Negative results from randomized trials of EGFR inhibitors (EGFRi) in patients with molecularly unselected GEA have hampered the development of EGFRi in the gastroesophageal cancer space. A recent study reopens the game.See related article by Corso et al., p. 3126.Eukaryotic nucleosomes organize chromatin by wrapping 147 bp of DNA around a histone core particle comprising two molecules each of histone H2A, H2B, H3 and H4. The DNA entering and exiting the particle may be bound by the linker histone H1. Whereas deposition of bulk histones is confined to S-phase, paralogs of the common histones, known as histone variants, are available to carry out functions throughout the cell cycle and accumulate in post-mitotic cells. Histone variants confer different structural properties on nucleosomes by wrapping more or less DNA or by altering nucleosome stability. selleck chemicals They carry out specialized functions in DNA repair, chromosome segregation and regulation of transcription initiation, or perform tissue-specific roles. In this Cell Science at a Glance article and the accompanying poster, we briefly examine new insights into histone origins and discuss variants from each of the histone families, focusing on how structural differences may alter their functions.

We investigated whether preoperative and postoperative levels of inflammation markers, which have mechanistically been linked to colorectal cancer progression, were associated with recurrence and all-cause mortality in patients with colorectal cancer.

Data of two prospective cohort studies were used. For the current analysis, patients with stage I to III colorectal cancer were considered. Data on inflammation [IL6, IL8, IL10, TNFα, high-sensitivity C-reactive protein (hsCRP), and a combined inflammatory

-score] were available for 747 patients before surgery and for 614 patients after surgery. The associations between inflammation marker levels and colorectal cancer recurrence and all-cause mortality were examined using multivariable Cox proportional hazard regression models, considering patient characteristics and clinical and lifestyle factors.

Higher preoperative and postoperative hsCRP levels were associated with a higher risk of recurrence [HR

(95% CI), 1.15 (1.02-1.30) and 1.34 (1.16-1.55)] and all-cause mortality [HR

(95% CI) 1.13 (1.01-1.28) and 1.15 (0.98-1.35)]. A doubling in IL8 levels (preoperative levels HR = 1.23; 95% CI, 1.00-1.53 and postoperative levels HR = 1.61; 95% CI, 1.23-2.12) and a higher combined inflammatory

-score (preoperative HR

= 1.39; 95% CI, 1.03-1.89 and postoperative HR

= 1.56; 95% CI, 1.06-2.28) were associated with a higher risk of all-cause mortality, but not recurrence. No associations between IL6, IL10, and TNFα and recurrence or all-cause mortality were observed.

Preoperative and postoperative levels of specific inflammation markers were associated with recurrence and/or all-cause mortality.

The complex role of inflammation in cancer recurrence merits further elucidation by investigating local inflammation at the tumor site.

Estrogens are thought to contribute to breast cancer risk through cell cycling and accelerated breast aging. We hypothesize that lifetime estrogen exposure drives early epigenetic breast aging observed in healthy women. In this study, we examined associations between hormonal factors and epigenetic aging measures in healthy breast tissues.

We extracted DNA from breast tissue specimens from 192 healthy female donors to the Susan G. Komen Tissue Bank at the Indiana University Simon Cancer Center. Methylation experiments were performed using the Illumina EPIC 850K array platform. Age-adjusted regression models were used to examine for associations between factors related to estrogen exposure and five DNA methylation-based estimates Grim age, pan-tissue age, Hannum age, phenotypic age, and skin and blood clock age.

Women were aged 19-90 years, with 95 premenopausal, and 97 nulliparous women. The age difference (Grim age – chronologic age) was higher at earlier ages close to menarche. We found significant associations between earlier age at menarche and age-adjusted accelerations according to the Grim clock, the skin and blood clock, and between higher body mass index (BMI) and age-adjusted accelerations in the Grim clock, Hannum clock, phenotypic clock, and skin and blood clock.

Earlier age at menarche and higher BMI are associated with elevations in DNA methylation-based age estimates in healthy breast tissues, suggesting that cumulative estrogen exposure drives breast epigenetic aging.

Epigenetic clock measures may help advance inquiry into the relationship between accelerated breast tissue aging and an elevated incidence of breast cancer in younger women.

Risk prediction models offer a promising approach to lifestyle modification. We evaluated the effect of personalized advice based on cancer risk prediction in improving five lifestyle habits (smoking, alcohol consumption, salt intake, physical activity, and body mass index) compared with standard advice without risk prediction among a Japanese general population with at least one unhealthy lifestyle habit.

In a parallel-design, single-blind, randomized controlled trial between February 2018 and July 2019, 5984 participants aged 40-64 years with unhealthy lifestyle habits were recruited from persons covered under a life insurance policy. They were randomly assigned to an intervention or control group and received personalized or standard advice, respectively. They were also sent an invitation to participate in a lifestyle modification program aimed at improving lifestyle. Primary outcome was an improvement in lifestyle, defined as an increase in healthy lifestyle habits within 6 months.

The proportion of participants who improved their lifestyle within 6 months in the intervention group did not significantly differ from that in the control group (18.
