Despite an abundance of data describing expression of genes in the Candida albicans ALS (agglutinin-like sequence) gene family, little is known about the production of Als proteins on individual cells, their spatial localization or stability. Als proteins are most commonly discussed with respect to function in adhesion of C. albicans to host and abiotic surfaces. Development of a mAb specific f...

BACKGROUND Biofilms are surface-associated microbial communities with significant environmental and medical impact. Here, we focus on an adherence mechanism that permits biofilm formation by Candida albicans, the major invasive fungal pathogen of humans. RESULTS The Als surface-protein family has been implicated in biofilm formation, and we show that Als1 and Als3 have critical but redundant ...

The ALS (agglutinin-like sequence) gene family of Candida albicans encodes eight cell-surface glycoproteins, some of which are involved in adherence to host surfaces. A mutational analysis of each ALS gene is currently being performed to deduce the functions of the encoded proteins and to better understand the role of these proteins in C. albicans biology and pathogenesis. This paper describes ...

Candida albicans PALS-green fluorescent protein (GFP) reporter strains were inoculated into mice in a disseminated candidiasis model, and GFP production was monitored by immunohistochemistry and reverse transcription-PCR (RT-PCR). GFP production from the ALS1 and ALS3 promoters was detected immunohistochemically. ALS1, ALS2, ALS3, ALS4, and ALS9 transcription was detected by RT-PCR, further ide...

TAR DNA binding protein 43 (TDP-43) has been considered a signature protein in frontotemporal dementia and amyotrophic lateral sclerosis (ALS), but not in ALS associated with the superoxide dismutase 1 (SOD1) gene mutations (ALS1). To clarify how TDP may be involved in ALS pathogenesis, clinical and pathological features in cases of sporadic ALS ([SALS] n = 18) and ALS1 (n = 6) were analyzed. I...

BACKGROUND Sulfonylurea (SU) herbicides are effective because they inhibit acetolactate synthase (ALS), a key enzyme in branched-chain amino acid synthesis required for plant growth. A soybean line known as W4-4 was developed through rounds of seed mutagenesis and was demonstrated to have a high degree of ALS-based resistance to both post-emergence and pre-emergence applications of a variety of...

Sulfonylurea (SU) herbicides registered for use in other crops Australia may leave residues the soil interrupting rotations involving soybean. However, two unlinked genes (ALS1 and ALS2) confer SU tolerance Here, we report experiments that explored effectiveness of these ALS Australian soybean germplasm. The first assessed to halosulfuron-methyl or metsulfuron-methyl lines with either zero gene...

The fungal pathogen Candida albicans has the ability to grow as a biofilm on synthetic materials. This presents a significant problem in the clinical situation when the organism grows as a biofilm on medical devices resulting in infections which are resistant to antifungal agents. Determining the extent to which certain genes are involved in biofilm formation is an important aspect for the deve...

candida albicans is an opportunistic fungi that is able to thrive in many host niches, including the skin, mucosal, surfaces, the blood stream and internal organs. agglutinin-like sequence (als) genes which could play a role in forming biofilms, adherence to host surfaces as a virulence factor and antifungal drug resistant. the purpose of the present study was to evaluate the presence als1 and ...
