Survival Mechanisms

Cancer treatments are constantly evolving with new approaches to improve patient outcomes. Despite progresses, too many patients remain refractory to treatment due to either the development of resistance to therapeutic drugs and/or metastasis occurrence. Growing evidence suggests that these two barriers are due to transient survival mechanisms that are similar to those observed during stress response. We review the literature and current available open databases to study the potential role of stress response and, most particularly, the involvement of Stress Granules (proteins) in cancer. We propose that Stress Granule proteins may have prognostic value for patients.

Insight Into

Lignans, phenolic plant secondary metabolites, are derived from the phenylpropanoid biosynthetic pathway. Although, being investigated for their health benefits in terms of antioxidant, antitumor, anti-inflammatory and antiviral properties, the role of these molecules in plants remains incompletely elucidated; a potential role in stress response mechanisms has been, however, proposed. In this study, a non-targeted metabolomic analysis of the roots, stems, and leaves of wild-type and PLR1-RNAi transgenic flax, devoid of (+) secoisolariciresinol diglucoside ((+) SDG)—the main flaxseed lignan, was performed using 1H-NMR and LC-MS, in order to obtain further insight into the involvement of lignan in the response of plant to osmotic stress. Results showed that wild-type and lignan-deficient flax plants have different metabolic responses after being exposed to osmotic stress conditions, but they both showed the capacity to induce an adaptive response to osmotic stress. These findings suggest the indirect involvement of lignans in osmotic stress response.

Extensive efforts recently witnessed the complexity of cancer biology; however, molecular medicine still lacks the ability to elucidate hidden mechanisms for the maintenance of specific subclasses of rare tumors characterized by the silent onset and a poor prognosis (e.g., ovarian cancer, pancreatic cancer, and glioblastoma). Recent mutational fingerprints of human cancers highlighted genomic alteration occurring on epigenetic modulators. In this scenario, the epigenome dependency of cancer orchestrates a broad range of cellular processes critical for tumorigenesis and tumor progression, possibly mediating escaping mechanisms leading to drug resistance. Indeed, in this review, we discuss the pivotal role of chromatin remodeling in shaping the tumor architecture and modulating tumor fitness in a microenvironment-dependent context. We will also present recent advances in the epigenome targeting, posing a particular emphasis on how this knowledge could be translated into a feasible therapeutic approach to individualize clinical settings and improve patient outcomes.

Pituitary Adrenal Axis

The hypothalamic-pituitary-adrenal axis is a key mediator of the stress response in humans. The corticotropin-releasing factor (CRF) type 1 receptor (CRFR-1) in the pituitary gland is a gatekeeper for that response, and the CRFR-1 receptor is also present in many other mood- and cognition-related neural structures. Behaviorally, a number of relationships between stress and psychiatric disorders can be observed: chronic or repeated stress is associated with onset of depression; stressors can cause a recovering alcoholic to relapse; overactive stress responses mark many anxiety disorders; and insomnia can arise from an overactive stress response. Thus, a CRFR-1 antagonist could be useful for treating or preventing the consequences of CRF-mediated stress in depression, anxiety, insomnia, and substance abuse.

Aging has been associated with a series of pathophysiological processes causing general decline in the overall health of the afflicted population. The cumulative line of evidence suggests an important role of oxidative stress in the development and progression of the aging process and metabolic abnormalities, exacerbating adipocyte dysfunction, cardiovascular diseases, and associated complications at the same time. In recent years, robust have established the implication of Na/K-ATPase signaling in causing oxidative stress and alterations in cellular mechanisms, in addition to its distinct pumping function. Understanding the underlying molecular mechanisms and exploring the possible sources of pro-oxidants may allow for developing therapeutic targets in these processes and formulate novel intervention strategies for patients susceptible to aging and associated complications, such as obesity and cardiovascular disease. The attenuation of oxidative stress with targeted treatment options can improve patient outcomes and significantly reduce economic burden.

Abstract The current state of the diagnosis and management of thyroid disease cannot be separated from the larger context of women’s health for the following reasons: (1) the disproportionate incidence and prevalence of functional and structural thyroid diseases among women vs men; (2) the role of thyroid health on fertility, pregnancy, and postpartum; and (3) the challenge posed in managing the nonspecific symptoms of functional thyroid disease in the context of menopause. Here, we explore the hypothesis that sex bias has played a role in the management of thyroid diseases historically and has extended into the modern medical era. Once knowledge gaps that may have resulted from sex bias are recognized, we can strive to overcome this bias and develop better treatments to improve patient outcomes universally.
