DESCRIPTION

Targeting cancer complexity at origin and progression

Our research is focused on better understanding breast cancer initiation and, from acquired knowledge, to assess targeted prevention strategies. In parallel, we study pan-cancer vulnerabilities and the connection to a rare, lung metastatic disease, lymphangioleiomyomatosis (LAM).

Cancer Stem-like Cells Act via Distinct Signaling Pathways in Promoting Late Stages of Malignant Progression

1 de January de 2016/in Pujana's Lab/by miguel

Cancer Res. 2016 Mar 1;76(5):1245-59. doi: 10.1158/0008-5472.CAN-15-1631. Epub 2015 Dec 30. ABSTRACT Cancer stem-like cells (CSC) play key roles in long-term tumor propagation and metastasis, but their dynamics during disease progression are not understood. Tumor relapse in patients with initially excised skin squamous cell carcinomas (SCC) is characterized by increased metastatic potential, and SCC progression […]

Rankl Impairs Lactogenic Differentiation Through Inhibition of the Prolactin/Stat5 Pathway at Midgestation

24 de December de 2015/in Pujana's Lab/by miguel

Stem Cells. 2016 Apr;34(4):1027-39. doi: 10.1002/stem.2271. Epub 2016 Jan 13. ABSTRACT Prolactin and progesterone both orchestrate the proliferation and differentiation of the mammary gland during gestation. Differentiation of milk secreting alveoli depends on the presence of prolactin receptor, the downstream Jak2-Stat5 pathway and the transcription factor Elf5. A strict regulation of Rank signaling is essential […]

A validated gene regulatory network and GWAS identifies early regulators of T cell-associated diseases

13 de November de 2015/in Pujana's Lab/by miguel

Sci Transl Med. 2015 Nov 11;7(313):313ra178. doi: 10.1126/scitranslmed.aad2722. ABSTRACT Early regulators of disease may increase understanding of disease mechanisms and serve as markers for presymptomatic diagnosis and treatment. However, early regulators are difficult to identify because patients generally present after they are symptomatic. We hypothesized that early regulators of T cell-associated diseases could be found […]

Lymphangioleiomyomatosis Biomarkers Linked to Lung Metastatic Potential and Cell Stemness

14 de July de 2015/in Pujana's Lab/by miguel

PLoS One. 2015 Jul 13;10(7):e0132546. doi: 10.1371/journal.pone.0132546. eCollection 2015. ABSTRACT Lymphangioleiomyomatosis (LAM) is a rare lung-metastasizing neoplasm caused by the proliferation of smooth muscle-like cells that commonly carry loss-of-function mutations in either the tuberous sclerosis complex 1 or 2 (TSC1 or TSC2) genes. While allosteric inhibition of the mechanistic target of rapamycin (mTOR) has shown […]

FANCM c.5791C>T nonsense mutation (rs144567652) induces exon skipping, affects DNA repair activity and is a familial breast cancer risk factor

2 de July de 2015/in Pujana's Lab/by miguel

Hum Mol Genet. 2015 Sep 15;24(18):5345-55. doi: 10.1093/hmg/ddv251. Epub 2015 Jun 30. ABSTRACT Numerous genetic factors that influence breast cancer risk are known. However, approximately two-thirds of the overall familial risk remain unexplained. To determine whether some of the missing heritability is due to rare variants conferring high to moderate risk, we tested for an […]

Research Projects

The group works and collaborates to decipher the systems mechanisms of cancer development and progression, with the aim of developing more precise preventive and therapeutic approaches. The group combines in silico and wet-lab studies for the purpose of identifying cancer principles and vulnerabilities.
