Article Abstract
We have performed ac susceptibility and dc magnetization measurements in Ni(50-x)Co(x)Mn(38)Sb(12) Heusler alloys. From the ac susceptibility measurements, the existence of reentrant spin glass (RSG) state is observed for x=0-5. It is found that the signature of RSG behavior diminishes with increase in x. This behavior is in contrast to the fact that the exchange bias field increases with x, which reveals that the origins of RSG and exchange bias are different in the present system. It is found that the system enters a frustrated ferromagnetic state just below the Curie temperature of the martensite phase (T(M)(C)) and then the RSG state at low temperature. The strength of the RSG state is critically dependent on the sharpness of the magnetic transition at (T(M)(C)). This proposition is further supported by the thermo-remanent magnetization and low field thermomagnetic measurements.

Immune checkpoint inhibitors (ICIs) and their combination with other therapies such as chemotherapy, fail in most cancer patients. We previously identified the PDZ-LIM domain-containing protein 2 (PDLIM2) as a bona fide tumor suppressor that is repressed in lung cancer to drive cancer and its chemo and immunotherapy resistance, suggesting a new target for lung cancer therapy improvement. In this study, human clinical samples and data were used to investigate genetic and epigenetic changes in lung cancer.

Biomolecular condensates (BCs) are crucial membraneless organelles formed through the process of liquid-liquid phase separation (LLPS) involving proteins and nucleic acids. These LLPS processes are tightly linked with essential cellular activities. Stress granules (SGs), functioning as cytoplasmic BCs, play indispensable roles in maintaining cellular homeostasis and are implicated in diseases like cancers and neurodegenerative disorders.

Background: Amino acids are critical to tumor survival. Tumors can acquire amino acids from the surrounding microenvironment, including the serum. Limiting dietary amino acids is suggested to influence their serum levels.

Circulating tumor cells (CTCs) travel through the vasculature to seed secondary sites and serve as direct precursors of metastatic outgrowth for many solid tumors. Heterotypic cell clusters form between CTCs and white blood cells (WBCs) and recent studies report that a majority of these WBCs are neutrophils in patient and mouse models. The lab discovered that CTCs produce tubulin-based protrusions, microtentacles (McTNs), which promote reattachment, retention in distant sites during metastasis and formation of tumor cell clusters.

Little is known about the impact of low- to moderate-penetrance genetic testing for skin cancer, which is a promising approach to skin cancer prevention. To address this deficit, we conducted an analysis comparing changes in skin cancer-related behaviors, distress, and beliefs measured at a baseline and twice after the receipt of skin cancer precision prevention materials containing risk feedback (higher or average risk) among 568 non-Hispanic White (NHW) and 463 Hispanic participants. Regression analyses identified decreased average weekend hours in the sun (β = -0.
