Abstract
Chronic stress can accelerate biological aging, offering one mechanism through which stress may increase age-related disease risk. Chronic activation of the sympathoadrenal system increases cellular energy production, resulting in cell stress that can initiate cellular senescence, a permanent state of cell growth arrest. Our previous research linked psychosocial stress with increased expression of senescence marker p16INK4a; however, less is known about the role of protective psychosocial factors in biological aging. We examined relationship closeness (perceived interconnectedness with one's spouse) as a protective buffer of the effects of stress on expression of the p16INK4a-encoding gene (CDKN2A) and transcription control pathways activated under cell stress. Seventy parents (Mage=43.2) completed interview-based and questionnaire measures of psychosocial stress and relationship closeness. Blood samples assessed CDKN2A expression and inferred activity of a priori-selected transcription factors Nrf2 and heat shock factors (HSFs) via genome-wide transcriptome profiling. Random intercept models adjusting for age, sex, and ethnicity/race revealed that perceived stress was associated with elevated CDKN2A expression for parents with low but not high closeness. Secondary bioinformatics analyses linked the interaction of perceived stress and relationship closeness to Nrf2 and HSF-1 activity. Findings identify relationship closeness as a protective factor that may buffer the impact of stress on cellular stress and senescence pathways.

Abstract
Patients with end-stage renal disease (ESRD) display phenotypic features of premature biological aging, characterized by disproportionately high morbidity and mortality at a younger age. Nuclear factor erythroid 2-related factor 2 (Nrf2) activity, a master regulator of antioxidative responses, declines with age and is implicated in the pathogenesis of age-related disorders; however, little is known about the association between Nrf2 and premature biological aging in ESRD patients. In a cross-sectional pilot cohort of 34 ESRD patients receiving maintenance hemodialysis, we measured the expression of Nrf2 and cyclin-dependent kinase inhibitor 2A (CDKN2A, or p16INK4a, a biomarker of biological aging) genes in whole blood and examined the association of Nrf2 with CDKN2A expression, using Spearman's rank correlation and multivariable linear regression models with adjustment for potential confounders. There was a significant negative correlation between Nrf2 and CDKN2A expression (rho=-0.51, P=0.002); while no significant correlation was found between Nrf2 expression and chronological age (rho=-0.02, P=0.91). After multivariable adjustment, Nrf2 expression remained significantly and negatively associated with CDKN2A expression (β coefficient=-1.51, P=0.01), independent of chronological age, gender, race, and diabetes status. These findings suggest a potential contribution of Nrf2 dysfunction to the development of premature biological aging and its related morbidities in ESRD patients.

Abstract
BACKGROUND The surrogate immunohistochemical marker, p16INK4a, is used in clinical practice to determine the high-risk human papillomavirus (HPV) status of oropharyngeal squamous cell carcinomas (OPSCC). With a specificity of 83%, this will misclassify some patients compared with direct HPV testing. Patients who are p16INK4a-positive but HPV DNA-negative, or RNA-negative, may be unsuitable for treatment de-escalation aimed at reducing treatment-related side effects. We aimed to identify cost-effective serum markers to improve decision making for patients at risk of misclassification by p16INK4a alone. METHODS Serum proteins from pre-treatment samples of 36 patients with OPSCC were identified and quantified using label-free mass spectrometry-based proteomics. HPV-status was determined using p16INK4a/HPV DNA and E6/E7 mRNA. Serum protein expressions were compared between groups of patients according to HPV status, using the unpaired t-test with a Benjamini-Hochberg correction. ROC curves (AUC) were calculated with SPSS (v25). RESULTS Of 174 serum proteins identified, complement component C7 (C7), apolipoprotein F (ApoF) and galectin-3-Binding Protein (LGALS3BP) significantly differed between HPV-positive and -negative tumors (AUC ranging from 0.84-0.87). ApoF levels were more than twice as high in the E6/E7 mRNA HPV-positive group than HPV-negative. CONCLUSIONS Serum C7, ApoF and LGALS3BP levels discriminate between HPV-positive and HPV-negative OPSCC. Further studies are needed to validate these host immunity-related proteins as markers for HPV-associated OPSCC.

Abstract
Sedentary lifestyle and high visceral adiposity have elevated the risk of type 2 diabetes (T2DM) among Indians at younger age. In this study, we aimed to investigate the association of oxidative stress and chronic inflammatory mediators with ageing with special reference to the biological ageing marker cyclin-dependent kinase inhibitor 2A (CDKN2A) among middle-aged (31-50 years) Indian healthy and T2DM subjects. Malondialdehyde (MDA), oxidized LDL (oxLDL), interleukin-6 (IL-6), interleukin 1β (IL-1β), tumor necrosis factor α (TNF-α), monocyte chemoattractant protein-1 (MCP-1), and CDKN2A were measured in T2DM patients (n = 80) and controls (n = 80) aged 31-50 years, further grouped into G1: 31-40 years and G2: 41-50 years. IL-6, TNF-α, MCP-1, and CDKN2A showed a significant association with ageing among both T2DM patients and controls. But the strength of the association of MCP-1 and CKDN2A with ageing was significantly stronger in T2DM patients than the controls. All the oxidative stress and proinflammatory mediators showed nonsignificant associations with CDKN2A in the controls. However, IL-6, TNF-α, and MCP-1 showed a strong association with CDKN2A in T2DM patients. An increased risk of high levels of CDKN2A was found in G1 T2DM patients (OR: 3.484 (95% CI: 1.246-9.747) p = 0.017) and G2 T2DM patients (OR: 5.000 (95% CI: 1.914-13.061), p = 0.001) with reference to the respective control groups. Our study reveals that the middle-aged Indians with T2DM are at higher risk of biological ageing. The development of T2DM is more common among middle-aged Indians. T2DM may exacerbate the ageing process and may subsequently predispose Indians to various age-related complications at a much early age.

Abstract
INTRODUCTION Human papillomavirus (HPV) is a known prognostic indicator in oropharyngeal cancer. Not much is known about the prognostic role of HPV in Nasopharyngeal cancer (NPC). Here, we performed a systematic review and meta-analysis of the literature to investigate if HPV status was a prognostic factor for NPC. METHODS PubMed (via the web), Embase, Scopus, and the Cochrane Library were searched. A systematic review and meta-analysis was done to generate the pooled Hazard Ratios (HR) for Overall Survival (OS). RESULTS A total of 7 studies from 2014 to 2018, reporting data on 2646 patients (range 43-1328) were included in this meta-analysis. The pooled data showed that HPV/p16 status was not associated with OS in NPC with HR of 0.77 (95% CI: 0.55-1.09, p = 0.14). The test for heterogeneity showed little to no heterogeneity of results (I2 = 4%, p = 0.38). Subgroup analysis showed that in large sample sizes, HPV was significantly associated with survival. CONCLUSION Despite the finding in the pooled HR, we could not draw a definitive conclusion as to the prognostic significance of HPV in NPC. Recommendations for future research are given.

Abstract
BACKGROUND This meta-analysis was conducted to investigate the diagnostic performance of P16INK4a gene promoter methylation as a biomarker of non-small cell lung cancer (NSCLC). METHODS Two reviewers independently searched the Web of Science, PubMed, Cochrane, Embase, China National Knowledge Infrastructure, and Chinese Biomedical Literature databases. Publications relevant to P16INK4a gene promoter methylation in serum or bronchoalveolar fluid/sputum were screened and included in this meta-analysis. Pooled diagnostic sensitivity, specificity, and symmetric receiver operating characteristic curve were calculated. RESULTS Twenty-six publications with 1768 lung cancer cases and 1323 controls were included. The pooled sensitivity, specificity, positive and negative likelihood ratios, and diagnostic odds ratio were 0.46 (95% confidence interval [CI] 0.43-0.48), 0.90 (95% CI 0.88-0.91), 6.33 (95% CI 3.89-10.30), 0.57 (95% CI 0.50-0.65) and 10.72 (95% CI 6.94-16.56), respectively, for P16INK4a gene promoter methylation as a biomarker for the diagnosis of NSCLC. The area under the symmetric receiver operating characteristic curve was 0.75 with a standard error of 0.004. No publication bias was detected via line regression test (t = 0.95; P = 0.35) and Begg's funnel plot. CONCLUSION P16INK4a gene promoter methylation detection in serum or bronchoalveolar fluid/sputum may be a potential biomarker for NSCLC diagnosis; however, the sensitivity was relatively low, which is not suitable for NSCLC screening.

Abstract
Purpose Recently, p16 has been included in the TNM guideline for oropharyngeal carcinomas. The role of HPV and p16 in hypopharyngeal and laryngeal carcinomas has not yet been established sufficiently. Methods Hundred and thirty-four patients with hypopharyngeal and laryngeal carcinomas were included in this retrospective analysis. Only patients with known HPV status were eligible for the investigation. Survival probabilities were estimated for different risk factors. Results Eighty-five patients presented with laryngeal carcinoma and 49 patients with hypopharyngeal carcinoma. 8% were HPV positive (10.6% laryngeal, 4.1% hypopharyngeal carcinoma). Median follow-up time was 58 months. We observed a significantly better overall survival for patients with an early tumor stage compared to advanced carcinoma. One of the hypopharyngeal HPV positive carcinomas was also p16 positive and one was p16 negative. Of the nine HPV positive laryngeal carcinomas, four were p16 positive and five p16 negative. Neither patients who were HPV positive nor patients positive for p16 showed a significantly better outcome than HPV or p16 negative patients. In contrast, nicotine pack-years showed a highly significant correlation with survival in our patient collective. Conclusions The data suggest that tumor stage and nicotine exposure seem to have the highest impact on survival in hypopharyngeal and laryngeal squamous cell carcinoma patients. There is no evidence for a better survival for p16 positive or HPV positive patients with hypopharyngeal or laryngeal squamous cell carcinoma. HPV seems to play a minor role in these entities of head and neck carcinoma.

Abstract
This study is to investigate the methylation status of multiple tumor suppressor 1 (p16), secreted glycoprotein 2 (SLIT2), scavenger receptor class A, member 5 putative (SCARA5), and human runt-related transcription factor 3 (Runx3) genes in the peripheral blood of hepatocellular carcinoma (HCC).This is a case-control study. The peripheral blood samples were collected from 25 HCC patients, 25 patients with high risk of HCC (defined as "internal control group"), and 25 healthy individuals (defined as "external control group"), respectively. Then the methylation status of p16, SLIT2, SCARA5, and Runx3 genes in the blood samples were analyzed by pyrosequencing. The relationship between the methylation and the clinical features of HCC patients were evaluated.The methylation levels in the 7 CpG loci of p16 gene in HCC patients were low and without statistically significant difference (P > .05) compared to the control groups. Although the methylation levels of CpG3 and CpG4 in SLIT2 gene loci were higher than those of the control groups, there was no statistically significant difference (P > .05). However, the methylation rate of CpG2 locus in SCARA5 gene in HCC patients was significantly higher (P < .05). And the methylation rates of CpG1, CpG2, CpG3, CpG4, CpG5, and CpG8 in Runx3 gene in HCC patients were significantly different to that of control groups (P < .05). We also have analyzed the correlations between the CpG islands methylation of Runx3 or SCARA5 genes and the age, gender, hepatitis B, liver cirrhosis, alpha fetal protein, or hepatitis B surface antigen (HBsAg) of the HCC patients, which all showed no significant correlations (P > .05).The methylation status of SCARA5 and Runx3 genes are abnormal in HCC patients, which may further be used as molecular markers for early auxiliary diagnosis of liver cancer.

Abstract
BACKGROUND p16(INK4a) methylation present in the tumors of colorectal cancer (CRC) patients can be detected in their serum using quantitative methylation-specific PCR (Q-MSP). To investigate the possibility that this technique could be applied to the monitoring for cancer recurrence in CRC patients, p16(INK4a) methylation in the serum of CRC patients during their follow-up period was evaluated. MATERIALS AND METHODS Using Q-MSP on serum samples from 21 CRC patients undergoing surgery for primary CRC, the p16INK4a methylation score (p16(INK4a) MS) was evaluated one day before surgery and during the follow-up period. RESULTS In the serum samples collected before primary resection, p16(INK4a) methylation was detected in 8 out of the 13 patients with same methylation in the tumor. The p16(INK4a) MS decreased within 2 weeks after surgery. Only two patients, who had the potential for recurrence, exhibited p16(INK4a) methylation in their serum. One month after surgery, in the patients with recurrence of tumor, a dramatic increase in p16(INK4a) MS was observed, while in the disease-free patients no methylation was seen continuously. CONCLUSION p16(INK4a) MS could sensitively reflect the recurrence status and may be useful for identifying the presence of recurrence during the follow-up of CRC patients.

Abstract
BACKGROUND The present study was performed to estimate the frequency of methylated p16INK4A in the sera of patients with hepatitis C virus (HCV)-related chronic active hepatitis (CAH), liver cirrhosis (LC), and hepatocellular carcinoma (HCC) and to evaluate the role of p16INK4A as a tumor marker of HCC. MATERIAL/METHODS The sera of 17 CAH, 20 LC, and 25 HCC patients were examined in this study. The methylation status of p16INK4A was evaluated by methylation-specific PCR of the serum samples. RESULTS Methylated p16INK4A was detected in 47.1% (8/17) of the CAH patients, 5% (4/20) of the LC patients, and in 92% (23/25) of the HCC patients. HBV markers were detected in (4/25) of HCC patients; all had methylated p16INK4A. No association was demonstrated between p16INK4A methylation and serum AFP level in the HCC group. CONCLUSIONS The results of this study indicate that aberrant DNA methylation contributes to hepatocarcinogenesis and it may be an early event during hepatocarcinogenesis. As the status of p16INK4A methylation was not associated with serum AFP level, it may have a complementary role with AFP as a tumor marker of HCC.

Abstract
Expression of the p16(INK4a) tumor suppressor sharply increases with age in most mammalian tissues, and contributes to an age-induced functional decline of certain self-renewing compartments. These observations have suggested that p16(INK4a) expression could be a biomarker of mammalian aging. To translate this notion to human use, we determined p16(INK4a) expression in cellular fractions of human whole blood, and found highest expression in peripheral blood T-lymphocytes (PBTL). We then measured INK4/ARF transcript expression in PBTL from two independent cohorts of healthy humans (170 donors total), and analyzed their relationship with donor characteristics. Expression of p16(INK4a), but not other INK4/ARF transcripts, appeared to exponentially increase with donor chronologic age. Importantly, p16(INK4a) expression did not independently correlate with gender or body-mass index, but was significantly associated with tobacco use and physical inactivity. In addition, p16(INK4a) expression was associated with plasma interleukin-6 concentration, a marker of human frailty. These data suggest that p16(INK4a) expression in PBTL is an easily measured, peripheral blood biomarker of molecular age.

Abstract
BACKGROUND We investigated the hypermethylation status in serum of sporadic breast cancer patients. MATERIAL AND METHODS The hypermethylation status of BRCA1, p16 and 14-3-3sigma in cancerous tissues and the paired serum of 38 sporadic breast cancer patients was examined by methylation-specific PCR (MSP) assay. Normal and benign tissue and serum control DNA were also examined to determine the specificity of hypermethylation. RESULTS Hypermethylation of 1 or more genes was found in 36/38 (95%) of sporadic breast cancers. BRCA1 was hypermethylated in 14/38 (37%), p16 in 13/38 (34%), and 14- 3-3sigma in 33/38 (87%) of cancerous tissues. 71% of the corresponding serum DNA was positive for hypermethylation, including all histological types, stages and grades. No methylated products of BRCA1, p16 and 14-3-3sigma were observed in serum DNA from healthy women and patients with benign tissue specimens. A gene unmethylated in the tumor DNA was always found to be unmethylated in matched serum DNA. CONCLUSIONS Hypermethylation of BRCA1, p16 and 14-3-3sigma is present in all histologic types, stages and grades in sporadic breast cancer and can be detected in serum DNA. It signifies that serum-based hypermethylation screening may enhance early detection of sporadic breast cancer.

Abstract
In the detection of DNA hypermethylation as a tumor-specific epigenetic change in blood mononuclear cell fraction in patients with lymphoid and hematopoetic disorders, circulating tumor cells originating from the lymph nodes or bone marrow can be identified. However, it is still not clear whether methylation in mononuclear cells is disease specific. In the present study, we investigated whether methylation of the inhibitor of cyclin-dependent kinase (INK) 4A/alternative reading frame (ARF) locus is present in a disease-specific manner in the blood mononuclear cell fraction of patients with lymphoma, multiple myeloma, or leukemia. To increase the sensitivity of detection, a two-step methylation-specific PCR approach was used to analyze the methylation status of the promoter/exon 1 regions of both p14ARF and p16INK4A genes. Our findings indicate that although INK4A/ARF locus methylation is present in mononuclear cells, this event is not disease-specific since normal subjects also display methylated DNA in their mononuclear cells. In 85.1% of the patients and in 89% of the controls, p16INK4A gene was methylated, while the methylation rates for the p14ARF gene was 32.6 and 36.5%, respectively. The presence of methylated CpG sites in DNA in samples from normal subjects was confirmed by bisulfite genomic sequencing. The difference in the methylation rate between p16INK4A and p14ARF genes among the patients was highly significant (p<0.001). Our results demonstrate that methylation of the INK4A/ARF locus is not a disease-specific molecular change in mononuclear cell fraction and that the p14ARF and p16INK4A genes are differentially methylated.

Abstract
BACKGROUND/AIMS This study was designed to compare a methylation-specific polymerase chain reaction (MSP) assay for three genes [p16, E-cadherin, and retinoic acid receptor beta (RARbeta)] and conventional serum tumor markers using blood samples from gastric cancer patients. METHODOLOGY Preoperative blood samples obtained from 63 consecutive patients with gastric cancer were subjected to MSP and conventional serum marker assays. RESULTS MSP assay detected hypermethylation of p16 in 17 patients (27%), E-cadherin in 15 patients (24%), and RARbeta in 11 patients (17%). Altogether, 32 patients (51%) showed hypermethylation in serum samples. By contrast, only 21 (33%) patients exhibited elevations of serum carcinoembryonic antigen or carbohydrate antigen 19-9. There was no correlation between MSP results and conventional tumor markers. CONCLUSIONS The detection rate for MSP was higher than that of conventional tumor markers in serum of gastric cancer patients. Both assays can serve as complementary markers that allow for selection of cases requiring more intensive screening or aggressive postoperative treatment.

Abstract
Hepatocellular carcinomas (HCCs) show genomic alterations, including DNA rearrangements associated with HBV DNA integration, loss of heterozygosity, and chromosomal amplification. The genes most frequently involved are those encoding tumor suppressors. The p16INK4A tumor suppressor gene frequently displays genetic alteration in HCC tissues. The present study was performed to examine the incidence of methylated p16INK4A in the sera of liver cirrhosis (LC) and HCC patients, and to evaluate its role as a tumor marker of HCC. The sera of 23 LC patients and 46 HCC patients were examined in this study. The methylation status of p16INK4A was evaluated by methylation-specific PCR of serum samples. Methylated p16INK4A was detected in 17.4% (4/23) of LC patients and in 47.8% (22/46) of HCC patients. No association was demonstrated between p16INK4A methylation and serum AFP level. As the status of p16INK4A methylation was not associated with serum AFP level, it may have a role as a tumor marker of HCC.

Abstract
We examined by immunoblotting antibodies that bind to p16INK4A tumor suppressor gene products in the sera of patients with lung cancer. Sera from 15 to 102 patients, including 6 with adenocarcinoma, 3 with squamous cell carcinoma, 2 with large cell carcinoma and 4 with small cell carcinoma, reacted with a glutathione-S-transferase (GST) fusion protein containing whole human anti-p16INK4A, produced by Escherichia coli. However, sera from 30 normal volunteers did not react with the GST-p16INK4A fusion protein. The background such as age, gender, performance status, histology, stage, smoking history, and prior treatment was not significantly different between the patients with and without anti-GST-p16INK4A antibodies. Circulating p16INK4A tumor suppressor products were not detected in any individuals with lung cancer or in the normal controls.
