Although human papillomavirus (HPV) infection is necessary for cervical squamous intraepithelial lesion (SIL/CIN) and cancer to develop, exposure to HPV is not predictive of which women will develop SIL/CIN and cancer. This study examines mRNA expression of several potential biomarkers in exfoliated cervical cells collected from college-aged women.
Freshman female students were recruited into the Carolina Women's Care Study, which was designed to prospectively evaluate factors that contribute to persistent HPV infections. One component of this study was to extract mRNA from exfoliated cervical cells. In this study, mRNA expression of Frizzled (FZD), growth differentiating factor 15, interleukin 1 beta (IL1β), and N-cadherin was assessed through real-time polymerase chain reaction. Statistical analysis was performed with a Student t test; all results were standardized with glyceraldehyde 3-phosphate dehydrogenase.
Fifty samples were selected that reflected the demographics of the Carolina Women's Care Study participants. IL1β mRNA expression was 9.4-fold higher in cervical cells from women with abnormal Pap tests (p = .0018); low-grade squamous intraepithelial lesion had 12.7-fold higher expression than negatives (p = .0011). The FZD mRNA expression was 5.7-fold higher in CIN 2 as compared with CIN 1 (p = .0041) and 8.5-fold higher compared with cytology/pathology negative (p = .0014). Other differences in mRNA expression showed trends but not reaching statistical significance for each condition.
It seems that several biomarkers involved in the cytokine/inflammatory pathway (IL1β), cell adhesion pathway (N-cadherin), growth factor (growth differentiating factor 15), and Wingless (WNT) signaling pathway (FZD) may be potential biomarkers in conjunction with the Pap test and HPV that help predict which women are at highest risk for developing CIN 3 and cervical cancer.
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 20 November 2015.
All research outputs
#17,151,188
of 26,184,649 outputs
Outputs from Journal of Lower Genital Tract Disease
#337
of 626 outputs
Outputs of similar age
#232,779
of 403,249 outputs
Outputs of similar age from Journal of Lower Genital Tract Disease
#9
of 19 outputs
Altmetric has tracked 26,184,649 research outputs across all sources so far. This one is in the 33rd percentile – i.e., 33% of other outputs scored the same or lower than it.
So far Altmetric has tracked 626 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.7. This one is in the 43rd percentile – i.e., 43% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 403,249 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 41st percentile – i.e., 41% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 19 others from the same source and published within six weeks on either side of this one. This one is in the 42nd percentile – i.e., 42% of its contemporaries scored the same or lower than it.
