A Peroxisomal Lon Protease and Peroxisome Degradation by Autophagy Play Key Roles in Vitality of Hansenula polymorpha Cells [PDF]

open access: yes, 2007
In eukaryote cells various mechanisms exist that are responsible for the removal of non-functional proteins. Here we show that in the yeast Hansenula polymorpha (H.

Rat Porphobilinogen Deaminase Gene: A Pseudogene-Free Internal Standard for Laser-Assisted Cell Picking

open access: yesBioTechniques, 1999
Analysis of gene expression and its transcriptional regulation requires a reliable access to target mRNA. However, mRNA extractions from homogenized tissue are limited because only average data are obtained, and cell-specific expression may not be ...

Further understanding human disease genes by comparing with housekeeping genes and other genes [PDF]

open access: yesBMC Genomics, 2006
Abstract Background Several studies have compared various features of heritable disease genes with other so called non-disease genes, but they have yielded some conflicting results. A potential problem in those studies is that the non-disease genes contained a large number of essential genes – genes which are ...

Selection of candidate housekeeping controls in tomato plants using EST data

open access: yesBioTechniques, 2003
Because the expression levels of housekeeping genes are relatively constant in most tissues, they are often useful controls when quantifying gene expression.

Phylogeny of Flavobacteria Group Isolated from Freshwater Using Multilocus Sequencing Analysis [PDF]

open access: yesGenomics & Informatics, 2013
Sequence analysis of the 16S rRNA gene has been widely used for the classification of microorganisms. However, we have been unable to clearly identify five Flavobacterium species isolated from a freshwater by using the gene as a single marker, because ...

Identification of Appropriate Housekeeping Genes for Gene Expression Analysis in Long-term Hypoxia-treated Kidney Cells

open access: yesAdvanced Biomedical Research, 2017
Background: Selection of stably expressing housekeeping genes (HKGs) is a crucial step in gene expression analysis. However, there are no universal HKGs for all experiments, and they should be determined by each biologic condition.

Phylogenetic analysis of Leuconostoc and Lactobacillus species isolated from sugarcane processing streams

open access: yesMicrobiologyOpen, 2020
High levels of gums such as dextran, produced by Leuconostoc and Lactobacillus spp., have a severe impact on factory throughput and sugar quality.

Using ribosomal protein genes as reference: a tale of caution. [PDF]

open access: yesPLoS ONE, 2008
BACKGROUND: Housekeeping genes are needed in every tissue as their expression is required for survival, integrity or duplication of every cell. Housekeeping genes commonly have been used as reference genes to normalize gene expression data, the ...
