Published: September 2011

Members of the genus Bifidobacterium were first described over a century ago and were quickly associated with a healthy intestinal tract due to their numerical dominance in breast-fed babies as compared to bottle-fed infants. Health benefits elicited by bifidobacteria to its host, as supported by clinical trials, have led to their wide application as probiotic components of health-promoting foods, especially in fermented dairy products. However, the relative paucity of genetic tools available for bifidobacteria has impeded development of a comprehensive molecular understanding of this genus. In this review we present a summary of current knowledge on bifidobacterial metabolism, classification, physiology and genetics and outline the currently available methods for genetically accessing and manipulating the genus.

Background: Tumor metastasis is one of the main causes of death in cancer patients; however, the mechanism controlling metastasis is unclear. The posttranscriptional regulation of metastasis-related genes mediated by AT-rich interactive domain-containing protein 4A (Arid4a), an RNA-binding protein (RBP), has not been elucidated.

Methods: Bioinformatic analysis, qRT-PCR, immunohistochemistry, and immunoblotting were employed to determine the expression of Arid4a in breast tumor tissues and its association with the survival of cancer patients.

High tumour mutational burden (TMB-high), identified through comprehensive genomic profiling (CGP), is a biomarker that predicts the efficacy of immune checkpoint inhibitors. CGP testing is recommended for rare cancers with limited effective treatment options. Here, we provide the first report of a malignant phyllodes tumour of the breast demonstrating TMB-high status and effective treatment with pembrolizumab.

Serine integrases (Ints) have gained prominence and have been extensively used in Synthetic Biology due to their ability to modify DNA sequences. Ints are recombinases encoded by the phage genome and have been used to unidirectionally catalyze an insertion, excision, or inversion of a specific DNA sequence between the two attachment sites () (bacterial attachment site) and (phage attachment site). The entire process is highly specific and accurate; therefore, Ints are widely used in genetic engineering and have been extensively studied due to their unique site-specific recombination properties and potential genome editing applications.

Background: Atrial fibrillation (AF) and heart failure (HF) frequently coexist and mutually influence each other. The association between AF and the subtype of HF, Ischaemic heart failure (IHF), remains insufficiently described, despite their high prevalence. Hence, comprehending their underlying pathophysiological mechanisms and identifying new therapeutic targets are urgently needed.

Solid tumors present a formidable challenge in oncology, necessitating innovative approaches to improve therapeutic outcomes. Proteoglycans, multifaceted molecules within the tumor microenvironment, have garnered attention due to their diverse roles in cancer progression. Their unique ability to interact with specific membrane receptors, growth factors, and cytokines provides a promising avenue for the development of recombinant proteoglycan-based therapies that could enhance the precision and efficacy of cancer treatment.
