The Maf proteins (Mafs) belong to basic leucine zipper transcription factors and are members of the activator protein-1 (AP-1) superfamily. There are two subgroups of Mafs: large Mafs and small Mafs, which are involved in a wide range of biological processes, such as the cell cycle, proliferation, oxidative stress, and inflammation. Therefore, dysregulation of Mafs can affect cell fate and is closely associated with diverse diseases. Accumulating evidence has established both large and small Mafs as mediators of tumor development. In this review, we first briefly describe the structure and physiological functions of Mafs. Then we summarize the upstream regulatory mechanisms that control the expression and activity of Mafs. Furthermore, we discuss recent studies on the critical role of Mafs in cancer progression, including cancer proliferation, apoptosis, metastasis, tumor/stroma interaction and angiogenesis. We also review the clinical implications of Mafs, namely their potential possibilities and limitations as biomarkers and therapeutic targets in cancer.

Aims: Clopidogrel exhibits substantial variability in therapeutic response, largely contributed by genetic factors. The pharmacogenomic variants data on clopidogrel metabolism in South Asians have been sparsely studied. This study explores the impact of and gene variants on clopidogrel metabolism in Sri Lankans, revealing significant pharmacogenomic insights with broader implications for South Asians.

Sabah has the highest prevalence of β-thalassemia in Malaysia, with the Filipino β-deletion as the predominant mutation. Patients with the homozygous Filipino β-deletion exhibit phenotypic heterogeneity due to various genetic modifiers, yet the effects of these modifiers on the clinical phenotype remain poorly understood. This study investigated the effects of the coinheritance of α-thalassemia, I-γ rs7482144, rs766432, and 5'HS4 rs16912979 polymorphisms on the clinical phenotype of homozygous Filipino β-deletion patients in Sabah.

Background: Atrazine (ATZ), a pesticide that poses serious health problems, is observed in the environment, thereby prompting its periodic monitoring and control using functional biosensors. However, established methods for ATZ detection have limited applicability. Two-dimensional (2D) metal azolate frameworks (MAF) have a higher surface area per unit volume and provide easier access to active sites.

Polarization multispectral imaging has advanced significantly due to its robust information representation capability. Imaging application requires rigorous simulation evaluation and experimental validation using standardized datasets. However, the current full-Stokes polarization multispectral images (FSPMI) dataset, while providing simulation data, is limited by image drift and spectral bands.

In this work, we developed a highly accurate and sensitive two-emission fluorescence sensor, integrated with a smartphone, for the rapid detection of Cu and Cr in aqueous solution. This sensor comprised AgInS/ZnS quantum dots (AIS/ZnS QDs) and metal-AIEgen frameworks (MAFs). Upon mixing in a specific ratio, the hybrid system can emit a white light when exposed to a UV lamp (365 nm).
