However, the auxin transport mechanisms in horticultural crops remain largely unexplored.

Abemaciclib Plus Fulvestrant in Advanced Breast Cancer Following Progression on CDK4/6 Inhibition: Results from the Phase III postMONARCH Trial.

Purpose: Cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) combined with endocrine therapy (ET) are the standard first-line treatment for hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer (ABC); however, disease progression occurs in almost all patients and additional treatment options are needed. Herein we report outcomes of the postMONARCH trial investigating a switch in ET with/without CDK4/6 inhibition with abemaciclib after disease progression on CDK4/6i.

Methods: This double-blind, randomized Phase III study enrolled patients with disease progression on prior CDK4/6i plus aromatase inhibitor as initial therapy for advanced disease or recurrence on/after adjuvant CDK4/6i+ET.

Fra-1 affects chemotherapy sensitivity by inhibiting ferroptosis in gastric cancer cells.

Gastric cancer (GC) is one of the common malignant tumors, and most patients with advanced GC often develop chemotherapy resistance, resulting in poor chemotherapy efficacy. Therefore, it is crucial to clarify the specific mechanisms of their chemotherapy resistance. In this study, we analyzed the correlation between fos-related antigen-1 (Fra-1) and chemotherapy resistance in GC using bioinformatics, cell counting kit-8 (CCK8), and 5-ethynyl-2'-deoxyuridine (EDU) combined with flow cytometry; furthermore, we used energy metabolomics sequencing, combined with ChIP-qPCR technology, to elucidate the specific role of Fra-1 in chemotherapy resistance of GC cells and its related mechanisms.

Advancements in the Study of the Immune Molecule NKp46 in Immune System-related Diseases.

NKp46 is a natural killer cell activating receptor primarily expressed on NK cells and non-NK innate lymphoid cells. In the context of anti-infection, NKp46 activates NK cells by binding to ligands on pathogens or infected cells, enabling NK cells to kill the infected cells. In antitumor activities, NKp46 plays a pivotal role in combating tumor growth through mechanisms such as directly killing tumor cells, inhibiting tumor immune escape, and reducing tumor growth rate through immune editing.

Realizing Kirchhoff's superposition law of light-irradiated pure spin currents in paralleled graphene nanoribbons.

Multifunctional acyltransferase HBO1: a key regulatory factor for cellular functions.

HBO1, also known as KAT7 or MYST2, is a crucial histone acetyltransferase with diverse cellular functions. It typically forms complexes with protein subunits or cofactors such as MEAF6, ING4, or ING5, and JADE1/2/3 or BRPF1/2/3, where the BRPF or JADE proteins serve as the scaffold targeting histone H3 or H4, respectively. The histone acetylation mediated by HBO1 plays significant roles in DNA replication and gene expression regulation.

However, strategies for mining or engineering of PET hydrolases with better characteristics and the simple and cost-effective preparation of them are the bottlenecks currently.

CD38 symmetric dimethyl site R58 promotes malignant tumor cell immune escape by regulating the cAMP-GSK3β-PD-L1 axis.

In recent years, immunotherapy has emerged as an effective approach for treating tumors, with programmed cell death ligand 1 (PD-L1)/programmed cell death protein-1 (PD-1) immune checkpoint blockade (ICB) being a promising strategy. However, suboptimal therapeutic efficacy limits its clinical benefit. Understanding the regulation mechanism of PD-L1 expression is crucial for improving anti-PD-L1/PD-1 therapy and developing more effective tumor immunotherapy.

SlBTB19 interacts with SlWRKY2 to suppress cold tolerance in tomato via the CBF pathway.

Cold stress restricts the metabolic and physiological activities of plants, thereby affecting their growth and development.
