The SARI (suppressor of AP-1, regulated by IFN) gene, which is also called BATF2, is associated with the risk of several kinds of cancer, and loss of SARI expression is frequently detected in aggressive and metastatic cancer. However, the functional role of SARI in lung adenocarcinoma remains unknown. ⋯ Moreover, we showed that SARI functions as a critical protein in regulating EMT by modulating the (GSK)-3β-β-catenin signaling pathway. These results demonstrate the mechanism of SARI function in EMT and suggest that assessment of SARI may serve as a prognostic biomarker and potential therapeutic target for lung adenocarcinoma metastasis.

Natural killer cells, as a major source of interferon-γ, contribute to the amplification of the inflammatory response as well as to mortality during severe sepsis in animal models. ⋯ Extensive monitoring of the NK-cell phenotype and function in critically-ill septic patients revealed early decreased NK-cell function with impaired interferon-γ production. These results may aid future NK-based immuno-interventions.

The relationship between telomere length and mortality in chronic obstructive pulmonary disease (COPD).
Some have suggested that chronic obstructive pulmonary disease (COPD) is a disease of accelerated aging. Aging is characterized by shortening of telomeres. The relationship of telomere length to important clinical outcomes such as mortality, disease progression and cancer in COPD is unknown. ⋯ Smoking status did not make a significant difference in peripheral blood cells telomere length. In conclusion, COPD patients have short leukocyte telomeres, which are in turn associated increased risk of total and cancer mortality. Accelerated aging is of particular relevance to cancer mortality in COPD.

Whether face perception involves domain-specific or domain-general processing is an extensively debated issue. Relative to non-face objects and alphabetical scripts, Chinese characters provide a good contrast to faces because of their structural configuration, requirement for high level of visual expertise to literate Chinese people, and unique appearance and identity for each individual stimulus. To examine potential categorical differences in their neural processing, event-related potentials (ERPs) were recorded to blocked face and Chinese character stimuli. ⋯ Moreover, faces elicited a larger and later P1 and a larger adaptation-by-rate effect on P1 relative to characters. The adaptation-by-orientation effect was illustrated by a larger P1 under the same relative to the alternated orientation condition. Therefore, evidence from the amplitude and the lateralization of N170, the stimulus inversion effect on N170 latency, and the neural adaptation between faces and Chinese characters on P1 and N170 components support the notion that the processing of faces and Chinese characters involve categorically different neural mechanisms.
