Abstract:

Objective:To investigate the gene expression and polymorphisms of vitamin D receptor (VDR) in nasopharyngeal carcinoma. Method:The expression of VDR mRNA was detected by fluorescent quantitative PCR in PBMC from 48 patients with nasopharyngeal carcinoma and 48 controls. The FokI and ApaI loci of all subjects were detected by TaqMan-MGB fluorescent probe PCR. Result:The VDR mRNA △Ct value was 9.32±0.91 and 7.31±1.04 in nasopharyngeal carcinoma patients and controls, respectively. Using multivariate Logistic regression analysis, the results showed that the distribution of FokI point Ff genotype in the case group was significantly higher than that in the control group (adjusted OR=1.97, 95%CI=1.33-2.91). No difference was found between the control group and the patient group at ApaI loci. Further haplotype analysis was used to find that compared with fa haplotypes, the distribution of FokI Ff genotype in the case group was significantly higher than that in the healthy control group (adjusted OR=0.65, 95%CI=0.48-0.87). There were significant differences in the gene expression level of VDR among the patients with the different genotypes of FokI loci (F=194.5, P<0.01). Conclusion:Genetic variants of the VDR gene are closely associated with nasopharyngeal carcinoma.

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Vitamins

Vitamins

Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

Animal Mitochondrial Genetics

Animal Mitochondrial Genetics

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Single Nucleotide Polymorphisms-SNPs

Single Nucleotide Polymorphisms-SNPs

A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Associative Learning

Associative Learning

Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Association Areas of the Cortex

Association Areas of the Cortex

Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
