Endoglin mediates the tumor‐ and metastasis‐promoting traits of stromal myofibroblasts in human breast carcinomas

Molecular Oncology, EarlyView.
Carcinoma‐associated fibroblasts (CAFs) in tumors influence cancer progression. We identified endoglin (ENG) as a key factor in TGF‐β signaling in myofibroblastic CAFs (myCAFs), linked to poor breast cancer outcomes. Inhibiting ENG on myCAFs suppressed the TGF‐β‐Smad2/3 pathway, reducing primary tumor growth and metastasis.

Tumores testiculares na infância

Revista do Colégio Brasileiro de Cirurgiões
Testicular and paratesticular prepuberal tumors are rare. They represent around 1% of the total of tumors of infancy. They subdivide in 2 groups: germ cells tumors and non germ cells tumors, being able to occur in all the ages, and about 75% are ...

Frequent PD-L1 expression in testicular germ cell tumors

British Journal of Cancer, 2015
Background:Many testicular germ cell cancers are curable despite metastatic disease, but about 10–15% of patients fail cisplatin-based first-line treatment. Immunotherapy is considered as additional treatment approach for these patients.

Possible role of human ribonuclease dicer in the regulation of R loops

FEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

CT features of mature teratoma in the mediastinum of two young adults—a report of two cases

The Egyptian Journal of Radiology and Nuclear Medicine, 2020
Background Germ cell tumors prefer gonadal regions, but they can be expected in extragonadal sites such as the anterior mediastinum, which is the commonly involved region after gonads.

Role of microRNAs in mammalian spermatogenesis and testicular germ cell tumors.

Reproduction, 2015
microRNAs (miRNAs) are a class of small endogenous RNAs, 19-25 nucleotides in size, which play a role in the regulation of gene expression at transcriptional and post-transcriptional levels.

Short peptide perturbs spermatogenesis via immune microenvironment dysregulation and mitochondrial imbalance

FEBS Open Bio, EarlyView.
In the blood–testis barrier, occludin is crucial for tight junctions. This study demonstrates that occludin‐targeting short peptides disrupt junction integrity, inducing immune cell infiltration, tumor necrosis factor‐α/interleukin‐6 secretion and mitochondrial dysfunction, ultimately triggering apoptosis.

Machine Learning‐Enabled Polymer Discovery for Enhanced Pulmonary siRNA Delivery

Advanced Functional Materials, EarlyView.
This study provides an efficient approach to train a machine learning model by merging heterogeneous literature data to predict suitable polymers for siRNA delivery. Without the need for extensive laboratory synthesis, the machine learning enabled a virtual screening and successfully predicted a polymer that is validated for effective gene silencing in

Testicular mixed germ cell tumor in a newborn child: A rare case

Journal of Indian Association of Pediatric Surgeons, 2019
Testicular tumors are rare in children but highly treatable and usually curable. Seminomas are extremely rare in prepubertal children. Among nonseminomatous germ cell tumors, the most common are teratomas and yolk sac tumors. Mixed germ cell tumor (MGCT)
