Adipokines in obesity and glucose homeostasis

Obesity is the abnormal increase in adipose tissue mass. This phenomenon increases the likelyhood of a number of diseases such as heart disease, high blood pressure, type 2 diabetes, obstructive sleep apnea, osteoarthritis, and some kinds of cancer.

Obesity is probably the leading preventable cause of death worldwide. People are considered to be obese if their body mass index (BMI) exceeds a value of 30. The mainstays of treatment of obesity remain dieting and physical exercise.

Nevertheless, adipose tissue (fat) cannot be considered a worthless batch of “lard”, but rather a fascinating vital tissue that in addition to being the body’s major energy reservoir, plays a central role as a secretory organ. Research in this field has already lead to exciting results related to both fat reduction, insulin resistance and to the development of robust tools to study diabetes / obesity.

Adipokines are factors secreted by adipose tissue which carry messages to other parts of the body. I would like to briefly introduce the role of adipokines in the regulation of body weight and glucose homeostasis. [Read more…]

Secretome biomarker identification: tech tips for selecting the most suitable tools

In a previous post, I mentioned that the secretome is becoming a very hot topic in the world of proteome analysis, and even a crucial study subject. Today, I’d like go a step further and shed some light on how to analyse it.

Let’s see what the options are…

Interactions between cancer and immune cells via cytokine networks

Pr. Ruo-Pan Huang’s team has just published a review detailing the interactions between cancer and immune cells.

This overview describes the key cytokine signals, cell–cell signal networks in the tumor microenvironment during cancer diseases. It also demonstrates the power of antibody arrays and multiplex immunoassays as unique research tools to decipher cytokine networks during cancer and inflammation processes.
