Homoharringtonine demonstrates a cytotoxic effect against triple-negative breast cancer cell lines and acts synergistically with paclitaxel.

The lack of targeted therapies for triple-negative breast cancer (TNBC) contributes to their high mortality rates and high risk of relapse compared to other subtypes of breast cancer. Most TNBCs (75%) have downregulated the expression of CREB3L1 (cAMP-responsive element binding protein 3 like 1), a transcription factor and metastasis suppressor that represses genes that promote cancer progression and metastasis. In this report, we screened an FDA-approved drug library and identified four drugs that were highly cytotoxic towards HCC1806 CREB3L1-deficient TNBC cells.

Reduced CREB3L1 expression in triple negative and luminal a breast cancer cells contributes to enhanced cell migration, anchorage-independent growth and metastasis.

Women with metastatic breast cancer have a disheartening 5-year survival rate of only 28%. CREB3L1 (cAMP-responsive element binding protein 3 like 1) is a metastasis suppressor that functions as a transcription factor, and in an estrogen-dependent model of rat breast cancer, it repressed the expression of genes that promote breast cancer progression and metastasis. In this report, we set out to determine the expression level of CREB3L1 across different human breast cancer subtypes and determine whether CREB3L1 functions as a metastasis suppressor, particularly in triple negative breast cancers (TNBCs).

People living with moderate-to-severe COPD prefer improvement of daily symptoms over the improvement of exacerbations: a multicountry patient preference study.

Introduction: This patient preference study sought to quantify the preferences of people living with COPD regarding symptom improvement in the UK, USA, France, Australia and Japan.

Methods: The inclusion criteria were people living with COPD aged 40 years or older who experienced ≥1 exacerbation in the previous year with daily symptoms of cough and excess mucus production. The study design included: 1) development of an attributes and levels grid through qualitative patient interviews; and 2) implementation of the main online quantitative survey, which included a discrete choice experiment (DCE) to allow assessment of attributes and levels using hypothetical health state profiles.

Social character, interdependence, and the dualities of other-directedness.

David Riesman's exploration of the other-directed characterological form, suited to corporate capitalism and the rise of the service sector, became one of the most influential sociological analyses of the twentieth century. Yet sociologists interested in the contemporary fate of those dispositional qualities suited to mutual adjustment confront a paradox: why, in an age of increasing interdependencies apparently conducive to the sustenance of other-directedness, are we witnessing rising concerns about the resurgence of social sectarianism? Most accounts of this tension rely upon structuralist explanations of late modernity's disruptive impact, or psychologistic accounts of group allegiance. In contrast, we develop a meso-level analysis that highlights an increasingly consequential duality at the heart of other-directedness itself: the qualities associated with this characterological form still facilitate selective forms of mutuality, but the demands it places upon people in the current era have also prompted growing levels of resentment and antagonism.

New Graduate Registered Nurses and the Spectrum of Comfort in Clinical Practice.

The comfort zone is where a person consistently performs his or her role in an affective state devoid of anxiety and without a feeling of risk. This study challenges the notion of a singular comfort zone and suggests that a spectrum of comfort is a more accurate reflection of the new graduate experience. A grounded theory methodology was used to identify and explain the spectrum of comfort considerations helpful to nine new graduates amid their transition to professional practice.
