Use of novel genomic sequencing to characterise carcinoma of unknown primary (CUP) in patient with axillary lymphadenopathy.

Carcinoma of unknown primary (CUP) comprises 2-5% of cancer diagnoses worldwide, with a prevalence that has modestly declined with increased availability of advanced diagnostic tools such as next-generation sequencing (NGS). This case presentation illustrates the possibilities and gaps that remain with improving diagnostic capabilities in identifying and effectively treating CUP. This is the case of a rapidly enlarging right axillary mass without a primary tumour site and histological evaluation demonstrating a poorly differentiated neoplasm.

Sweat chloride reflects CFTR function and correlates with clinical outcomes following CFTR modulator treatment.

Background: Highly effective CFTR modulators improve CFTR function and lead to dramatic improvements in health outcomes in many people with cystic fibrosis (pwCF). The relationship between measures of CFTR function, such as sweat chloride concentration, and clinical outcomes in pwCF treated with CFTR modulators is poorly defined. We conducted analyses to better understand the relationships between sweat chloride and CFTR function in vitro, and between sweat chloride and clinical outcomes following CFTR modulator treatment.

Roles for Prlhr/GPR10 and Npffr2/GPR74 in Feeding Responses to PrRP.

Several groups of neurons in the NTS suppress food intake, including Prlh-expressing neurons (NTS cells). Not only does the artificial activation of NTS cells decrease feeding, but also the expression of Prlh (which encodes the neuropeptide PrRP) and neurotransmission by NTS neurons contributes to the restraint of food intake and body weight, especially in animals fed a high fat diet (HFD). We used animals lacking PrRP receptors GPR10 and/or GRP74 (encoded by Prlhr and Npffr2, respectively) to determine roles for each in the restraint of food intake and body weight by the increased expression of Prlh in NTS neurons (NTS mice) and in response to the anorectic PrRP analog, p52.

Leptin, NK cells, and the weight of immunity: Insights into obesity.

Obesity is a chronic inflammatory disease that affects more than 1 billion people worldwide and is associated with various metabolic and physiological dysfunctions, directly impacting the dynamics of the immune response, partly due to elevated leptin levels. Leptin is an important peptide hormone that regulates neuroendocrine function and energy homeostasis, with its blood levels reflecting energy reserves, fat mass, or energy deprivation. This hormone also plays a fundamental role in regulating immune function, including the activity of NK cells, which are essential components in antiviral and antitumor activity.
