Post-transplant consolidation based on combination of lenalidomide and proteasome inhibitors in multiple myeloma

2021

Multiple myeloma (MM) is a hematological malignancy due to uncontrolled proliferation of neoplastic plasma cells in the bone marrow, associated to chromosomal instability and cytogenetic abnormalities, which could have an impact on prognosis. Response to treatment and survival of newly diagnosed myeloma patients is heterogeneous, with median overall survival ranging from two to more than ten years, due to clinical and biological factors. To warrant long-term control of disease, several strategies have been proposed in the last years, including short-term high-dose of treatment, named as consolidation, before maintenance. This review will discuss the role of consolidation in the current myel…

Vanadium Modulates Proteolytic Activities and MMP-14-Like Levels during Paracentrotus lividus Embryogenesis

2022

The increasing industrial use of vanadium (V), as well as its recent medical use in various pathologies has intensified its environmental release, making it an emerging pollutant. The sea urchin embryo has long been used to study the effects induced by metals, including V. In this study we used an integrated approach that correlates the biological effects on embryo development with proteolytic activities of gelatinases that could better reflect any metal-induced imbalances. V-exposure caused morphological/morphometric aberrations, mainly concerning the correct distribution of embryonic cells, the development of the skeleton, and the embryo volume. Moreover, V induced a concentration change …

Sialic acid-containing glycoproteins on renal cells determine nucleation of calcium oxalate dihydrate crystals

2001

Sialic acid-containing glycoproteins on renal cells determine nucleation of calcium oxalate dihydrate crystals. Background The interaction between the surfaces of renal epithelial cells and calcium oxalate dihydrate (COD), the most common crystal in human urine, was studied to identify critical determinants of kidney stone formation. Methods A novel technique utilizing vapor diffusion of oxalic acid was employed to nucleate COD crystals onto the apical surface of living cells. Confluent monolayers were grown in the inner 4 wells of 24-well culture plates. To identify cell surface molecules that regulate crystal nucleation, cells were pretreated with a protease (trypsin or proteinase K) to a…

PSMA6 gēna promotera poliadenozīna trakta polimorfismu asociācija ar bronhiālo astmu, aptaukošanos un 1. tipa cukura diabētu Latvijas populācijā

2015

Ubikitīna – proteasomu sistēma ir multienzīmatisks proteāžu komplekss, kas regule dažādus šūnu procesus. Šis sistēmas disregulācija var būt iesaistīta tādos cilvēka patoloģiju rašanās mehanismos kā 2. tipa cukura diabēts, juvenīlais idiopātiskais artrīts un Greivsa slimība. Tas var būt atkarīgs no proteasomas gēnu strukturālām pārmaiņām, kuri kodē proteasomu apakšvienības. Šajā pētījumā mēs analizējam asociāciju starp PSMA6 gēna promotera poly(A) (c. –655 An) mikrosatelīta garuma izmaiņām un bronhiālo astmu (BA), 1. tipa cukura diabētu (T1DM) un aptaukošanos (APT) Latvijas populācijā. PSMA6 gēna poly(A) polimorfisms tika analizēts ar gadījuma / kontroles pētījumu un bioinformātiskām program…

Dupuytren's contracture: an update of biomolecular aspects and therapeutic perspectives.

2005

The so-called fibrogenic cytokines, able to induce the growth of fibroblasts and their differentiation into myofibroblasts and to stimulate their production of extracellular matrix, are involved in the genesis of Dupuytren’s contracture. Although many studies have been made of biomolecular aspects of palmar fibromatosis, practical applications from them are still far from imminent because of the real difficulty of blocking their action in vivo, even in a chronic, progressive lesion such as Dupuytren’s disease. Consequently, surgical excision of the palmar fascia still remains the treatment of choice.

0331 : Pathophysiology of the ubiquitine ligase E3, PDZRN3, in the development of dilated cardiomyopathies

2015

Dilated cardiomyopathy is a major cause of heart failure with a poor prognostic. Molecular mechanisms underlying the transition toward the dilated phenotype are still not known. In heart, individual cardiomyocytes connect some with the others via their extremities by junctional platform (Intercalated Discs, ID) crucial for the mechanical coupling and the anisotropic conduction of the electric signal. In this project, we are interested in an Ubiquitine ligase E3 called PDZRN3, which is expressed and regulated in cardiomyocytes during their maturation. We have previously identified PDZRN3 involvement in the the Wnt Planar Cell Polarity (Wnt/PCP) signaling in vascular morphogenesis. In the hea…

Weight-teasing and eating disorders-a comparative study in adolescent and adult samples

2022

Disordered eating, unhealthy weight-control behaviours and body dissatisfaction are associated with diminished mental health. A key aspect that has been identified for the development of disordered eating behaviours and body dissatisfaction is to be teased. Additionally, the literature suggests that weight may affect the relationship between weight-teasing and disordered eating and body dissatisfaction, although this pattern is unclear. This study presents two cross-sectional studies with an adult and an adolescent sample. The adolescent sample comprised 15,224 participants, and the adult sample comprised 321 participants, all from Spain. Hierarchical regression analyses were conducted. Aim…

Late infantile neuronal ceroid lipofuscinosis: Quantitative description of the clinical course in patients withCLN2 mutations

2002

We examined 26 individuals with clinical and electron microscopic signs of late infantile neuronal ceroid lipofuscinosis (LINCL). In 22 cases, we found both pathogenic alleles. Sixteen patients exclusively carried either one or a combination of the two common mutations R208X and IVS5-1G > C. In the remaining cases, four missense mutations could be detected, of which R127Q, N286S, and T353P represent novel, previously not described alleles. A clinical performance score was developed by rating motor, visual, and verbal functions and the incidence of cerebral seizures in 3-month intervals during the course of the disease. A Total Disability Score was derived by summing up the single scores for…

Antimetastatic activity of adriamycin in combinations with proteinase inhibitors in mice

1990

The antimetastatic activity of adriamycin in combination with proteinase inhibitors was investigated in mice bearing the metastatic tumors L1210 leukemia, Lewis lung carcinoma or M5076 sarcoma. Leupeptin, a cathepsin B inhibitor, when administered as a single agent was devoid of antimetastatic activity but some therapeutic activity was noted in mice with Lewis lung carcinoma when the agent was administered in combination with adriamysin. Pepstatin A, a cathepsin D inhibitor, had no effect as a single agent in mice with L1210 leukemia but displayed some antimetastatic activity in mice with Lewis lung carcinoma. In mice with M5076 sarcoma the combination of pepstatin A and adriamycin resulted…
