Mule SN, Manchola NC, de Oliveira GS, Pereira M, Magalhães RDM, Teixeira AA, Colli W, Alves MJM, Palmisano G (2021) Proteome-wide modulation of S-nitrosylation in Trypanosoma cruzi trypomastigotes upon interaction with the host extracellular matrix. J Proteomics 231:104020. doi: 10.1016/j.jprot.2020.104020 PMID: 33096306

Objective: To map site-specific S-nitrosylated (SNO) proteins from Trypanosoma cruzi trypomastigotes incubated (MTy) or not (Ty) with extracellular matrix (ECM).

Summary: The results provide the first site-specific characterization of S-nitrosylated proteins in T. cruzi and their modulation upon ECM incubation before infection of the mammalian hosts. The reduction of S-nitrosylation upon incubation with ECM, associated with a rewiring of the subcellular distribution and intracellular signaling pathways, was confirmed.

Lim I, Mitsui R, Kameda M, Sellers DJ, Chess‐Williams R, Hashitani H (2021) Comparative effects of angiotensin II on the contractility of muscularis mucosae and detrusor in the pig urinary bladder. Neurourol Urodyn 40:102-111. doi: 10.1002/nau.24548 PMID: 33074588

Objective: To explore contractile actions of angiotensin II (AT2) on the muscularis mucosae (MM) of the bladder.

Summary: The MM appears to have great sensitivity to AT2, suggesting that MM may be the predominant target of contractile actions induced by AT2 in the bladder.

Usage: Induction of contractions with Anti-AT2R (1 nM – 1 µM). Immunofluorescence (10-100 pM).

Theranostics 11(6):2691-2705. doi: 10.7150/thno.50571 PMID: 33456567

Objective: To identify histone lysine demethylases (KDMs) with altered expression in chronic myelogenous leukemia (CML) and define their contribution to imatinib resistance.

Summary: KDM6A promotes imatinib-resistance in CML cells. The identification of the KDM6A/YY1/TRKA axis as a novel imatinib-resistance mechanism represents an unexplored avenue to overcome tyrosine kinase inhibitor resistance in CML.

Objective: To investigate how obesity shifts the metabolic landscape of the tumor microenvironment (TME) to inhibit T cell function and promote tumor growth.

Summary: High-fat diet – induced obesity impairs CD8+ T cell function in the murine TME, accelerating tumor growth.

PLoS One 15(12):e0243660. doi: 10.1371/journal.pone.0243660 PMID: 33296434

Objective: To investigate the involvement of neuronal nitric oxide synthase (nNOS) and the PINK1/Parkin pathway in soleus muscle atrophy induced by 14 days of hindlimb unloading (HU) in adult rats.

Summary: Excessive NO is not produced in atrophied soleus muscles despite nNOS accumulation, suggesting that excessive NO dose not mediate in soleus muscle atrophy at least after 14 days of HU.
