Pięta B, Bień A, Pięta M, Żurawska J, Rzymski P, Wilczak M. Eating Behaviors and Physical Activity versus the Big Five Personality Traits in Women with a Hereditary Predisposition to Breast or Ovarian Cancer. Nutrients 2024; 16:1244. [PMID: 38674934 PMCID: PMC11053837 DOI: 10.3390/nu16081244] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2024] [Revised: 04/16/2024] [Accepted: 04/18/2024] [Indexed: 04/28/2024] Open
Abstract
The Big Five personality traits-neuroticism, extroversion, openness to experience, agreeableness, and conscientiousness-represent continuous, individual features that affect a number of vital health aspects, including morbidity, self-reported health status, or lifestyle. The aim of this study was to analyze the relationship between the eating behaviors and engagement in physical activity of women with a hereditary predisposition to breast or ovarian cancer and the Big Five personality traits. A total of 357 women, participants of 'The National Program for Families With Genetic/Familial High Risk for Cancer', were included in the study. In the healthy group, the following statistically significant predictors were found in variables: agreeableness-meal frequency (β = 0.151; p = 0.030); neuroticism-consumption of fruits and vegetables (β = -0.177; p = 0.016) and cereal products (β = -0.223; p = 0.002); openness to experience-consumption of plant-based fats (β = 0.141; p = 0.034) and physical activity (β = 0.153; p = 0.021). In the cancer group, the frequency of dairy consumption (β = 0.286; p = 0.003) and physical activity (β = 0.370; p = 0.000) were found to be statistically significant predictors for the openness to experience variable. Neuroticism is associated with less frequent consumption of fresh fruits and vegetables as well as cereal products. Openness to experience was more often linked with a higher frequency of dairy consumption, plant-based fats, and physical activity. Women with breast or ovarian cancer and a higher openness to experience consumed dairy and engaged in physical activity more often than their peers with the remaining personality traits.

Abstract
Breast cancer (BC) is a multifaceted disease characterized by distinct molecular subtypes and varying responses to treatment. In BC, the phosphatidylinositol 3-kinase (PI3K) pathway has emerged as a crucial contributor to the development, advancement, and resistance to treatment. This review article explores the implications of the PI3K pathway in predictive, preventive, and personalized medicine for BC. It emphasizes the identification of predictive biomarkers, such as PIK3CA mutations, and the utility of molecular profiling in guiding treatment decisions. The review also discusses the potential of targeting the PI3K pathway for preventive strategies and the customization of therapy based on tumor stage, molecular subtypes, and genetic alterations. Overcoming resistance to PI3K inhibitors and exploring combination therapies are addressed as important considerations. While this field holds promise in improving patient outcomes, further research and clinical trials are needed to validate these approaches and translate them into clinical practice.

Abstract
Cancer is one of the leading global causes of death in both men and women. Colorectal cancer (CRC) alone accounts for ∼10 % of total new global cases and poses an over 4% lifetime risk of developing cancer. Recent advancements in the field of biotechnology and microbiology concocted novel microbe-based therapies to treat various cancers, including CRC. Microbes have been explored for human use since centuries, especially for the treatment of various ailments. The utility of microbes in cancer therapeutics is widely explored, and various bacteria, fungi, and viruses are currently in use for the development of cancer therapeutics. The human gut hosts about 100 trillion microbes that release their metabolites in active, inactive, or dead conditions. Microbial secondary metabolites, proteins, immunotoxins, and enzymes are used to target cancer cells to induce cell cycle arrest, apoptosis, and death. Various approaches, such as dietary interventions, the use of prebiotics and probiotics, and fecal microbiota transplantation have been used to modulate the gut microbiota in order to prevent or treat CRC pathogenesis. The present review highlights the role of the gut microbiota in CRC precipitation, the potential mechanisms and use of microorganisms as CRC biomarkers, and strategies to modulate microbiota for the prevention and treatment of CRC.

Abstract
BackgroundThe effect of tobacco on breast cancer (BC) is controversial. The purpose of this study was to investigate the relationship between tobacco and BC.MethodsA search was conducted in PubMed, EBSCO, Web of Science and Cochrane Library databases before February 2022. The adjusted odd ratio (OR) and corresponding 95% confidence interval (CI) were used to examine the relationship between active or passive smoking and BC risk.ResultsA total of 77 articles composed of 2,326,987 participants were included for this meta-analysis. Active (OR=1.15, 95% CI=1.11-1.20, p<0.001) and passive (OR=1.17, 95% CI=1.09-1.24, p<0.001) smoking increased the risk of BC in the female population, especially premenopausal BC (active smoking: OR=1.24, p<0.001; passive smoking: OR=1.29, p<0.001), but had no effect on postmenopausal BC (active smoking: OR=1.03, p=0.314; passive smoking: OR=1.13, p=0.218). Active smoking increased the risk of estrogen receptor-positive (ER+) BC risk (OR=1.13, p<0.001), but had no effect on estrogen receptor-negative (ER-) BC (OR=1.08, p=0.155). The risk of BC was positively associated with the duration and intensity of smoking, negatively associated with the duration of smoking cessation. Active smoking increased the risk of BC in the multiparous population (OR=1.13, p<0.001), but had no effect on the nulliparous population (OR=1.05, p=0.432), and smoking before the first birth (OR=1.22, 95% CI=1.17-1.27) had a greater impact on the risk of BC than smoking after the first birth (OR=1.08, 95% CI=1.04-1.12).ConclusionSmoking (active and passive) increased the risk of BC in women. The effect of smoking on BC was influenced by smoking-related factors (duration, intensity, years of quitting), population-related factors (fertility status), and BC subtypes.Systematic Review Registrationidentifier CRD42022322699.

Front Oncol 2021; 11:679998. [PMID: 34249719 PMCID: PMC8263909 DOI: 10.3389/fonc.2021.679998] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Accepted: 06/07/2021] [Indexed: 01/05/2023] Open
Abstract
COX and ALOX genes are involved in inflammatory processes and that may be related to breast cancer risk differentially between White and Black women. We evaluated distributions of genetic variants involved in COX2 and ALOX-related pathways and examined their associations with breast cancer risk among 1,275 White and 1,299 Black cases and controls who participated in the Women’s Circle of Health Study. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using multivariable-adjusted logistic regression models. Our results showed differential associations of certain genetic variants with breast cancer according to menopausal and ER status in either White or Black women. In White women, an increased risk of breast cancer was observed for COX2-rs689470 (OR: 2.02, P = 0.01) in the dominant model, and was strongest among postmenopausal women (OR: 2.72, P = 0.02) and for estrogen receptor positive (ER+) breast cancers (OR: 2.60, P = 0.001). A reduced risk was observed for ALOX5-rs7099874 (OR: 0.75, P = 0.01) in the dominant model, and was stronger among postmenopausal women (OR: 0.68, P = 0.03) and for ER+ cancer (OR: 0.66, P = 0.001). Four SNPs (rs3840880, rs1126667, rs434473, rs1042357) in the ALOX12 gene were found in high LD (r2 >0.98) in White women and were similarly associated with reduced risk of breast cancer, with a stronger association among postmenopausal women and for ER− cancer. Among Black women, increased risk was observed for ALOX5-rs1369214 (OR: 1.44, P = 0.003) in the recessive model and was stronger among premenopausal women (OR: 1.57, P = 0.03) and for ER+ cancer (OR: 1.53, P = 0.003). Our study suggests that genetic variants of COX2 and ALOX genes are associated with breast cancer, and that these associations and genotype distributions differ in subgroups defined by menopausal and ER status between White and Black women. Findings may provide insights into the etiology of breast cancer and areas for further research into reasons for breast cancer differences between races.

Abstract
PURPOSE This article reviews and updates the evidence on the associations between physical activity and risk for cancer, and for mortality in persons with cancer, as presented in the 2018 Physical Activity Guidelines Advisory Committee Scientific Report. METHODS Systematic reviews of meta-analyses, systematic reviews, and pooled analyses were conducted through December 2016. An updated systematic review of such reports plus original research through February 2018 was conducted. This article also identifies future research needs. RESULTS In reviewing 45 reports comprising hundreds of epidemiologic studies with several million study participants, the report found strong evidence for an association between highest versus lowest physical activity levels and reduced risks of bladder, breast, colon, endometrial, esophageal adenocarcinoma, renal, and gastric cancers. Relative risk reductions ranged from approximately 10% to 20%. Based on 18 systematic reviews and meta-analyses, the report also found moderate or limited associations between greater amounts of physical activity and decreased all-cause and cancer-specific mortality in individuals with a diagnosis of breast, colorectal, or prostate cancer, with relative risk reductions ranging almost up to 40% to 50%. The updated search, with five meta-analyses and 25 source articles reviewed, confirmed these findings. CONCLUSIONS Levels of physical activity recommended in the 2018 Guidelines are associated with reduced risk and improved survival for several cancers. More research is needed to determine the associations between physical activity and incidence for less common cancers and associations with survival for other cancers. Future studies of cancer incidence and mortality should consider these associations for population subgroups, to determine dose-response relationships between physical activity and cancer risk and prognosis, and to establish mechanisms to explain these associations.

[PMID: 30706682 PMCID: PMC6418365 DOI: 10.1002/mgg3.540] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2018] [Revised: 11/12/2018] [Accepted: 12/02/2018] [Indexed: 12/31/2022] Open
Abstract
Background Breast cancer is one of the most common types of cancer among women and the highest cause of death due to cancer among women aged 40–45. SNPs can be used to identify disease‐related genes such as cancer as they can be genetic markers. Furthermore, SNPs in the molecular‐level miRNA structure are also associated with a set of cancers. Studies have shown that miR‐323b plays a tumor suppressor role by reducing the tissues and serum of the affected individuals. So far, no study regarding rs56103835 polymorphism in the precursor of miR‐323b has been conducted in the breast cancer. In this study, the association of this SNP with the incidence of breast cancer in the Iranian population has been investigated. Method In order to correlate rs56103835 polymorphism with breast cancer, 161 patients and 162 healthy people as the control group were examined. They had been homogenized based on their age and gender. The genotype of individuals for the polymorphism was determined by the PCR‐RFLP method. The association of this polymorphism with the risk of breast cancer, the age of the onset of disease, and pathological characteristics of the patients was then analyzed. Results The findings showed that there is no significant correlation between the frequency of its genotypes among the healthy and patient populations while the TT genotype increased the age of the disease in patients, as compared to other genotypes (p = 0.035, OR = 0.487). Discussion and Conclusion The C allele is likely to inhibit the expression of BRCA2 by interfering with the processing of this pre‐miRNA and increasing the expression of target genes such as BRCA2. Because one of the early onset genes in breast cancer is the BRCA2, the presence of any of C and T alleles can have a significant effect on the incidence of the disease. To further confirm this data, however, more molecular studies are needed.

Abstract
Overweight and obesity are increasing worldwide, but the extent in breast cancer patients is unknown. The two aims were to study secular trends in preoperative body mass index (BMI), waist circumference, and breast volume and their impacts on clinical outcome. BMI, waist circumference, and breast volume were measured preoperatively in 24–99-year-old primary breast cancer patients (n = 640) in Sweden 2002–2016. The measurements were analyzed alone and combined in relation to recurrence and overall survival (OS). BMI, waist circumference, and breast volume increased 2002–2016 (ptrends < 0.0001). Of these, a breast volume ≥ 850 mL was associated with the strongest recurrence-risk (adjusted hazard ratio [adjHR] 1.67; 95% CI 1.17–2.39), especially combined with waist circumference ≥ 80 cm (adjHR 2.07; 95% CI 1.25–3.44), while BMI ≥ 25 kg/m2 or large waist circumference conferred almost a twofold risk for death (both Log-Rank p ≤ 0.0001). Chemotherapy seemed to counteract the negative impact of a high BMI or large waist circumference on OS. Large breast volume was the strongest predictor for recurrence in all treatment groups. In conclusion, preoperative BMI, waist circumference, and breast volume increased between 2002 and 2016. Larger body size negatively impacted breast cancer-free interval and OS. If confirmed, body measurements may help select patients requiring more individualized treatment.

Abstract
Breast cancer is the most common cancer among women and represents one of the top five leading causes of cancer-related mortality. Inherited and acquired genetic mutations as well as epigenetic aberrations are known to be important contributors to the development and progression of breast cancer. Recent developments in high-throughput technologies have increased our understanding of the molecular changes in breast cancer, leading to the identification of distinctive genetic and epigenetic modifications in different breast cancer molecular subtypes. These genetic and epigenetic changes in luminal A, luminal B, ERBB2/HER2-enriched, basal-like, and normal-like breast cancer subtypes are discussed in this chapter. Furthermore, recent epigenome studies provided more information about further stratification of breast cancer subtypes, with essential role in the appropriate diagnosis and treatment of breast cancer. Thus, the inclusion of both genetic and epigenetic information in breast cancer clinical care could provide critical scientific base for precision medicine in breast cancer.

Abstract
Malignant melanoma is a class of highly malignant tumors derived from melanocytes. At present, the dysregulated gene expression involved in the progression of melanoma has attracted much attention. In the present study, the gene expression profile of human melanoma tissue was screened using a cDNA microarray, and it was identified that melanocyte-specific gene 1 (MSG1) was significantly overexpressed in melanoma tissue compared with paired nevus tissues. The overexpression of MSG1 in melanoma was subsequently confirmed using immunohistochemistry in a set of melanoma tissues. It was additionally identified that the overexpression of MSG1 may promote cell viability and inhibit cell apoptosis in human melanoma A375 cells, thus promoting melanoma progression. Mechanistically, following screening of the expression of apoptosis-associated proteins, MSG1 was demonstrated to enhance the expression of the apoptosis inhibitor B-cell lymphoma 2 (Bcl-2) to inhibit melanoma cell apoptosis. Therefore, it was concluded that the overexpression of MSG1 inhibits apoptosis by enhancing Bcl-2 expression in malignant melanoma, thus promoting melanoma progression.

Abstract
Critical roles of epigenomic alterations in the pathogenesis of breast cancer have recently seized great attentions toward finding epimarkers in either non-invasive or semi-non-invasive samples as well as peripheral blood. In this way, methylated DNA immunoprecipitation microarray (MeDIP-chip) was performed on DNA samples isolated from white blood cells of 30 breast cancer patients compared to 30 healthy controls. A total of 1799 differentially methylated regions were identified including SLC6A3, Rab40C, ZNF584, and FOXD3 whose significant methylation differences were confirmed in breast cancer patients through quantitative real-time polymerase chain reaction. Hypermethylation of APC, HDAC1, and GSK1 genes has been previously reported in more than one study on tissue samples of breast cancer. Methylation of those aforementioned genes in white blood cells of our young patients not only relies on their importance in breast cancer pathogenesis but also may highlight their potential as early epimarkers that makes further assessments necessary in large cohort studies.
