Background/aims: Tumor markers (TM) play an important role in the management of colorectal cancer (CRC). This study evaluates the predictive and prognostic value of preoperative serum carbohydrate antigen 242 (CA242) in CRC.
Methodology: Preoperative serum CA242 level was detected by C12 protein-chip diagnostic system in 185 CRC patients, and the predictive value of CA242 in stage, lymph node metastasis and tumor invasion depth was assessed. The prognostic value of CA242 for 5-year overall survival (OS) was analyzed.
Results: CA242 positive rate elevated with stage advancing, lymph node metastasis and tumor invasion depth, the differences between stage III+IV and stage I+II, between positive lymph node and negative lymph node, between T3+T4 and T1+T2, reached statistical significance (all p<0.05). Receiver operating characteristic analysis demonstrated that the area under the curve of CA242 in stage, lymph node metastasis and tumor invasion depth were 0.677, 0.631 and 0.744, respectively. Patients with higher CA242 had worse 5-year OS compared to those with normal CA242 (p=0.0002). Multivariate analysis showed stage (p=0.000) and preoperative serum CA242 (p=0.026) as independent prognostic factors for 5-year OS of CRC patients.
Conclusions: The preoperative serum CA242 can predict stage, lymph node metastasis and tumor invasion depth, and can be used as an independent prognostic factor for OS of CRC.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been detected in multiple animal species, including white-tailed deer (WTD), raising concerns about zoonotic transmission, particularly in environments with frequent human interactions. To understand how human exposure influences SARS-CoV-2 infection in WTD, we compared infection and exposure prevalence between farmed and free-ranging deer populations in Florida. We also examined the timing and viral variants in WTD relative to those in Florida's human population.

Robust CD8 T cell responses are critical for the control of HIV infection in both adults and children. Our understanding of the mechanisms driving these responses is based largely on studies of cells circulating in peripheral blood in adults, but the regulation of CD8 T cell responses in tissue sites is poorly understood, particularly in pediatric infections. DNA methylation is an epigenetic modification that regulates gene transcription.

Background/objectives: The extracellular calcium-sensing receptor (CaSR) is a multifunctional receptor proposed as a possible drug target for inflammatory bowel disease. We showed previously that CaSR inhibition with NPS 2143, a negative allosteric modulator of the CaSR, somewhat ameliorated the symptoms of chemically induced severe colitis in mice. However, it was unclear whether the potential of CaSR inhibition to reduce colitis may have been overshadowed by the severity of the induced inflammation in our previous study.

Background/objective: Ultraviolet (UV) B radiation leads to DNA damage by generating cyclobutane pyrimidine dimers (CPDs). UVB-induced CPDs can also result in immune suppression, which is a major risk factor for non-melanoma skin cancer (NMSC). UVB-induced CPDs are repaired by nucleotide repair mechanisms (NER) mediated by xeroderma pigmentosum complementation group A (XPA).

Disease monitoring informs the opportunities for intervention by natural resource agencies tasked with managing chronic wasting disease (CWD) in wild cervids. However, allocating funds toward testing can reduce those available for education, outreach, and disease reduction. Implementation of more efficient testing strategies can help meet both an expanding need by resource managers and a burgeoning demand from the hunting public in North America.
