Differentiation of Murine C2C12 Myoblasts Strongly Reduces the Effects of Myostatin on Intracellular Signaling
2020
Alongside in vivo models, a simpler and more mechanistic approach is required to study the effects of myostatin on skeletal muscle because myostatin is an important negative regulator of muscle size. In this study, myostatin was administered to murine (C2C12) and human (CHQ) myoblasts and myotubes. Canonical and noncanonical signaling downstream to myostatin, related ligands, and their receptor were analyzed. The effects of tumorkines were analyzed after coculture of C2C12 and colon cancer-C26 cells. The effects of myostatin on canonical and noncanonical signaling were strongly reduced in C2C12 cells after differentiation. This may be explained by increased follistatin, an endogenous blocke…
Prognostic Value of Sarcopenia in Metastatic Colorectal Cancer Patients Treated with Trifluridine/Tipiracil
2021
Sarcopenia is common in metastatic colorectal cancer (mCRC), increases the risk of treatment-related toxicity and reduces survival. Trifluridine/tipiracil (TT) chemotherapy significantly improved survival in refractory mCRC patients, but the prognostic and predictive role of pretherapeutic sarcopenia and variation in the skeletal muscle index (SMI) during this treatment has not been investigated so far. In this retrospective, observational study, clinical data on mCRC patients treated with TT at six cancer centres in Poland were collected. Computed tomography (CT) scans acquired at the time of initiation of TT (CT1) and on the first restaging (CT2), were evaluated. SMI was assessed based on…
Influence of cachexia and sarcopenia on survival in pancreatic ductal adenocarcinoma: a systematic review.
2014
Abstract Background/objectives Cachexia affects ∼80% of pancreatic cancer patients. An international consensus defines cachexia as an ongoing loss of skeletal muscle mass (sarcopenia) with or without loss of fat, which impairs body functioning and cannot be reversed by conventional nutritional measures. Weight loss percentage and elevated inflammation markers have been employed to define this condition earlier. This review aimed to assess the prevalence and consequences of cachexia and sarcopenia on survival in patients with pancreatic ductal adenocarcinoma. Methods The systematic review was performed by searching the articles with preset terms published in PubMed and Cochrane Database unti…
Beyond Physical Exercise: The Role of Nutrition, Gut Microbiota and Nutraceutical Supplementation in Reducing Age-related Sarcopenia
2021
Sarcopenia is a commonly prevalent geriatric condition mainly characterized by progressive loss of the skeletal muscle mass that results in noticeably reduced muscle strength and quality. Most of the geriatric population above 60 years of age are overweight, leading to the accumulation of fat in the muscles resulting in abated muscle function. The increased loss of muscle mass is associated with high rates of disability, poor motility, frailty and mortality. The excessive degeneration of muscles is now also being observed in middle-aged people. Therefore, geriatrics has recently started shifting towards the identification of early stages of the disability in order to expand the life span o…

IPERSENSIBILITÀ AL GLUTINE NELL’ANZIANO. PRESENTAZIONE DI UN CASO CLINICO
2015
La celiachia è una malattia immunomediata scatenata dall’ingestione di glutine che, in soggetti geneticamente predisposti, determina un processo infiammatorio intestinale con conseguente malassorbimento e manifesta-zioni extraintestinali. Fino ad alcuni anni fa era considerata una patologia rara, tipica dell’età infantile; lo scenario epidemiologico della celiachia, oggi, è totalmente cambiato, grazie anche all’introduzione di test sierologici ad elevata sensibilità e specificità come gli anticorpi anti-endomisio (EMA) e gli anticorpi anti-transglutaminasi tissutale (tTG). Studi epidemiologici basati sull’impiego dei test sierologici hanno dimostrato che la diagnosi di celiachia viene sempr…
Celiac disease in older persons: A case of seronegative disease
2017
A 68-year-old man with a history of smoking (former smoker of 40 cigarettes per day), euthyroid goiter, deep vein thrombosis and depression, came to our attention for weakness, cachexia, abdominal bloating and diarrhea lasting for almost six months. Furthermore, he had lost about 25 kilograms of weight in the last year and was bedridden for three months. Combining the results of serological, histopathological and genetic tests, he was diagnosed with a seronegative celiac disease. Gluten-free diet, combined with nutritional supplements and physical therapy, improved his clinical condition and allowed the recovery of weight and the walking ability. Celiac disease might be suspected in elderly…
TERAPIA DELLA SARCOPENIA
2014
La sarcopenia e la cachessia sono i disordini muscolari più comune negli adulti. La principale differenza tra le due condizioni è che, a livello istologico, la sarcopenia rappresenta una condizione età correlata che si accompagna a neurodegenerazione, mentre la cachessia è una malattia infiammatoria del muscolo, che è associata a perdita di tessuto adiposo e ad anoressia. E’ stato dimostrato che entrambe le condizioni, nonostante le differenze nella etiologia e fisiopatologia, rispondono positivamente a trattamenti che aumentano la massa e la forza muscolare. Il gold standard attuale della terapia della sarcopenia è l'esercizio fisico. Inoltre, esistono una serie di farmaci che sono disponi…
