Objective: Dysregulation of microRNA expression could attenuate the course of chronic lymphocytic leukemia (CLL). Therefore, the aim of our study is to address the association between miR-29a expression and other prognostic markers in CLL patients.
Methods: miR-29a expression was determined by quantitative real-time PCR in the plasma of 158 CLL patients at diagnosis beside 21 healthy controls in a prospective study.
Results: The levels of miR-29a expression were found to be significantly higher in CLL patients as compared to healthy controls (P<0.001). Moreover, a significant association between high miR-29a expression and poor prognostic markers (high expression of CD38 and ZAP70, high LDH levels, Stage III Rai stage, unfavorable cytogenetic finding, time to first treatment (TTFT) and patients outcome (P<0.001 for All). Using ROC curve, we have reported that miR-29a expression levels (29a<0.76 vs >0.76) is able to discriminate severity subgroups of CLL patients.
Conclusion: Up regulation of miR-29a expression at CLL diagnosis was detected. Determination of miR-29a expression concentration levels at diagnosis could be demonstrated as a prognostic biomarker in CLL patients.

Glioblastoma multiforme (GBM) is the most prevalent, treatment-resistant, and fatal form of brain malignancy. It is characterized by genetic heterogeneity, and an infiltrative nature, and GBM treatment is highly challenging. Despite multimodal therapies, clinicians lack efficient prognostic and predictive markers.

Background: Granulosa cell proliferation and survival are essential for normal ovarian function and follicular development. Long non-coding RNAs (lncRNAs) have emerged as important regulators of cell proliferation and differentiation. Nuclear paraspeckle assembly transcript 1 (NEAT1) has been implicated in various cellular processes, but its role in granulosa cell function remains unclear.

: Sjögren's syndrome (SS), an autoimmune disease, was characterized by sicca syndrome and systemic manifestations, presenting significant treatment challenges. Exosomes, naturally derived nanoparticles containing bioactive molecules, have garnered interest in regenerative medicine. The present study aimed to elucidate the immunoregulatory properties and mechanism of exosomes obtained from the stem cells derived from human exfoliated deciduous teeth (SHED-exos) in SS-induced sialadenitis.

People with HIV (PWH) have an elevated risk of cardiovascular disease compared to those without HIV. This study aimed to investigate the relative serum expression of microRNAs (miRNAs) associated with arterial stiffness, a significant marker of cardiovascular disease. A total of 36 male PWH and 36 people without HIV, matched for age, body mass index, pack years, and dyslipidemia, were included in the study.

Paclitaxel is a widely used chemotherapeutic agent for the treatment of breast cancer (BC), including as a front-line treatment for triple-negative breast cancer (TNBC) patients. However, resistance to paclitaxel remains one of the major causes of death associated with treatment failure. Multiple studies have demonstrated that miRNAs play a role in paclitaxel resistance and are associated with both disease progression and metastasis.
