  • Publication number: 20250127909
    Abstract: Methods of regulating expression of a target gene in a cell are provided. Aspects of the methods contacting the cell with a compound having a first moiety covalently linked to a second moiety, wherein: (i) the first moiety exhibits specific binding to a first endogenous protein; (ii) the second moiety exhibits specific binding to a second endogenous protein distinct from the first endogenous protein; and (iii) upon contacting the cell, the first endogenous protein and the second endogenous protein are spatially complexed to each other via the compound to yield a gain-of-function in the cell and thereby activate a process not normally controlled by either of the first and second endogenous proteins.

  • Patent number: 11980613
    Abstract: This disclosure provides methods of using BAF complex modulating compounds as inhibitors of BAF-mediated transcription in target cells. The BAF complex modulating compounds include 12-membered macrolactam compounds that can target a BAF-specific subunit (e.g., ARID1A) to prevent nucleosomal positioning, relieving transcriptional repression of HIV-1. The subject methods can provide for reversal of latency of HIV-1 in cells in vitro or in vivo. Use of the macrolactam BAF complex modulating compounds represent a method of HIV latency reversal with a unique mechanism of action, which can be optionally combined with other Latency Reversal Agents to improve reservoir targeting. The subject methods can be utilized in conjunction with any convenient methods of treating HIV or HIV latency, including methods related to immune system activation, antiretroviral therapies and/or anti-HIV agents.

  • Publication number: 20230304024
    Abstract: Methods of modulating transcription of a target gene in a cell (which may be in vitro or in vivo) are provided. Aspects of the methods employ a transcription factor-chemical inducer of proximity (TF-CIP) system to modulate, e.g., enhance or reduce, transcription of a target gene in a cell. Embodiments of the methods include providing in a cell a chemical inducer of proximity (CIP) which links a first endogenous anchor transcription factor that binds to a promoter of the target gene and a second endogenous transcription modulating factor (e.g., a transcription factor or transcription repressor), wherein CIP mediated linkage of the anchor transcription factor and transcription modulating factor modulates transcription of the target gene in the cell. Also provided are compositions that find use in practicing methods of the invention.

  • Publication number: 20220233563
    Abstract: Methods of treatment based on a neoplasm's responsiveness to anthracycline are provided. Chromatin accessibility or expression levels of chromatin regulatory genes are used in some instances to determine whether a neoplasm will respond to anthracycline treatment. Anthracyclines are utilized to treat various individuals' neoplasms and cancers, as determined by their anthracycline responsiveness.

  • Patent number: 11267809
    Abstract: The invention provided here creates a new paradigm for the treatment of a variety of conditions where modulation of a BAF complex is desired. The disclosure that follows outlines a strategy for modulating a BAF complex in a cell, and provides effective compounds, pharmaceutical compositions, development strategies, and treatment protocols, and describes many of the ensuing benefits. A new family of BAF complex modulating compounds has been developed based on a new chemical scaffold including a 12-membered macrolactam core structures. Contacting target cells in vitro or in vivo with the compounds and compositions of this invention can selectively inhibit the activity of BAF complexes in such cells. Some of the BAF complex modulating compounds in this family are particularly effective agents for treating cancer in conjunction with a ATR inhibitor.

  • Patent number: 10976320
    Abstract: Methods for identifying and treating cancer patients likely to respond to topoisomerase inhibitors or likely to fail to respond to topoisomerase inhibitors are provided. The methods take advantage of the newly discovered role of BAF complexes in decatenation of DNA by topoisomerase IIa. Cancer cells are frequently at least partly defective in BAF complex activity. Such cells are targeted for therapy using certain topoisomerase IIa inhibitors according to the disclosed methods of treatment. Therapy of such cells using other topoisomerase inhibitors should be avoided.
