Oncogenic and microenvironmental signals drive cell type specific apoptosis resistance in juvenile myelomonocytic leukemia.

Juvenile myelomonocytic leukemia (JMML) is caused by constitutively activated RAS signaling and characterized by increased proliferation and predominant myelomonocytic differentiation of hematopoietic cells. Using MxCre;Ptpn11 mice, which model human JMML, we show that RAS pathway activation affects apoptosis signaling through cell type-dependent regulation of BCL-2 family members. Apoptosis resistance observed in monocytes and granulocytes was mediated by overexpression of the anti-apoptotic and down-regulation of the pro-apoptotic members of the BCL-2 family.

The Landscape of Supportive Care Needs Among Prostate Cancer Patients in New Zealand: A Cross-Ethnic Analysis.

Background: Prostate cancer (PCa) is a significant health burden within New Zealand (NZ). Survival gains from prostate cancer have created a shift in focus from survival towards quality of life (QoL) and supportive care during extended survivorship.

Method: We launched a nation-wide cross-sectional survey and recruited three cohorts of 1000 men with prostate cancer (men diagnosed with prostate cancer within 1 year, between 1 and 3 years, and between 3 and 5 years) as well as an additional Māori men group (N = 4000 in total).

Tailoring the special hole transfer layer between BiVO and oxygen evolution co-catalysts interfaces for boosting photoelectrochemical water splitting.

Tailoring the hole transport layer (HTL) between BiVO (BVO) and oxygen evolution co-catalysts (OECs) interfaces is a leading strategy to improve the performance of photoelectrochemical (PEC) water splitting. Nevertheless, the limited driving force at the BVO/OECs interfaces severely hinders the transport of charge carriers. In this study, we designed a specialized defective transition metal oxide (Vo-MnO) as the HTL.

Short IL-18 generated by caspase-3 cleavage mobilizes NK cells to suppress tumor growth.

Interleukin (IL)-18 functions primarily through its 18-kDa mature form produced from caspase-1 cleavage. However, IL-18 can also be processed by other proteases, leading to the generation of different fragments with less recognized functions. Here, we discover that, in cancer cells, caspase-3 cleavage of IL-18 generates a 15-kDa form of IL-18, referred to as short IL-18.

SAA3 deficiency exacerbates intestinal fibrosis in DSS-induced IBD mouse model.

Intestinal fibrosis, as a late-stage complication of inflammatory bowel disease (IBD), leads to bowel obstruction and requires surgical intervention, significantly lowering the quality of life of affected patients. SAA3, a highly conserved member of the serum amyloid A (SAA) apolipoprotein family in mice, is synthesized primarily as an acute phase reactant in response to infection, inflammation and trauma. An increasing number of evidence suggests that SAA3 exerts a vital role in the fibrotic process, even though the underlying mechanisms are not yet fully comprehended.

Self-assembled materials with an ordered hydrophilic bilayer for high performance inverted Perovskite solar cells.

While self-assembled material based inverted perovskite solar cells have surpassed power conversion efficiencies of 26%, enhancing their performance in large-area configurations remains a significant challenge. In this work, we report a self-assembled material based hole-selective layer 4-(7H-dibenzo[c,g]carbazol-7-yl)phenyl)phosphonic acid, with a π-expanded conjugation. The enhanced intermolecular π-π interactions facilitate the self-assembly of 4-(7H-dibenzo[c,g]carbazol-7-yl)phenyl)phosphonic acid molecules to form an ordered bilayer with a hydrophilic surface, which passivates the buried perovskite interface defect and enables high-quality and large-area perovskite preparation, while simultaneously enhancing interfacial charge extraction and transport.

Predicting Source Rock Distribution of the Ninth Member of the Upper Triassic Yanchang Formation Based on Well-Logging Parameters and TOC Values in the Longdong Area, Ordos Basin, China.

In recent years, new oil reservoirs have been discovered and exploited in the ninth member (Chang 9 Member, Ty) of the Upper Triassic Yanchang Formation (Ty) in the Longdong area, Ordos Basin. Some studies have shown that the crude oils of the Chang 9 Member may originate from the Chang 9 source rock in some areas, which may be related to the distribution of the source rock. However, the distribution of the Chang 9 source rock in the Longdong area is still unclear, which hinders further exploration and development of petroleum.
