly 500 transformants at 30°C were replica-plated to 14 and 37°C to detect conditional-lethal mutants. Phloxine B included in plates at 10 mg/liter allowed easier identification of growth-arrested yeast ( Horn and Wilkie 1966). Because dead cells absorb this red dye, red marks correspond to the positions of temperature-sensitive colonies. Genomic DNA from each of the temperature sensitives was cut with SpeI and circularized to reconstitute versions of pRS303MYO2 containing mutations. Transformation of these plasmids relinearized with SpeI into the yeast strain PSY316 yielded the temperature-sensitive strains ABY532, 533, 534, 536, 537, 538, and 530. The temperature sensitivity could be complemented by transformation with pJP10-2B (MYO2 on a low copy number plasmid) or by mating with a MYO2 strain, but could not be complemented by mating with JP7B, a myo2-66 strain. ABY531, an isogenic MYO2 strain, was made by transformation of PSY316 with pRS303MYO2. An analogous series of plasmids made from pRS306 (containing URA3) allowed the construction of yeast strains containing myo2 alleles tagged with URA3. To make an isogenic myo2-66 strain, genomic DNA from JP7B transformed with pRS303MYO2 was cut with NcoI and religated, resulting in an integrating plasmid analogous to pRS303MYO2, but containing the full-length myo2-66 gene instead of the MYO2 fragment. This plasmid was cut with NcoI and transformed into PSY316 to construct ABY535. Diploid versions of these strains were made by transiently transforming with YCp50HO, a plasmid bearing HO ( Herskowitz and Jensen 1991).

White-opaque switching and mating assays were performed as previously described [36] (link). The cells were incubated in air or in 5% CO2 for 4 to 10 days as indicated in the main text. We examined 350 to 500 colonies for each strain. More were tested for nonswitchable strains or on nonconducive media. To verify the colony phenotype, several randomly selected colonies were examined for the cellular morphology. The dye phloxine B, which exclusively stains opaque colonies red, was added to the media. Scanning electron microscopy (SEM) assay was described as we described previously [22] (link). To observe the mating response, 106 cells of each of the two mating strains indicated in the text were mixed and spotted onto Lee's GlcNAc agar and incubated at 25°C for 4 days. At least 1×107 cells of each mating patch were examined with a light microscopy. Quantitative mating assay was performed as previously described with slight modifications [10] (link). Briefly, the mating experiments were performed on Lee's GlcNAc medium at 25°C. The experimental opaque cell samples were collected from Lee's GlcNAc medium plates. To test the mating ability of the MTLa/α strain (SZ306u), 1×106 of MTLa/a (or MTLα/α) cells and 1×106 of MTLa/α cells were mixed and cultured on Lee's GlcNAc medium plates for 48 hours. The mating mixtures were resuspended, diluted, and plated onto three types of selectable plates (without uridine, or arginine, or both) for prototrophic growth. Mating efficiencies were calculated as previously described [14] (link).
The library of transcription factor mutants contains the TF mutants generated by the Johnson lab [37] (link) and strains collected from Candida community [36] (link). Cells of each mutant were plated onto Lee's GlcNAc plates and incubated at 25°C for 7 to 10 days. Opaque colonies were replated and tested for the MTL genotype with PCR.

The photocatalytic activity of M-HW was evaluated through the photocatalytic degradation of the organic pollutants. Precisely, 1 mg of M-HW composites (photocatalyst) was added to 40 mL of MO (20 mg/L, target dye). The mixture was stirred continuously in the dark for 30 min to obtain a homogenized mixture and achieve adsorption–desorption equilibrium. Then, the mixture was transferred to the photocatalytic reaction system and irradiated under light at a specific time, and aliquots of 4 mL of the solution were collected in 7 mL Eppendorf (Ep) tubes every 20 min, and the supernatant was removed twice using high-speed centrifugation at 9500 rpm for 10 min. The absorbance value of MO at the maximum absorption wavelength (464 nm) was measured using a visible spectrophotometer (Shanghai Prism Technology 722SP). Different target dyes, such as rhodamine B (1 × 10−5 M, λmax = 554 nm) and eosin B (5 × 10−5 M, λmax = 518 nm), were changed in the same condition to record the maximum absorption value. The photocatalytic activities of M-HW on different dyes were studied using the photocatalytic degradation curve.
The photocatalytic degradation curve of organic dyes can be fitted using the first-order kinetic Equation (1) as follows: InC0C=kt
where C0 (mg/mL) and C (mg/mL) represent the initial organic dye concentration and the dye concentration after irradiation, respectively; k represents the apparent rate constants, and t represents the reaction time (min) [44 (link)]. Thus, k was used to evaluate the photocatalytic activity in this work.
