EMBO e-talks: Stress kinases in cardiometabolic diseases (3 Nov 2021)

13/10/2021 /

On Wednesday 3 Novmber 2021 al 14:00 (CET), Guadalupe Sabio will talk at an EMBO e-talk about the role of stress kinases in cardiometabolic diseases.

The p38 mitogen-activated kinase (MAPK) family controls cell adaptation to stress stimuli. There are four different p38 family members with different roles in relation to cardiac development and function.

The first isoform demonstrated to play an important role in cardiac development was p38α; however, all p38 family members are now known to collaborate in different aspects of cardiomyocyte differentiation and growth. p38 family members have been proposed to have protective and deleterious actions in the stressed myocardium, with the outcome of their action dependent on the model system under study and the identity of the p38 family member activated.

In this talk, we summarize current understanding of the role of the p38 pathway in cardiac physiology and discuss recent advances in the field.

Uncovering the role of p38 family members in adipose tissue physiology

The complex functions of adipose tissue have been a focus of research interest over the past twenty years. Adipose tissue is not only the main energy storage depot, but also one of the largest endocrine organs in the body and carries out crucial metabolic functions. Moreover, brown and beige adipose depots are major sites of energy expenditure through the activation of adaptive, non-shivering thermogenesis.

In recent years, numerous signaling molecules and pathways have emerged as critical regulators of adipose tissue, in both homeostasis and obesity-related disease. Among the best characterized are members of the p38 kinase family. The activity of these kinases has emerged as a key contributor to the biology of the white and brown adipose tissues, and their modulation could provide new therapeutic approaches against obesity.

Here, we give an overview of the roles of the distinct p38 family members in adipose tissue, focusing on their actions in adipogenesis, thermogenic activity, and secretory function.

Stress-activated kinases signaling pathways in cancer development

Cancer is a large group of diseases characterized by abnormal cell growth that can lead to metastasis. It is the second leading cause of death worldwide, and its incidence is expected to rise over the next decades. Stress-activated protein kinases (SAPK) are important players in its regulation. Several studies have tried to unravel their role; however, their pro-tumorigenic or anti-tumorigenic properties are sometimes controversial.

In this review, we will discuss the main roles of the different SAPK in the control of tumor development through essential processes such as cell proliferation, apoptosis or invasiveness. We will also show the latest discoveries regarding the contribution of SAPK in shaping tumor microenvironment through the regulation of organ crosstalk and immune cell response during cancer progression.

All these studies are relevant examples of how SAPK offer new therapeutic avenues for cancer patients that may help increase their survival.
