PHLPP1 depletion promotes tumorigenesis and stemness in triple-negative breast cancer cells through AKT signaling.

Breast cancer, particularly triple-negative breast cancer (TNBC), is a major cause of women's mortality, and effective treatment options are still lacking due to the absence of known mechanisms and biomarkers. Therefore, unveiling novel molecular mechanisms to identify potential biomarkers is urgently needed to ensure an effective TNBC treatment. In this study, we investigated the role of PHLPP1, a tumor suppressor gene, in the tumorigenesis and induction of cancer stem cells in TNBC using publicly available data and experimental protocols.

Association of the corona virus (Covid-19) epidemic with environmental risk factors.

The current outbreak of the novel coronavirus SARS-CoV-2 (coronavirus disease 2019; previously 2019-nCoV), epicenter in Hubei Province (Wuhan), People's Republic of China, has spread too many other countries. The transmission of the corona virus occurs when people are in the incubation stage and do not have any symptoms. Therefore, the role of environmental factors such as temperature and wind speed becomes very important.

Method for retrieving range-resolved aerosol microphysical properties from polarization lidar measurements.

Aerosol microphysical properties, such as volume concentration (VC) and effective radius (ER), are of great importance to evaluate their radiative forcing and impacts on climate change. However, range-resolved aerosol VC and ER still cannot be obtained by remote sensing currently except for the column-integrated one from sun-photometer observation. In this study, a retrieval method of range-resolved aerosol VC and ER is firstly proposed based on the partial least squares regression (PLSR) and deep neural networks (DNN), combining polarization lidar and collocated AERONET (AErosol RObotic NETwork) sun-photometer observations.
